What role does Christ play in our sanctification?

In the process of sanctification, Christ serves as the meritorious cause. As articulated in Hebrews 10:10, we are sanctified through the offering of the body of Jesus Christ. This highlights that our sanctification is grounded in the sacrificial work of Christ, who set Himself apart to fulfill God's plan of redemption. In John 17:19, Christ states, 'For their sakes I sanctify myself,' indicating that His own consecration and devotion to His mission is intrinsically linked to the sanctification of believers. Thus, through His perfect obedience and sacrifice, He secures not only our justification but also our ongoing sanctification.
