It is no wonder that our Lord said, “Because thou art neither cold nor hot, I will spue thee out of my mouth,” for when the earnest Christian’s heart is full of fire it is sickening to talk with lukewarm people. Have not warm-hearted lovers of Jesus felt when they have been discouraged by doubtful sluggish people, who could see a lion in the way, as if they could put on express speed and run over them? Every earnest minister has known times when he has felt cold hearts to be as intolerable as the drones in the hive are to the working bees.
