Diversity in the church is scriptural. It is holy. God himself is a manifestation of three vastly different entities communing together in unity. God has designed his people so that we need everyone in order to fully understand who He is. We know this because that is how He says heaven will be like:
Rev 7:9-10 After this I looked, and behold, a great multitude that no one could number, from every nation, from all tribes and peoples and languages, standing before the throne and before the Lamb!"
This is a picture of creation in all its diversity coming together to praise God. Let it be 'on earth as it is in heaven.'
But this environment doesn't just magically happen. This is not about being PC because it's popular thing to do—it's about Christ-driven redemption of a broken world. We must identify and actively combat the injustice and disparity that underlies our modern racial divisions. True reconciliation means bearing with one another, and sacrificing of ourselves to combat injustice in the lives of others.
