Christians still have to deal with sin. When I was just beginning my ministry, an old preacher came to me and said, “David, remember this: Sin will take you further than you ever wanted to go. Sin will keep you longer than you ever wanted to stay, and sin will cost you more than you ever wanted to pay!” It is so true. Deal with sin. Learn how to conquer sin. The first thing to do is recognize that old man, that old sinful nature, still with you.
