Paul offers a metaphor that interprets in a rather surprising way: While Christians are saved only by faith and belief in Christ, our works as Christians play a part in a reward to come in Heaven. Working with this metaphor, Jamin surveys similar explanations of the afterlife through Jesus' teachings and then invites us to let Christianity get so under our skin that our focus becomes entirely Heaven-focused. We don't need to live lives full of earthly riches now, but lives aimed at Heavenly riches later. And if we let Heaven get under our skin enough, we may just find that even basic things like our sex drives can be called into question.
