Messiah's sacrifice would bring reconciliation between man and God

Isa:53:5: But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.

Col:1:20: And, having made peace through the blood of his cross, by him to reconcile all things unto himself; by him, I say, whether they be things in earth, or things in heaven.

1Pe:2:24: 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.

As you can see Isaiah prophesized that there would be a messiah (Jesus) and he would come down and offer all of humanity salvation. That all we have to do is take it. In Col:1:20 the words are slightly different than those used by Isaiah, however the message is identical. This message is that, through the blood on the cross which Jesus shed for us, all things have been repaired and we may have salvation and enter into the kingdom of Heaven through faith. Isaiah somehow KNEW that the Lord Jesus would come as man and that He would be beaten and His blood would be shed so that we could experience the peace and unconditional love for eternity that was only possible through this belief.
