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. 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. True faith, which relies wholly upon Christ, will be manifested by obedience to all the requirements of God.
