What is it that actually saves us from our sin?

What is it that actually saves us from our sin? Is it the sufferings of Christ alone?

Consider the following scriptures:

1 Peter 2:

Verse 21 Christ also suffered for us, leaving us an example, that ye should follow his steps: 22 Who did no sin, neither was guile found in his mouth: 23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously: 24 Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed.

So, Christ's sufferings alone cannot save us from our sin, it was the baring of our sins.

Consider these verses, which are from the great details of the "day of atonement", Leviticus ch.16:

Verse 20 ¶ And when he hath made an end of reconciling the holy place, and the tabernacle of the congregation, and the altar, he shall bring the live goat:

21 And Aaron shall lay both his hands upon the head of the live goat, and confess over him all the iniquities of the children of Israel, and all their transgressions in all their sins, putting them upon the head of the goat, and shall send him away by the hand of a fit man into the wilderness:

22 And the goat shall bear upon him all their iniquities unto a land not inhabited: and he shall let go the goat in the wilderness.

If Christ had suffered all that we read of in scripture (which He did), yet God had not laid our sins on Him, then there would have been no atonement, no hope of any forgiveness!
