20Even though we can’t see God we can know about him. If we look at the things he has made we can know about him, that he is really great and really strong. Ever since he made the world we can look at everything that he made, and we can know about him from those things. So nobody can say that he doesn’t know about God.
21The trouble was this. Even though people could work this out about God, they really didn’t want to know him. They didn’t want to tell him, “Thank you, you really are the true God.” They couldn’t think properly about him. They could only think in stupid ways. They didn’t understand anything.
22They told everybody that they could think really good, but they were fools.
