When Christians only talk about sin in theory rather than as specific sins attached to real people we know and we fail to be appropriately transparent about our own sinfulness and its forgiveness in Christ, Christianity quickly becomes a very superficial religion of looking good. People feel like they have to put on an act of being perfect. We keep our struggles with despair to ourselves. And sin becomes something to hide rather than confess. But the reality is that God is love, He is for us. He seeks us out, even when we hide from Him. And He forgives all our sins.
