Friendship is being there, no matter what the personal cost. It is refusing to count your difficulties, and choosing instead to count your opportunities. It is sacrificing your time and energy for the benefit of the other, to show them some genuine love and minister to their heart and soul.
Friendship takes work to cultivate and maintain. It takes continual effort if it is to be a Christ-honoring friendship. It means taking time to pray, keeping up with circumstances, rejoicing when they rejoice and weeping when they weep.
