It's true that our society tolerates ways of behavior today that would have been rejected a few generations ago but does that make them right? Or can we honestly say we live in a better world because of them? For example, would anyone honestly argue that the widespread breakdown of the family today is a good thing? I doubt it.
The Bible tells us that God has told us what is wrong and what is right and the older I get, the more I appreciate the wisdom of those unchanging moral truths. Think, for example, of the Ten Commandments (which you will find in Exodus 20:1-17). They tell us to honor both God and our parents, and to avoid murder, adultery, stealing, lying and coveting what doesn't belong to us. They form the foundation of a stable society, and when we ignore them, both our lives and our society will suffer.
The real issue, however, is this: Who will run your life? Will you run it or will God? Don't answer too quickly, for it is a dangerous thing to turn your back on the God who made you. He loves you, and He knows what is best for you.
I urge you not to drift along in life, just following the crowd and doing what everyone else is doing. Instead, face your need of God and open your life to Christ. Then make the psalmist's prayer yours: "Direct me in the path of your commands, for there I find delight" (Psalm 119:35).
