Jesus died for the sins of all mankind but He did not serve as a punishment substitute for those sins. Your error is in viewing "Jesus dying for sin" in the context of a "substitution."
There was and is no exchange. You don't swap places with Jesus and Jesus does not swap places with you.
Jesus died on your behalf so that you would follow His example and die too.
What did Jesus say?
Luk 9:22 Saying, The Son of man must suffer many things, and be rejected of the elders and chief priests and scribes, and be slain, and be raised the third day.
Luk 9:23 And he said to them all, If any man will come after me, let him deny himself, and take up his cross daily, and follow me.
Luk 9:24 For whosoever will save his life shall lose it: but whosoever will lose his life for my sake, the same shall save it.
Does that sound like a substitution to you?
Jesus was not your substitute, He was your EXAMPLE.
1Pe 2:21 For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps:
1Pe 2:22 Who did no sin, neither was guile found in his mouth:
1Pe 2:23 Who, when he was reviled, reviled not again; when he suffered, he threatened not; but committed himself to him that judgeth righteously:
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.
Is Peter teaching substitution there?
Is Paul teaching substitution in Romans 6?
Rom 6:3 Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
Rom 6:4 Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
Rom 6:5 For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
Rom 6:6 Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
Rom 6:7 For he that is dead is freed from sin.
Redemption is via DEATH AND REBIRTH. We die WITH Christ and we are raised WITH Christ. Not in position but in REALITY.
The cross is the means by which God deals with the root of iniquity in the heart of a sinner. The root of sin is destroyed once and for all. Paul personifies it as the "body of sin" which is DESTROYED from which the "service of sin" ceases.
This is why Peter would say...
1Pe 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:
...
1Pe 4:1 Forasmuch then as Christ hath suffered for us in the flesh, arm yourselves likewise with the same mind: for he that hath suffered in the flesh hath ceased from sin;
1Pe 4:2 That he no longer should live the rest of his time in the flesh to the lusts of men, but to the will of God.
Being put to death in the flesh is a picture of our old man being crucified in repentance whereby we no longer walk according to the lusts of the flesh. Instead of being driven like base animals we keep ourselves by the Spirit of God in which we abide. We are regenerated from the carnality in which we walked according to our own lusts unto the Spirit filled life where we walk according to the will of God. Salvation is a PRESENT MANIFEST STATE not some position that comes into effect due to some substitutionary legal swap.
Jason I quote you the Bible and you ignore it. Look at your posts about substitution, it is pure rhetoric and conjecture. You completely ignore what the Book of Hebrews teaches. Jesus had to die to bring in the New Covenant because God has ordained that His covenants are sealed by blood. That is why we have the blood of the covenant. Jesus preached the Ministry of Reconciliation to sinners and then sealed His ministry with His death. Jesus put an end to any notion of "law keeping" and preached about the SOURCE of righteousness which is FAITH WHICH WORKS BY LOVE. True righteousness is not via keeping rules and regulations, it is via walking in the same Spirit which Jesus walked in. In other words we are to ABIDE IN THE SPIRIT OF LIFE.
