Biblical Reading: Galatians 3:28
There is no longer Jew or Greek; there is neither slave nor free; there is no male or female; because you are all one in Christ Jesus.
God has spoken to us in different ways to keep his word, for example in this quoted verse God exhorts us that we are all a body in Christ and that there should be no difference in his people.
Let us make Galatians 3:28 a complete reality in this life, I say this because from ancient times until now there has always been racism among mortals, but God has never supported racism, in the sense that one race is superior to another as in character or intelligence, rich or poor, but if he established the children of Abraham as a distinct race until Christ came.
In the book of James 2: 1 we read: My brothers, may your faith in our glorious Lord Jesus Christ be without respect for people.
God advises us on this because God does respect people or the not discriminate against their creatures or make distinctions based on money, prestige, power, social position, surname, nationality or race or despise any person because of these distinctions.
When we go deeper into the word of God we find that God taught Peter three times about racism. First in the house of Cornelius (Acts 10: 15,28, 34-35), then in Antioch when Paul publicly rebuked him for withdrawing from the Gentiles to run after the Jews (Galatians 2: 11-14)
God loves all people without condition because all human beings have the same physical characteristics (with minor variations of course) but the most important thing is that all human beings were created in the image and likeness of God.
God loves the entire world and the entire world includes all ethnicities of humanity.
All forms of racism, prejudice and discrimination are affronted with the work of Christ on the cross, because Jesus died for the white, the black, the Indian, the rich, the poor ... for all the races of the earth.
Remember that prejudice is the preconceived opinion, generally negative, towards something or someone and God commands to love all our neighbors without respecting people.
