Christians often denounce “selfishness,” but the Bible shows rational self-interest as our main reason to follow God. Whether we look to the Old or New Testament, to believers, or to the God whom they serve, we see self-interest. We should check our understanding of the concept of “self-interest.” Those who denounce self-interest say we should follow Jesus because of who he is, but not because of what he can do for us. Is that what the Bible says?
God the Father is self-interested:
He does all that he pleases.
