God’s PEOPLE judge one another because we are part of God’s KINGDOM and God’s TEMPLE
Or do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor men who practice homosexuality, (1 Corinthians 6:9)
The Spirit himself bears witness with our spirit that we are children of God, [17] and if children, then heirs—heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him. (Romans 8:16-17)
