Another fine point by James Montgomery Boice.
Three hundred years is a long time. What kept Enoch walking with God for three hundred years? He had an awareness of judgment coming. He had a sensitivity to the ungodliness of the age. And he drew closer to God as the reality of these things pressed in upon him. The way to graph it would be to make a circle, space these three items around the circle, and then show by arrows that each one influenced the other. The more Enoch was aware of the judgment, the more sensitive he was to sin. The more sensitive he was to sin, the closer he wanted to walk with God. The closer he walked with God, the more clearly he saw that judgment was necessary. Or the other way: the more clearly he saw the judgment coming, the closer he wanted to walk with God, and the closer he walked with God the more sensitive he was to ungodliness.
If you keep close to God, you will keep from sin. But if you sin persistently, you will fall away from God. Then you will rename the sin. You will not talk about pride, the great sin; you will call it “self-esteem,” “self-worth,” or what is “due to me.” You will not talk about gluttony and materialism; you will talk about “the good life.” You will not talk about disobedience; you will talk about “shortcomings.” You will not talk about the Ten Commandments and your violation of them; you will talk about your “mistakes.” It is only when you draw close to God that these things will become increasingly sinful in your sight.
