To create, God had but to speak, and it was done. But to redeem, He had to bleed. And He did so in the Person of His Son, Jesus Christ, whom He sent to take the place of death upon the cross which our sin had so richly deserved.
Redemption, however, was no last-minute thought, brought into being to meet an unexpected emergency. No sooner had sin entered the garden than God spoke of One who was to come and who was to bruise the serpent’s (that is, Satan’s) head, His own heel being bruised in the process (Genesis:3:15), and to restore all the damage which sin and Satan had done.
God thereby revealed that the sad turn of events had not taken Him by surprise, but that there was One in reserve to meet this very situation. Scripture calls Him “the Lamb slain from the foundation of the world” (Revelation:13:8), because with God the remedy antedated the disease. And all this was done with the one purpose of bringing us fallen men with our sinful, proud, unbroken natures back to that relationship with God of submissiveness and God-centeredness that was lost in the Fall—that position where once more He can delight in us and we in Him.
