I preached this weekend about how the rich man, despite receiving from God more than he deserved, didn't give anything to the poor but decided to hoard it for himself.
If I were going to preach again, I would have focused on this phrase. The man really has lost his sense of stewardship, meaning that all we have and all we are comes from God. He thinks that abundance means he can relax. But God's expectation is that, with tremendous gifts come tremendous responsibility. This is why the gospel of prosperity, that believers should expect to be "taken care of" by God, is so preposterous. True believers shouldn't expect God to take care of them, they should expect God to give them responsibilities to take care of each other. God loves us, we must love one another.
