And this great result, — a result on which depends union or separation, life or death, happiness or woe, — is made to turn upon his own free choice. It is not left to him, however, to choose a mixed or middle course. And the reason is that there is no such course. "Ye cannot serve God and mammon." There can be but one true life, and that is life from God. Our heavenly Father, dwelling in man as the Divine Teacher or Comforter, must be the whole, the true life and the whole life in us or he can be nothing. And this is a matter, which, as a moral agent, man is called upon to decide for himself; — namely, whether God, without dividing his influence with any other master or teacher, shall be his inward life, and thus be, in all coming time, the inspiration and source of all good. This choice is given him in Christ. If he accepts God, he lives. If he rejects him, he dies.
