Sin is the insanity of forsaking the pursuit of your pleasure in God. Here’s the text: Jeremiah 2:12-13: “Be appalled O heavens, be shocked. Be utterly desolate, says the Lord. For my people have committed two great evils. They have forsaken me, the fountain of living waters and have hewed out for themselves cisterns, broken cisterns that can hold no water.” Tell me, what is evil? The definition of evil, that which appalls the universe, that causes the angels of God to say, “No! It can’t be!”…what is it? It is looking at God, the fountain of all-satisfying, living water, and saying “No thank you,” and turning to the television, sex, parties, booze, money, prestige, a house in the suburbs, a vacation, a new computer program, and saying “Yes!” That’s insane! And it causes all heaven to be appalled, according to Jeremiah 2:12.
