In response, one of my students pointed out that Satan succeeds because his path is easier. You don't have to make a commitment. But as a result, you lose the happiness and joy that come from living righteously.
It's true. While Satan's side is easier and there are no rules to follow, there is also no reward. What a disappointment it will be to find that the lures and "promises" were all a big lie and there is nothing for you in the end. Like C. S. Lewis pointed out, God will say to us, "Thy will be done," and we'll get exactly what we chose. Satan is cleverly deceptive and only when he has you in his chains will you realize that your freedom has been taken away.
Happiness comes when we choose to say to God, "Thy will be done," and His blessings are poured out upon us as we make ourselves eligible for an eternal reward. Rules and guidelines (commandments) are there for our peace and safety. It may initially feel like they are limiting our freedom, but we will soon find that true freedom is possible only through obedience.
Christ's Atonement made it possible for us to return to our Father in Heaven. It's up to us to choose to make that possibility our reality!
