Question: Was there any other way for God to forgive our sins besides the Cross? If there was, why didn’t He use it—or did He?
Answer: No, there was not. You know the scriptures: “I [Jesus] am the way, the truth, and the life: no man cometh unto the Father, but by me” (Jn:14:6); “Neither is there salvation in any other: for there is none other name under heaven given among men, whereby we must be saved” (Acts:4:12); “How shall we escape, if we neglect so great salvation...” (Heb:2:3); “the gospel of Christ...is the power of God unto salvation to every one that believeth” (Rom:1:16), etc.
In the Garden, Christ pleaded with His Father: “If it be possible [for man to be saved any other way], let this cup [i.e., the Cross] pass from me” (Mt 26:39). The answer was “No, there is no other way.”
We have broken the law of our infinitely holy Creator. The penalty for sin is separation from Him in eternal torment. He cannot compromise His justice without condoning our sin, thereby breaking His own law and becoming as guilty as we are.
There was only one way that God “might be just” and yet justify sinners (Rom:3:26): the penalty must be paid in full. Only Christ, who is both infinite God and man, could pay that penalty for mankind. And He did. Salvation is a gift of God’s grace to all who believe on and by faith receive the Lord Jesus Christ as personal Savior. There is no other way—nor could there be.
