“As we conclude, I submit that we do indeed find much good news in the Gospels by focusing on the life of Jesus unto salvation. As the last Adam, Jesus vicariously realizes the obedience necessary for eternal life, overcoming the problem of sin and death.
One would need many, many volumes to discuss the grace that is manifested to us through Jesus Christ; indeed, I suppose that the whole world would not be able to contain the books that could be written. I finish, then, with a few brief reflections on the wonders of the grace of Jesus Christ that is revealed in the Gospels.
In the Gospels we see that Jesus accomplishes the righteousness that characterizes the kingdom of God, and this righteousness is a gift. The kingdom demands a better righteousness than that of the scribes and Pharisees for those who would enter it (Matt. 5:20), yet it is also the Father’s good pleasure to grant the kingdom (Luke 12:32).
The stringency in entering the kingdom is ultimately answered by the full obedience of Jesus Himself, who establishes and opens the gates of the kingdom through His perfect obedience—both active and passive. Jesus shows us the unity of obedience and love that the covenantal law of God always required.
Jesus’s people, then, must be united to Him by faith, and so receive the blessings of salvation through the work of the last Adam. By following in the righteous steps of the Messiah, we learn how to truly love God and love our neighbor.
Jesus is definitively and representatively obedient as the last Adam and Son of God, and His people are obedient in a derivative sense, through faith in Him. Jesus is the mediator of the new covenant, which is sealed in His blood.
The full measure of the law has been met, and the penalty of sin has been overcome through Jesus’s death and resurrection. Our faith and hope must therefore be in Jesus Christ, who has proven obedient on our behalf.
I conclude with the confidence expressed by New Testament scholar J. Gresham Machen. As he lay dying in a North Dakota hospital, Machen’s last recorded words came via telegram: ‘I’m so thankful for the active obedience of Christ. No hope without it.’
Machen’s hope is gloriously narrated for us in the Fourfold Gospel, where we read of salvation accomplished by the fully obedient last Adam. As Jesus delighted to do His Father’s will, may we delight to trust in and follow a gracious Savior.”
