If there is one trial greater than another, it is the trial of being disappointed in those we love. It is a bitter cup, which all true Christians have frequently to drink. Ministers fail them. Relationships fail them. Friends fail them. . . . But let them take comfort in the thought, that there is one unfailing Friend, even Jesus, who can be touched with the feelings of their infirmities, and has tasted of all their sorrows. Jesus knows what it is to see friends and disciples failing Him in the hour of need. Yet He bore it patiently, and love them notwithstanding all. He is never weary of forgiving. Let us strive to do likewise.
