Your sins didn’t cause His death. He came before the Universe was created to be the the Passover Sacrifice. G-d knew what he was doing. Ponder that.
Christ died for our sins. He tells us that in Scripture.
From what you are saying it seems to me that you are saying Christ is NOT the redeemer?
Is that correct?
Wrong. Death entered the human race when Adam sinned. Not only was Christ free from the stain of sin from Adam, he led a sinless life. Therefore Christ was the new Adam and as such, immortal. Had he not accepted our sins to be the sacrifice for us he not only wouldn't have died, he couldn't have died.
