Cain and Abel represent two classes that will exist in the world till the close of time. One class avail themselves of the appointed sacrifice for sin; the other venture to depend upon their own merits; theirs is a sacrifice without the virtue of divine mediation, and thus it is not able to bring man into favor with God. It is only through the merits of Jesus that our transgressions can be pardoned. Those who feel no need of the blood of Christ, who feel that without divine grace they can by their own works secure the approval of God, are making the same mistake as did Cain. If they do not accept the cleansing blood, they are under condemnation. There is no other provision made whereby they can be released from the thralldom of sin.
The class of worshipers who follow the example of Cain includes by far the greater portion of the world; for nearly every false religion has been based on the same principle—that man can depend upon his own efforts for salvation. It is claimed by some that the human race is in need, not of redemption, but of development—that it can refine, elevate, and regenerate itself. As Cain thought to secure the divine favor by an offering that lacked the blood of a sacrifice, so do these expect to exalt humanity to the divine standard, independent of the atonement. The history of Cain shows what must be the results. It shows what man will become apart from Christ. Humanity has no power to regenerate itself. It does not tend upward, toward the divine, but downward, toward the satanic. Christ is our only hope. “There is none other name under heaven given among men, whereby we must be saved.” “Neither is there salvation in any other.” Acts 4:12.
True faith, which relies wholly upon Christ, will be manifested by obedience to all the requirements of God. From Adam’s day to the present time the great controversy has been concerning obedience to God’s law. In all ages there have been those who claimed a right to the favor of God even while they were disregarding some of His commands. But the Scriptures declare that by works is “faith made perfect;” and that, without the works of obedience, faith “is dead.” James 2:22, 17. He that professes to know God, “and keepeth not His commandments, is a liar, and the truth is not in him.” 1 John 2:4
