Any intolerance is essentially a sin of pride. Intolerance has been around forever. Remember, Cain killed Abel over differences in the way they worshipped the same God. Everyone at some level has to deal with prejudicial propensities because we all have to deal with pride in ourselves. The only antidote to pride is a position of intentional humility.
Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, not looking to your own interests but each of you to the interests of the others. — Philippians 2:3-4
Yes, this can be tough, but we need to do it! The victory is won by Christ-like character, not by the loudest voice.
The compelling nature of Jesus is that people, for the first time, were able to catch a glimpse of God’s kingdom come. This “kingdom come” tore the veil of bigotry just as it tore the veil at the Temple upon Jesus’ death, never to be reestablished. It was and is, and should be a kingdom of equality, not for equality's’ sake, but because there is no focus on us. All focus belongs on the worship of and service to Jesus.
