First, what's the harder thing to say -- "Your sins are forgiven" or "Get up and walk"? Well, anybody can say that sins are forgiven, but there's immediate proof if someone can get up and walk or not. Conversely, what's the harder thing to do -- forgive someone's sins or supernaturally heal someone? Both of them are impossible in the power of humans; the only way either can be done is in the power of God.

Give people the choice, and they will gravitate toward a lifestyle of ease and comfort. Get enough people together, and they will develop a society which celebrates the easy life and demonizes the difficult life.

A person is going to orient his life around what he values the most. That's how human nature works; that's how He designed us. We have a "God-shaped hole", and we can fill it with God, or we can fill it with a false god. And every false god is ultimately us (think about it).
