When Paul says, “If the dead are not raised, let us eat and drink,” he does not mean, “Let’s all become lechers.” He means, there is a normal, simple, comfortable, ordinary life of human delights that we may enjoy with no troubling thoughts of heaven or hell or sin or holiness or God–if there is no resurrection from the dead. And what stunned me about this train of thought is that many professing Christians seem to aim at just this, and call it Christianity. Paul did not see his relation to Christ as the key to maximizing his physical comforts and pleasures in this life.
