I believe one reason God calls us to unity is because is it so contrary to the world. Left to our own devices we express independent, self-serving attitudes and agendas. How do I know that? Because that is what the world does without Christ. Christ is about unity. “There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus.” Galatians 3:28. Satan is about division. “For where there are envy, strife, and divisions among you, are you not carnal and behaving like mere men?” 1 Corinthians 3:3.
God wants us to stand apart from the rest of the world making His name famous by doing so. God spoke to His people through Moses, “The Lord will establish you as a holy people to Himself, just as He has sworn to you,if you keep the commandments of the Lord Your God and walk in His ways. Then all peoples of the earth shall see that you are called by the name of the Lord…” Deuteronomy 28:9-10.
We love and serve the One True God, may it be known through our unity.
