In Me. Then In You.  As we relate to other people in the church (our neighbors), we will view and treat them in the way we think God views us and treats us.  If we view God as treating us with condemnation, we will treat those in the church with condemnation.  If however, we can see that God has justified and made us right through the work of Jesus alone and not based on our performance, we can begin to see those around us in the church with a similar view.   If I can grasp grace for me, I can begin to grasp grace for you.
