Do not look at yourself from a human perspective. Paul says in 2 Cor 5:16. ‘Consequently, from now on we estimate and regard no one from a purely human point of view.’ Why? Because if any person is in Christ he is a new creation, a new creature altogether! There is nothing purely human (in the old fallen sense) about us! The old has passed away…. 
Everything of our old nature, our old self, the good bad and the ugly has passed away! How? Look at 2 Cor 5:14: “we are of the conviction that if One died for all, then ALL died.” We were crucified with Christ! It is the greatest mystery, wonder, and display of love and goodness that God would unite himself with us in becoming one of us.But he didn’t just become one of us, He died as us! When Jesus was crucified he wasn’t only paying for our sins but He was destroying them. When He died, we died. Everything of our old selves, our old nature, with it’s curses, diseases, good works, bad works, shame, guilt, condemnation EVERYTHING of the old has passed away, has gone, is no longer, does not exist! He has made us a new creation! Nothing of the old was used in the new making of us. We are a new creation altogether.
God himself has moved in, joined himself to us! He has become our life, our righteousness, our holiness, our joy and endless love! God in Jesus has married himself to us! I think the eternal curiosity of the angels will not only be about the forgiveness of God towards us, but that God would unite Himself with us! That we would be in Him, and He would be in us, as one, married, never to be separated again!
We are altogether new, altogether lovely and all of this is from the lover of our souls, our Father, our God!
