His Grace
The grace that we need for our sanctification is indeed the grace of God. But it is the grace of God in and through his Son, Jesus Christ, by the grace of the Holy Spirit (2 Cor. 13:14). In other words, whatever grace we receive for our holiness first belonged to the Savior (John 1:16). As the resurrected Lord of the new creation, Christ has exclusive right to this prerogative (Col. 1).
