What does ancient prophecy say about the cross of Christ - the crucifixion of the Son of Man? Christ's death was a very great sacrifice for sins. What it did, Jesus said, was establish a new covenant ('in His blood'). So to find prophecies about it from before it happened we are looking for prophecies of a new covenant. We have the prophetic teachings of John the Baptist too for comparison and confirmation. The obvious text is 'this is My covenant with them when I take away their sins'. So we can compare this with John the Baptist's great prophecy 'Behold the Lamb of God which takes away the sins of the world'. So the prophecies show Jesus established by His crucifixion a covenant where sins are not merely forgiven (repentance could result in forgiveness before the death of Jesus) but TAKEN AWAY, eradicated. So by this new covenant sin is not just repented of by the life is freed from its hold and a saint is made.
