Romans 3:26 (CSB) God presented him (Jesus) to demonstrate his (God's) righteousness at the present time, so that he (Jesus) would be righteous and declare righteous the one who has faith in Jesus.

God's righteousness is revealed by the law and prophets and now we are declared righteous by God because God has declared His Son as righteous. We are no longer seen as separate from God but unified. And if we are all unified with God then we can be unified with each other. We are all attached to the same vine (John 15). We are all filled with the same spirit (1 Corinthians 12). Let us start living as one body and not many different individuals (John 17:11).

Philippians 2:1-4 (CSB) 1 If then there is any encouragement in Christ, if any consolation of love, if any fellowship with the Spirit, if any affection and mercy, 2 make my joy complete by thinking the same way, having the same love, united in spirit, intent on one purpose. 3 Do nothing out of selfish ambition or conceit, but in humility consider others as more important than yourselves. 4 Everyone should look out not only for his own interests, but also for the interests of others.
