Wise people are good at choosing, forging, and keeping friendships. The marks of a true friend are constancy, carefulness, candor, and counsel. When you are liberated to be the great friend you need to be by the great friendship of Jesus on the cross, then you will find yourself getting, paradoxically, all the friends your heart needs.
