When a person becomes a Christian, he usually undergoes some radical life changes, especially if he has had an immoral background. Through the first steps of spiritual growth and self-denial, he gets rid of the large, obvious sins. But sad to say, many believers stop there. They don't go on to eliminate the little sins that clutter the landscape of their lives. Gordon MacDonald, in his book Ordering Your Private World, told of an experience in his own life that illustrates this truth. "Some years ago, when Gail and I bought the old abandoned New Hampshire farm we now call Peace Ledge, we found the site where we wished to build our country home strewn with rocks and boulders. It was going to take a lot of hard work to clear it all out....The first phase of the clearing process was easy. The big boulders went fast. And when they were gone, we began to see that there were a lot of smaller rocks that had to go too. But when we had cleared the site of the boulders and the rocks, we noticed all of the stones and pebbles we had not seen before. This was much harder, more tedious work. But we stuck to it, and there came the day when the soil was ready for planting grass."
