Not everybody believes in death-bed confessions. Hear one:

Let no man deceive you with vain words or vain hopes or false notions of a slight and sudden repentance. As if heaven were a hospital founded on purpose to receive all sick and maimed persons that, when they can live no longer to the lusts of the flesh and the sinful pleasures of this world, can but put up a cold and formal petition to be admitted there. No, no, as sure as God is true, they shall never see the Kingdom of God who, instead of seeking it in the first place, make it their last refuge and retreat. --John Tillotson (1630-1694), Sermons

Today's Larry Burkett quote from Crosswalk said God doesn't fancy being the bailout man in the back of the boat when our finances sink us. I imagine he is even less inclined to be the last resort when we've snubbed him all our lives.
