Father, Son and Holy Spirit
Justification and sanctification both stand on a threefold basis: In Romans we are justified by the grace of God, by the blood of Christ, and by faith, the operation of the Spirit (Rom. 3:24; 5:1-9).
In Hebrews we are sanctified by the will of God, the work of Christ, of which the Spirit is the witness (Heb. 10).
Righteousness and sanctification are both the combined work of Father, Son and Holy Spirit. The Father's will and grace gave the Son, the Son's blood and work accomplished our redemption, and faith and the witness of the Spirit cause us to accept this work. Young Christian
