I placed this on the forum several years ago. It represents my thinking on the subject of Penal Substitution. I also wrote an article on P.S. and the Trinity, which I will reproduce if anyone is interested.
Isaiah 53:6. ‘We all like sheep have gone astray; we have turned, every one, into his own way; and the LORD has laid on Him the iniquity of us all.’
Galatians 3:13. ‘Christ has redeemed us from the curse of the law, having become a curse for us.’
First, a definition: ‘The doctrine of Penal Substitution states that God gave Himself in the Person of His Son to suffer instead of us the death, punishment and curse due to fallen humanity as the penalty of sin’ (Pierced for our Transgressions: Rediscovering the Glory of Penal Substitution by Jeffrey, Ovey and Sach. IVP. ISBN 978-1-84474-178-6).
The doctrine of Penal Substitution has encountered much opposition over the last several years. Having debated it extensively on a discussion forum recently, I thought it would be a good idea to write my thoughts out in depth and present them here. The temptation is simply to quote Isaiah 53:5-6 and finish there since these verses seem perfectly clear and comprehensive to me. However, since more evidence seems to be required, I give it below. This is quite a long post but I make no apology for that; the doctrine is so vital for the proper understanding of the Christian faith that it is worth spending some time upon it.
Penal Substitution is rooted in the character of God as He revealed Himself to Moses in Exodus 34:6-7. “The LORD, the LORD God, merciful and gracious, longsuffering, and abounding with goodness and truth, keeping mercy for thousands, forgiving iniquity and transgression and sin, by no means clearing the guilty.” Immediately the question arises, how can God be merciful and gracious, how can He forgive iniquity, transgression and sin without clearing the guilty? How can He clear the guilty if He abounds with truth—if He is a ‘just Judge’ (Psalm 7:11)? How can it be said that, ‘Mercy and truth have met together; righteousness and peace have kissed’ unless God can simultaneously punish sin and forgive sinners? The answer is that ‘God……devises means, so that His banished ones are not expelled from Him’ (2 Samuel 14:14). Those means are Penal Substitution. “Learn ye, my friends, to look upon God as being as severe in His justice as if He were not loving, and yet as loving as if He were not severe. His love does not diminish His justice nor does His justice, in the least degree, make warfare upon His love. The two are sweetly linked together in the atonement of Christ” (C.H. Spurgeon).
Right at the start of the Bible (Genesis 2:16-17) we have a direct command to Adam, Adam, the ‘first man’ (1 Corinthians 15:47): ‘And the LORD God commanded the man, saying, “Of every tree in the garden you may freely eat, but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall surely die.”’ The command is accompanied by a penal sanction– death. Yet we know that in the Bible death is not restricted to simply the end of existence. ‘….It is appointed to men to die once, but after this the judgement’ (Hebrews 9:27).
In Genesis 1:28, we see that God blessed His creation; marriage, child-bearing and work are specifically mentioned in that verse as part of this blessing. But at the Fall in Genesis 3, the blessings are turned to curses. Childbirth is marked by pain, the marriage bond is marred, and work becomes hardship and struggle, with death as the final inevitable result (Genesis 3:16-19). These are penal sanctions by God; they are His righteous response to sin. Sinful men and women are not going to live in a perfect environment; every aspect of it has been marred by sin. ‘For the whole creation was subjected to futility, not willingly, but because of Him who subjected it in hope’ (Romans 8:20).
So both our lives and our deaths are subject to the curse because of sin. We learn from Romans 5 that Adam was our federal head—what he did, we have done in him. Therefore just as through one man sin entered the world, and death through sin, and thus death spread to all men because all sinned…..’ (v.12). God’s curse extends to mankind because we are every one of us sinners (e.g. 2 Chronicles 6:36). We read in Psalm 7:11 that ‘God is a just Judge [therefore whomever God punishes for sin must be guilty of sin], and God is angry with sinners every day,’ and in Proverbs 17:15 we learn that ‘he who justifies the wicked, and he who condemns the just, both of them alike are an abomination to God.’
So we come to the necessity of Atonement. We must be very careful in saying that God cannot do something, but the Scriptures tell us that God ‘cannot deny Himself’ (2 Timothy 2:13). In the light of Proverbs 17:15, God surely cannot become an abomination to Himself by justifying guilty sinners without a penalty for sin! Be it said that God is under no obligation to show mercy to sinful humans; the angels who sinned had no Redeemer but were ‘cast down to hell and delivered into chains of darkness, to be reserved for judgement’ (2 Peter 2:4). But if God, ‘according to the good pleasure of His will’ (Ephesians 1:5), has decreed mercy and salvation for certain sinful men and women, it surely cannot be at the expense of His justice. Someone must pay the price and satisfy God’s justice and His righteous anger against sin.
In the Scriptures we have the concept of the mediator, one who might fill up the gap between the outraged holiness of God and rebellious man (Isaiah 59:2). Job complained, “For He is not a man, as I am, that I should answer Him, and that we should go to court together. Nor is there any mediator between us who may lay his hand on us both.” But mediation requires a satisfaction to be made to the offended party. We see this is the book of Philemon. Here we have an offended party, Philemon, whose servant has run away from him, perhaps stealing some goods as he went; an offending party, Onesimus, and Paul who is attempting to mediate between them. Onesimus needs to return to his master, but fears the sanctions that may be imposed upon him if he does so. Paul takes these sanctions upon himself: ‘But if he has wronged you or owes anything, put that on my account. I, Paul, am writing with my own hand. I will repay…..’ (Philemon 18-19). Whatever is wanting to propitiate Philemon’s anger against his servant and to effect reconciliation, Paul the mediator willingly agrees to provide. In the same way, the Lord Jesus has become a Mediator between men and God (1 Timothy 2:5).
In 2 Corinthians 5:19, we learn that God does not impute trespasses against His people; in Christ; He has reconciled the world [believing Jew and Gentile alike] to Himself. How has He done this? Through the Mediator Jesus Christ. ‘For He made Him who knew no sin to be sin for us….’ (v.21). The Lord Jesus has taken our sins upon Himself and made satisfaction to God for them. Therefore the message of reconciliation can be preached to all.
A similar concept is that of a surety. This is someone who guarantees the debts of a friend and must pay them in full if the friend defaults. There are several warnings in the Book of Proverbs against becoming a surety (Proverbs 6:1-5; 11:15; 17:18), since one is making the debts of one’s friend effectively one’s own, yet we read in Hebrews 7:22, ‘By so much more Jesus has become a surety of a better covenant.’ More on that verse presently.
In the Old Testament, animal sacrifices were made to God for the sins of the people. We read over and over again that creatures to be offered had to be without blemish (Leviticus 1:3 etc., etc.). ‘It must be perfect to be accepted; there shall be no defect in it’ (Leviticus 22:21). Given that He is the fulfilment of the O.T. sacrifices (Hebrews 9:11-15 etc.), the physical perfections of the sacrificed animals speak of the moral and spiritual perfections of Christ. 1 Peter 1:18-19 speaks of ‘….the precious blood of Christ as of a lamb without blemish and without spot.’ So it was necessary for the Lord Jesus to live the life that Adam failed to live– the life of perfect obedience to the Father’s will (Psalm 40:8). And this ‘Active Obedience’ is not a notional thing; it had to be lived out in the most practical way. Hence, ‘immediately’ after His baptism, ‘the Spirit drove Him into the wilderness’ (Mark 1:12-13) for an encounter with Satan. He must succeed where Adam fell.
God’s law makes two inexorable demands: ‘Do this and live’ (Leviticus 18:5; Galatians 3:12), and ‘The soul that sins shall die’ (Ezekiel 18:4). The first demand our Lord has met in His perfect obedience. He was made ‘under the law’ (Galatians 4:4) and fulfilled it (Matthew 5:17). His obedience has been placed to the credit of His people (Romans 5:19) and they are now made ‘the righteousness of God in Him’ (2 Corinthians 5:21).
For the second demand, we need to look again at Hebrews 7:22: ‘By so much more Jesus has become a surety of a better covenant.’ Christ is specifically designated in Scripture as ‘the last Adam’ (1 Corinthians 15:45) and we are told that the first Adam was a ‘type [or ‘figure’] of Him who was to come’ (Romans 5:14). ‘For as in Adam all die, even so in Christ all shall be made alive’ (1 Corinthians 15:22). All those in Adam perish in their sins; all those in Christ are united to Him in His perfect righteousness.
