Imputation

Pastor Martin moves from the Gospels into the period of explanation and application, demonstrating that the apostolic epistles continue to assert Christ's true humanity as essential to the gospel. He surveys Romans 1, Romans 9, 1 Corinthians 15, Galatians 4, 1 Timothy 2, and Hebrews 2 to show that Paul and the writer to the Hebrews never blush to call Jesus a man. He then applies the doctrine, showing that Christ's humanity authenticates him as the promised Messiah and equips him as an efficient mediator who could establish legal union with sinners, obey the law in their stead, and suffer the curse for their sins.

Pastor Martin completes his exposition of the essence of Christ's sacrifice with the words 'penal' and 'satisfaction.' He explains that Christ's sufferings were not merely calamity or chastisement but legal punishment that fully met the demands of God's law against sin. Drawing on the triangular realities of the nature of the law, the nature of God, and the nature of man, he shows from Galatians 3:13, Deuteronomy 21:22-23, and Colossians 2:14 that Christ bore the curse of the law as the God-man, and he closes with John Owen's beautiful imagery of the sinner as Noah's dove finding rest only in the ark of Christ.

Using the Westminster Larger Catechism's definition as a teaching framework, Pastor Martin opens up the first three elements of justification: God Himself is its author, His free grace its source, and sinners as sinners (not half-reformed sinners) are its objects. He illustrates with a vivid scenario of a condemned criminal receiving a reprieve and presses the parable of the publican and the Pharisee to show that God justifies the ungodly the moment he casts himself on mercy, not after any reformation.

Pastor Martin opens the second negative of the Larger Catechism: the ground of justification is not anything wrought in us by the gracious work of the Spirit. He acknowledges that God always sanctifies whom He justifies, but insists that nothing of that internal work - new heart, new affections, repentance, growing holiness - forms any part of the legal ground of justification. The righteousness justifying us is a God-righteousness in Christ, external to us, received only by faith.

Pastor Martin opens up the biblical concept of imputation - the charging or reckoning of one's account to another - as the very fabric of the doctrine of sin and salvation. He traces the word's general usage in Leviticus, 2 Samuel, Psalm 32, Romans 4, and Philemon, then sets out the three great imputations: Adam's sin imputed to the race, the sins of God's people imputed to Christ, and the righteousness of Christ imputed to believers. The basis of all three is federal headship and covenant union.
