Suppose a boxer did not attack his opponent but just tried to avoid punches in a bout. Then would he be able to win it? He would lose nine times out of ten. The same applies to our Christian life. If you are complacent in your Christian life thinking it is hard to live by God's Word, your faith can do little more than backslide. At the moment you lower your guard against sins saying, "It is not a great sin. It is almost nothing. Others do it," you will start to be stained with sins. It is just like a fish that stops swimming and is swept away by the current.
