I was waiting for JonC to get onto the New Testament before replying, but since he hasn't done so, here goes:
Isaiah 53 tells us of Jesus and His sufferings. He was a man of sorrows, despised by those around Him. But He bore our griefs and sorrows. The people considered Him as stricken and smitten of God and afflicted, however He was pierced for our transgressions, crushed for our iniquities. The chastening for our well-being fell upon Him and by His scourging we were healed. All of us have gone astray, but God has caused the iniquity of us all to fall on Him.
Of course the people were right; He was stricken and smitten by God.
'Yet it pleased the LORD to bruise Him; He has put Him to grief,' confirmed by Zech. 13:7; Matt. 26:31, 56. Where they were wrong was in supposing that He was wounded for His own transgressions.
He was oppressed and afflicted, but He did not open His mouth. By oppression and judgment He was taken away. He was killed for the transgressions of the people, who had earned death. God was pleased to crush Him, putting Him to grief, that if He would render Himself as a guilt offering He will see the fruits of His work and He will justify the many as He bore their iniquities.
Exactly. He was killed for the transgressions of others. Penal Substitution.
Psalm 22 foreshadows the Cross. This psalm begins “My God, My God, why have You forsaken Me? Far from my deliverance are the words of my groaning”. The picture is God’s Servant suffering while deliverance has not yet come. The Servant then turns to God’s faithfulness. He knows that God will never abandon Him. Instead God will deliver Him. The Servant appeals to God’s faithfulness to His forefathers as they were forsaken to suffer. He appeals to God’s own character. Those who trust in the Lord will not be disappointed. Towards the end of the psalm we see that God has not despised the Servant, nor has He hidden His face. When He cried for Help God heard.
The servant confirms that it is God who has brought Him to the dust of death (v.15). He cries out to God, but for a time God has forsaken Him and does not answer (vs. 1-2). The reason for this is that He was made sin for us, and God's eyes are too pure the behold evil (Hab. 2:13). But at the ninth hour, the Lord Jesus cried out quoting this very psalm and the Father heard Him. Jesus could cry out,
"It is finished!" And then commit His spirit to God (Luke 23:46).
'Therefore [God] will divide Him a portion with the great [c.f. Phil. 2:9]
, and He shall divide the spoil with the strong, because He poured out His soul unto death, and He was numbered with the transgressors.'
Psalm 4 speaks of God answering when the righteous call out in destress. God hears when they call.
So, at the 9th hour, after propitiation has been made, He answers the cry of the Lord Jesus.
Deuteronomy 15 describes justice as justifying the righteous and condemning the wicked.
Psalm 37 tells us that God will never abandon or condemn the just.
Proverbs 12 tells us that the righteous will obtain favor but God will condemn the evil man.
Proverbs 17 tells us that one who justifies the wicked and one who condemns the righteous are both abominations to God.
I suppose that these texts are supposed to show that God could not condemn the Lord Jesus. But as Isaiah 53:10 and Zech. 13:7 show, that is exactly what He did. I suppose that this is the issue that we need to thresh out.
I believe the reasons are two-fold: firstly, God does not take some random bloke and lay the sins of the world upon him. It is God Himself in the Person of Jesus Christ who will make propitiation for sin. Secondly, Christ was made sin for us (2 Cor. 5:21). That does not mean that He was made a sinner, but it does mean that our sins were laid upon Him and He bore them and the curse attached to them.
Ezekiel 18 teaches us that the person who sins will be accountable for their sin. Sins cannot pass from one person to another. If a man lives righteously but then repents of good and does evil then he will be held guilty. But if a man does evil and repents of that evil then God is faithful to forgive. God takes no pleasure in the death of the wicked, but instead wants that he should turn from wickedness and live. Rebellious men will object and say “the way of the Lord is not right”. But it is their ways that is not right. They view sins as transferrable, and they reject God’s declaration that should one repent He will be faithful to forgive. Therefore God will judge them by their own conduct. God declares that they should repent and turn away from all of their transgressions so that iniquity may not become a stumbling block to them. He takes no pleasure in the death of anyone. Therefore, repent and live.
No need for Jesus Christ then. Salvation by works!
A text like this should drive us to despair.
'Therefore by the deeds of the law no flesh will be justified in His sight, for by the law is the knowledge of sin.' But
'Therefore the law was our tutor to bring us to Christ that we might be justified by faith.'
