I have often said to my students, "Your number one troublemaker in life is the person you look at every day in the mirror. That's the person who's going to make it most difficult for you in the years ahead." That's true of all of us. Never underestimate the power of the old sin nature. Begin each day with a fresh act of yielding to the Holy Spirit of God. It is a decision to yield control of your life to him. You will be grateful you did, because only then will you enjoy life to the full.
