I recommend this article to you. (Sorry, but I’ve lost track of where I found the link) Here’s a brief snippet:

Grace is easily enough defined. It is simply love overcoming judgement. Another story might provide some insight. It seems that every soul is connected to God by an invisible string. Whenever someone turns their back on their Maker and commits a sin, that string is broken. The only thing to be done is for God to repair the connection by tying a knot in the string. Unfortunately this makes it a little bit shorter. Some people sin a great deal, and God is always having to tie knots in their cord. That’s why great sinners end up a lot closer to God.
