For Paul, good and evil are at war in his heart. He longs to please God with his entire being, but fleshly temptations assail him and make it impossible. Only because of grace, only because of Christ’s sacrifice, is he saved. And freed from this war, he rejoices that Christ has done what he could not do. He rejoices to be in right relationship with God and thanks God for unilaterally removing the barrier that separated him from God.
William Blake doesn’t put evil and good at war. They are both poles of the same reality. In his “Songs of Innocence and of Experience,” he even changes the name of evil into “experience.” When we are innocent children, life is wonderful. But when we grow up, we become aware of temptations and begin to sample them and “experience” life. Ultimately, it was God who made us to grow up in puberty and “wake up” to other realities, according to his view. Blake seemed to revel in the role of an iconoclast, asserting heresy for shock value, much like Edgar Allen Poe did when he forged the horror genre.
What’s your conception of evil and good? A popular theory from evolution dismisses entirely the idea. And since the notion of a completely amoral society is untenable (not to mention denying the obvious inborn conscience we all have), lately theorists have forwarded the notion that we “evolved” morals as “communal” animals. It will be interesting to see what sort of evidence scientists assemble to support this theory. It will be even more interesting to see if they can agree on what sort of behavior is morally acceptable or condemned. In the meantime, it seems that this notion is a frantic attempt to shore up evolution, which fails entirely to account for the intellectual and emotional complexity of humans, which corroborates better the Biblical version than man is separate from the animals, not evolved.
But while intellectual concepts are floated into public discussion and enjoy moments of popularity and then die out, be careful what concepts you choose for your own life. Because you will be held accountable for your choices. If you reject God because His system conflicts with your personal pleasures, you could wind up in hot water.
