Jn 1:29, Mt 8:16-17, Gal 3:13, 1 Pt 2:24, 1 Cor 15:3, 2 Cor 5:21, Rom 5:6-10, 1 Pt 3:18

In the Old Testament, Isaiah prophesied that the coming Christ would suffer and die to pay for our sins and save us. (Isa 53:4-6)

Isa 53:4 Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted. 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. 6 All we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on him the iniquity of us all.

As the Old Testament prophesied, Jesus bore the sins and sufferings of the world. (John 1:29, Matthew 8:16-17)

John 1:29 The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world.

Matthew 8:16 When the even was come, they brought unto him many that were possessed with devils: and he cast out the spirits with his word, and healed all that were sick: 17 That it might be fulfilled which was spoken by Esaias the prophet, saying, Himself took our infirmities, and bare our sicknesses.

Jesus took our sins and died on the cross to save us according to the prophecies of the Old Testament. (Gal 3:13, 1 Pet 2:24, 1 Cor 15:3, 2 Cor 5:21, Romans 5:6-10, 1 Pet 3:18)

Gal 3:13 Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree:

1 Pet 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.

1 Cor 15:3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures;

2 Cor 5:21 For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him.

Romans 5:6 For when we were yet without strength, in due time Christ died for the ungodly. 7 For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die. 8 But God commendeth his love toward us, in that, while we were yet sinners, Christ died for us. 9 Much more then, being now justified by his blood, we shall be saved from wrath through him. 10 For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life.

1 Pet 3:18 For Christ also hath once suffered for sins, the just for the unjust, that he might bring us to God, being put to death in the flesh, but quickened by the Spirit:
