The sacrifice of Christ was not all made on the cross. The purpose was formed before man existed; for Christ is “the Lamb slain from the foundation of the world.” (See Rev. 13:8; 1 Peter 1:19, 20.) The cost was all counted there; the purpose was formed, to be developed by the later ages. Neither did his work for man begin when the Son of God came to this earth; it began when man was totally depraved and willingly, completely under the power of sin. While sin incarnate, sin in the flesh, is enmity toward God, God implanted in the heart of the natural man enmity toward Satan and sin. (Gen. 3:15.) Tho a slave of sin, man possesses conscience and will and power of choice. Tho in himself “without strength,” he may connect with Him in whom is all power. Tho in himself4and of himself is the darkness of sin, yet, through the implanted enmity to sin, Christ “lighteth every man that cometh into the world.” (John 1:9.) Through that enmity to sin, that love of God, God appeals to every soul, by his works in nature, by his word, by his Spirit, by those whom the Spirit has redeemed. But man must choose, either the service of the evil that enchains him, with the certain death to follow, or the service of Christ, and the victory, liberty, and life that are in him.
