“Love your neighbor as yourself” is not a command to love yourself. It is a command to take your natural, already existing love of self and make it the measuring rod of your love for others. There is not a harder command in the Bible than this one. It means: Want to feed the hungry as much as you want to feed yourself when you get hungry. It means: Want to find your neighbor a job as much as you are glad you have a job. Want to help your fellow student get A's as much as you want to get A's. Want to help the person stalled on the freeway as much as you are glad you are not stalled on the freeway. Want to give the poor softball player a chance to play as much as you want to play the whole game. Want to share Christ with your neighbor as much as you are glad you know Christ yourself.
John Piper
