How We View People
If anyone is in Christ, that person is a new creation. A person reborn and having the nature of God rather than the nature of Adam.
This being the case, we are no longer constrained to view people the way the rest of the world views them--based on their behavior.
We, who are in Christ, can see people for who they really are; people loved by God.
We can remember that in Christ, God was reconciling the world to Himself.
We can remember that He has made us His ambassadors.
In this way, He makes His appeal to the world through us, "come and be reconciled." Rely upon the fact that this is what He's doing in you, Saint. Trust that it is so. Leave all the convicting, the convincing, and even the results, to Him.
Just interact naturally with those He puts in your path. Show them love. Show them that you see them as people God loves. He works in, through, and with your weak and faltering self, and His strength is even more apparent because of it.
(See 2 Corinthians 5:16-21 & 12:9)
