It's difficult, even painful, for Christians to daily suffer the full weight of our past sin. Often our past drives us forward like a blind animal fleeing from the sound of the hunter. Wherever we go it's always there, our sin, made so brutally clear to us in hindsight, like a big ship's anchor chained to our foot. Also, in this world, we most often bear the weight of past sin alone. Other Christians can't and won't carry it for us; no one wants to take it from us, and nobody wants to break the chain or do something that will ultimately relieve us of the weight. And why should they?
