True Mercy and Greater Justice (Jesus in Genesis #8)

Sermon Synopsis

\For 29 years, the residents of Lubang Island in the Philippines lived in fear of a mysterious figure in the jungle. This man would fire weapons at anyone approaching his territory and conduct raids on local businesses, stealing food and supplies. Despite their best efforts, local authorities could not apprehend him.

What the islanders didn't know was that this "crazy old man" was actually Hiroo Onoda, a Japanese army intelligence officer who had been dropped on the island during World War II. When the war ended, word never reached him. His last orders were clear: do not surrender, do not commit suicide, continue gathering intelligence, and wait for an officer to relieve you. For three decades, he faithfully followed those commands, unaware the war had ended.

The people of Lubang Island only saw a fragment of the story. They created their own narrative based on limited information, missing the broader context that would have explained everything.

When We Create Narratives About God

This same tendency affects how people understand God. Based on a single experience, a passage of Scripture, or something someone says, many create entire narratives about who God is—narratives that may be fundamentally flawed.

One man grew up in church and learned to pray as a child. When none of his prayers seemed to be answered, that glimpse of divine silence led him to conclude there was no God at all. He became an atheist based on that limited perspective.

Conversely, a woman experienced a dramatic rescue from addiction and atheism. God radically transformed her life, and from that powerful encounter, she concluded that God always wants to give victory—and if someone isn't experiencing victory, it must be due to lack of faith.

Both created comprehensive theologies from single slivers of experience.

When Churches Emphasize Only One Attribute

This problem extends beyond individuals to entire churches and denominations. Some congregations focus almost exclusively on God's love, allowing that single attribute to filter everything they preach, pray, and counsel. Others emphasize God's justice to the exclusion of nearly everything else.

Both approaches lead to theological imbalance and practical problems in Christian living.

The passage examined in Genesis 18 refuses to allow such one-dimensional thinking. This challenging text forces readers to see God as both perfectly just and profoundly merciful—simultaneously and without contradiction.

Abraham Encounters God at Mamre

Genesis 18 opens with the Lord appearing to Abraham by the oaks of Mamre. Abraham was sitting at his tent door during the heat of the day when he looked up and saw three men standing before him.

This marked the sixth interaction between God and Abraham, but the first time God appeared in physical form—what theologians call a theophany. The conviction held by many biblical scholars is that such Old Testament appearances of God in human form were manifestations of the pre-incarnate Christ.

Abraham's response was remarkable. At 98 years old, he ran toward these visitors. Elderly men didn't run in that culture. Wealthy men with servants didn't personally attend to guests. Yet Abraham threw aside cultural conventions and his own dignity, running to meet them and bowing to the ground like a servant.

He recognized who this was: the Lord himself.

Abraham immediately became like a waiter at a fine restaurant, instructing Sarah to prepare food and standing ready to serve his divine guests hand and foot. His actions demonstrated that despite this being the first physical manifestation, he knew exactly who he was encountering.

The Promise Reiterated

The first part of this conversation revisited familiar territory. God reiterated the promise that Abraham would have a son, but this time with specific timing: within one year, Sarah would give birth.

This interaction likely occurred only days or weeks after the covenant of circumcision in Genesis 17. But now God spoke loudly enough for Sarah to overhear from inside the tent. When she heard that she would bear a child in her old age, she laughed in disbelief—and God confronted her about it.

Having told them what they wanted to hear, God now prepared to tell them what they needed to hear.

God Reveals His Plans for Sodom

After the meal concluded, the men rose and looked down toward the city of Sodom in the valley below. The two angels accompanying Jesus prepared to depart, but Abraham remained standing before the Lord.

Then God spoke words that would change the direction of the conversation entirely:

"Shall I hide from Abraham what I am about to do, seeing that Abraham shall surely become a great and mighty nation, and all the nations of the earth shall be blessed in him? For I have chosen him that he may command his children and his household after him to keep the way of the Lord by doing righteousness and justice."

God explained His reasoning: Abraham would become the father of a great nation and needed to understand how to lead people in righteousness and justice. Since God was about to execute justice, He would share His plans with Abraham.

Then came the sobering announcement: "Because the outcry against Sodom and Gomorrah is great, and their sin is very grave, I will go down to see whether they have done altogether according to the outcry that has come to me."

Abraham understood immediately what this meant. God had come to destroy these cities.

Understanding the Sin of Sodom

Some modern interpreters debate why God destroyed Sodom and Gomorrah. The cities are referenced over 20 times in Scripture, and several passages explicitly state the reasons for their judgment.

Ezekiel 16:49 describes Sodom as a city of excess and plenty that refused to care for the poor and needy. Isaiah references their refusal to surrender to God and their flagrant display of sin. Jeremiah mentions adultery and walking in lies. The book of Jude directly states they were destroyed for sexual immorality and pursuit of unnatural desires.

In Genesis 19, when the two angels entered Sodom, all the men of the city—both young and old—surrounded Lot's house demanding he send out his visitors so they could gang rape them. This reveals the depth of depravity that pervaded the city.

The complete picture shows cities characterized by:

  • Rampant sexual immorality and perversion
  • Oppression and neglect of the poor and vulnerable
  • Violence and abuse toward others
  • Theft and injustice
  • Arrogance and refusal to acknowledge God
  • Complete disregard for the dignity of human beings made in God's image

The destruction wasn't about a single category of sin—it was about comprehensive, society-wide evil that trampled on God's image bearers without restraint.

Why God's Justice Matters

For those who emphasize God's love above all else, the destruction of Sodom and Gomorrah creates discomfort. This discomfort, however, reveals something good: it demonstrates a proper valuing of human life.

But this perspective requires expansion. When considering God's justice, one must think about the victims—the poor neglected, the vulnerable exploited, the weak abused emotionally, financially, and physically. These people were being beaten down and trampled upon daily.

A God who would look at such systematic evil and say, "But I love everyone, so I'll let it pass," would not be a God worthy of worship. Justice demands that evil be addressed, that the oppressed be defended, that wrongs be made right.

The victims of Sodom and Gomorrah needed a God of justice. So do we.

Abraham's Negotiation: Justice Tempered by Mercy

As the two angels departed toward Sodom, Abraham remained standing before the Lord and initiated one of the most remarkable conversations in Scripture:

"Will you indeed sweep away the righteous with the wicked? Suppose there are fifty righteous within the city. Will you then sweep away the place and not spare it for the fifty righteous who are in it?"

God responded with extraordinary mercy: "If I find at Sodom fifty righteous in the city, I will spare the whole place for their sake."

Abraham continued negotiating—45 righteous? God would spare it. Forty? Yes. Thirty? Yes. Twenty? Yes. Finally, Abraham asked about ten righteous people, and God agreed He would spare the entire city for the sake of just ten righteous individuals.

Sodom and Gomorrah likely had populations of 1,000-2,000 people each. God was saying that if even one percent of the population was righteous, He would spare everyone—including the 99% who were thoroughly evil.

This is mercy on a breathtaking scale.

What Abraham Really Wanted

Abraham's nephew Lot lived in Sodom with his family. The negotiation likely reflected Abraham's concern for them. By stopping at ten, he was probably calculating: Lot makes one, his wife makes two, his two daughters make four—surely there must be six more righteous people in the entire city.

As Genesis 19 reveals, there weren't. In fact, when the angels arrived to rescue Lot, even his family had been so influenced by Sodom's culture that their righteousness was questionable. Yet for Abraham's sake, God showed mercy even to Lot's family, practically dragging them out of the city before its destruction.

Even in the midst of executing justice, God demonstrated profound mercy.

The Danger of Imbalanced Theology

Understanding both God's justice and mercy matters because emphasizing only one leads to serious problems:

The Problem with "God is Love" Alone

Focusing exclusively on God's love leads to licentiousness—the belief that one has a license to do whatever one wants. This thinking says: "I can drink excessively, engage in sexual immorality, steal, or pursue material excess without consequence because God loves me and will forgive me. We're tight."

This approach treats God's grace as permission to sin rather than power to overcome sin.

The Problem with "God is Just" Alone

Focusing exclusively on God's justice leads to legalism—the belief that God is primarily a harsh judge waiting to condemn every mistake. This creates fear-based religion where believers constantly worry whether they're measuring up.

It also produces judgmental attitudes toward others. When justice alone defines one's view of God, believers often assume the role of judge over their brothers and sisters, damaging relationships both within the church and outside it.

The Balance: Grace and Truth Together

When Christians hold both attributes in tension—understanding God as perfectly just and perfectly merciful—they can walk in both grace and truth. This balance enables them to:

  • Hold fellow believers accountable in love without harsh judgment
  • Extend grace to struggling sinners without excusing sin
  • Maintain healthy relationships inside and outside the church
  • Walk confidently with God, neither presuming on grace nor cowering in fear

How This Story Points to Jesus

The theophany in Genesis 18—Jesus appearing to Abraham—is the most obvious connection to Christ in this passage. But stopping there misses the deeper gospel foundation underlying the entire narrative.

This story ultimately leads to Jesus and the cross because it reveals an uncomfortable truth: humanity is far more like the people of Sodom and Gomorrah than anyone wants to admit.

The Doctrine of Human Sinfulness

The Apostle Paul, writing to the church in Rome, compiled five Old Testament quotations to paint a comprehensive picture of humanity's condition:

"None is righteous, no, not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good, not even one. Their throat is an open grave; they use their tongues to deceive. The venom of asps is under their lips. Their mouth is full of curses and bitterness. Their feet are swift to shed blood; in their paths are ruin and misery, and the way of peace they have not known. There is no fear of God before their eyes." (Romans 3:10-18)

This description feels harsh, negative, even depressing. The natural response is: "I'm not that bad."

Examining the Heart

But consider these questions honestly:

  • Have you ever lied?
  • Have you ever said something deeply hurtful to another person?
  • Have you ever wished harm would come to someone?
  • Have you ever actually hurt someone physically?
  • Have you ever engaged in sexual activity—mentally or physically—with someone who isn't your spouse?
  • Have you ever used money or time for selfish advantage?
  • Have you ever ignored God or tried to avoid Him?

Affirmative answers to any of these questions demonstrate the truth of Romans 3:10-18. This isn't comfortable, but it's essential truth for understanding both God's justice and His mercy.

The Cross: Where Justice and Mercy Meet

As a God of justice, the Lord cannot simply overlook sin. When people continue in patterns of lying, hurting, stealing, and ignoring God, they damage His image bearers. Because He loves His creation, this must be addressed.

The penalty for spiritual crimes—for sin—is death. If humanity pays that penalty themselves, they're separated from God forever.

This is where mercy enters the story. This is where the entire narrative of Sodom and Gomorrah points forward to the gospel.

At the cross, both God's justice and His mercy are fully displayed:

  • Justice is satisfied because a death occurred—the death required to pay for sin
  • Mercy is extended because Jesus died in humanity's place, allowing forgiveness and restored relationship with God

Just as Abraham sensed both justice and mercy in his conversation with God at Mamre, believers experience both through Christ. The cross declares that people are far more sinful than they want to admit, yet far more loved than they could ever imagine.

Practical Implications for Believers

Understanding God as both perfectly just and profoundly merciful transforms how Christians live:

For Those New to Faith

For anyone who has never surrendered their life to this God of mercy and justice, the invitation is clear but costly. Following Jesus isn't simply praying a prayer—it requires everything:

  • Time and priorities
  • Dreams and ambitions
  • Financial resources
  • Some relationships
  • Personal autonomy

Yet He is worth it. God loves people so deeply and wants to accomplish more in them and through them than they could imagine. While the world sells counterfeits promising the good life, only God offers something genuinely greater and more fulfilling. Those who give everything to follow Him look back at the end and wonder why they ever hesitated.

For Growing Believers

Christians who have leaned too heavily toward either "God is love" or "God is justice" need to expand their vision. Pulling back the curtains to see God more completely changes everything:

Those in "Camp Love" must learn: Genuine love includes accountability. Failing to address sin in a brother or sister's life isn't loving—it's neglectful. God's justice informs how His people should care for one another through truth-telling alongside grace.

Those in "Camp Justice" must learn: Walking as judge over everyone damages relationships and misrepresents God's character. He alone is the righteous Judge. Believers are called to extend the same mercy they've received, even while upholding God's standards.

Those who embrace both: Christians who hold justice and mercy in biblical tension can walk in grace and truth simultaneously. This balanced perspective strengthens relationships inside the church, improves witness outside the church, and deepens intimacy with God.

Worship Through Accurate Understanding

The goal isn't simply better theology for theology's sake. Understanding God accurately enables believers to worship Him rightly and represent Him faithfully to a watching world.

When Christians see God as He truly is—not as they wish He were, not as tradition has portrayed Him, not based solely on personal experience—they can:

  • Worship with authenticity and reverence
  • Follow with confidence and humility
  • Represent Him clearly to others
  • Live as people marked by both justice and mercy

The cross reveals both attributes perfectly. There, justice was executed as sin received its due penalty. There, love was demonstrated as Jesus gave everything to redeem humanity.

Conclusion: Expanding Our View

The people of Lubang Island created a narrative about Hiroo Onoda based on incomplete information. For 29 years, they saw him as simply a dangerous man in the jungle, missing the broader story that would have explained everything.

Christians face a similar temptation with God—to create comprehensive narratives based on partial glimpses of His character. Some emphasize His love to the exclusion of His justice. Others emphasize His justice to the exclusion of His mercy.

Genesis 18 refuses to allow such reductionism. In Abraham's encounter with God at Mamre, both attributes shine clearly. God comes prepared to execute justice on cities characterized by comprehensive evil and abuse of His image bearers. Yet in that same conversation, He demonstrates breathtaking mercy, willing to spare thousands of evil people for the sake of even ten righteous ones.

This dual revelation culminates at the cross, where justice and mercy meet perfectly. There, the gospel declares that humanity is far more sinful than anyone wants to admit—deserving the justice that fell on Sodom and Gomorrah. Yet humans are also far more loved than they could ever imagine—recipients of mercy that led God to sacrifice His own Son.

The call is to know Him fully—not partially, not selectively, but as He has revealed Himself in Scripture and supremely in Jesus Christ. Only then can believers make Him known accurately to a world that desperately needs to encounter both His justice and His mercy.
