Why should I not hate those who are different from me? We are taught in Christ to forebear one another. We do not forbear simply because it is the right thing to do. The answer has little to do with the reality of the differences. The answer is found in Why we are taught in Christ not to hate.
Love. Forbearance means that you will not judge others because they are not like you. It means that they will not judge you because you are not like them. Forbearance allows us to stand or kneel side by side to help, teach, encourage, exhort, hold, and comfort one another. We forbear with one another because God loves us. (John 3:16-17) I am to love each one of you because God loves each one of you. Love means that I am to forbear with you (1 Corinthians 13).
God redeems us all. So, because we are in Christ, we forbear with one another because God forbears with all of us. God loves the world so much that He gave us His Son and sacrificed Him for our salvation. God redeemed us in that salvation because He wants us to be His children regardless of our different cultures, backgrounds, and upbringing. God acknowledges all those things — and even uses them for his will — but His love for us is not based on our differences (Galatians 3:26-28).
Created. He loves everyone of us because He created each one of us in His image. He made us all in this same image. These physical, material, cultural, and historical differences between us have no part in the image of God. One day we will talk about the image. For now, let us say that God gave something to humans that made us like him. There is something in our nature that makes us like God so we can have an intimate relationship with him.
Do you see the idea? These things, these differences, we use to build barriers between us are nothing more than circumstances. Regardless of circumstances, we are bound together by a common love, redemption, and image that enables us to have an intimate relationship with God and one another. Forbearance. Redemption. Created. God is the common element — not our human circumstances.
