Look at Isaiah 53
There’s no way to sidestep the fact that the doctrine of penal substitution is unequivocally affirmed in the plain message of Isaiah 53. It is also confirmed and reiterated by many other passages throughout Scripture*. The servant of Yahweh, though perfectly innocent, bore the guilt of others and suffered unspeakable anguish to atone for their sins.
2 Corinthians 5:21: God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.
Galatians 3:13: Christ redeemed us from the curse of the law by becoming a curse for us, for it is written: “Cursed is everyone who is hung on a pole.”
Hebrews 9:28: So Christ was sacrificed once to take away the sins of many; and he will appear a second time, not to bear sin, but to bring salvation to those who are waiting for him.
1 Peter 2:24: “He himself bore our sins” in his body on the cross, so that we might die to sins and live for righteousness; “by his wounds you have been healed.”
