The Bible presupposes a love of self, a desire to experience pleasure and avoid pain, as inherent in the human makeup and as the ground of ethical imperatives. For example, loving ourselves is often used as a criterion in Scripture for the love of others (Mt. 19:19; Eph. 5:28). It is an assumed fact that we do love ourselves, and it is not evil to do so if it is done rightly… Thus Christianity, far from denigrating human worth, actually presupposes it in some of its fundamental teachings. Yet something has tragically blighted and twisted love of self into a gross perversion of God’s intent for His creatures. The fall of the human race into sin caused love of self to become mere selfishness. What was lost was a focus outside the self – that is, a love of God that gave it control and benevolence.
John Hannah
