He has no one to think about or care for, nor has he any capacity. A great preacher said not long ago to his congregation that he would tell them the mark of the beast, and that he also knew its number. He said the mark of the beast was selfishness, and its number was No. 1. Now the mark of the beast, selfishness, is in every man's breast, less or more. Paul spoke of this body of death.
Science speaks of it in almost precisely the same language.
Whatever the origin, that is the construction of a man. He is built in those three layers. With this analysis, it is perhaps easier to see how temptation may be met. Many a man goes through life hanging his head with shame and living without his self-respect because he has never discovered the distinction between temptation and sin. If he sees them coming and turns his back upon them, he has not sinned.
