Churches worldwide have different problems, but we have the same hope.
Through Jesus, we can be unified despite our differences. Democrat or Republican, Russian or Ukrainian, Racial differences, etc. Galatians 3:27 explains how those baptized into Christ are not different, but we are clothed with Christ. We are also Abraham's descendants and heirs to the promise if we belong to Christ.
Jesus didn't have to die individually for each people group. He has died once, and it covers all of us regardless of our differences. This allows us to enjoy our differences because those differences are no longer a threat. They are now uniquenesses that are intriguing rather than being divisive.
