The Last Adam, also given as the Final Adam or the Ultimate Adam, is a title given to Jesus in the New Testament. Similar titles that also refer to Jesus include Second Adam and New Adam. John MacArthur equates the Last Adam with the Second Adam.
Twice in the New Testament an explicit comparison is made between Jesus and Adam. In Romans 5:12–21, Paul argues that "just as through the disobedience of the one man the many were made sinners, so also through the obedience of the one man the many will be made righteous" (Romans 5:19, NIV). In 1 Corinthians 15:22, Paul argues that "as in Adam all die, so in Christ all will be made alive," while in verse 45 he calls Jesus the "last/ultimate/final Adam".
John Henry Newman used the phrase "Second Adam" in his hymn "Praise to the Holiest in the height", first appearing in The Dream of Gerontius:
O loving wisdom of our God!
When all was sin and shame,
A second Adam to the fight
And to the rescue came.
The title "New Adam" is emphasised in the Recapitulation theory of atonement.
Paul the Apostle contrasted Adam and Christ as two corporate personalities or representatives (Rom 5:12–21; 1 Cor. 15:20–3, 45–9) and saw human beings as bearing the image of both Adam and Christ (1 Cor. 15:49). Where Adam's disobedience meant sin and death for all, Christ's obedience more than made good the harm due to Adam by bringing righteousness and abundance of grace (Rom 5:12–21). As a "life-giving spirit", the last Adam is risen from the dead and will transform us through resurrection into a heavenly, spiritual existence (1 Cor. 15:22, 45, 48–9). Thus Paul's Adam Christology involved both the earthly Jesus' obedience (Rom. 5) and the risen Christ's role as giver of the Spirit (1 Cor. 15).
