How does Christ being all relate to sanctification?

Sanctification is the process by which believers are made holy, and it is only through Christ that this transformation occurs. According to Hebrews 10:14, He has perfected forever those who are sanctified, illustrating that our holiness is achieved through Him alone. As we grow in knowledge and faith, we increasingly embody the truth that 'Christ is all,' leading to a life that reflects His likeness. The believer's journey is not one of striving in self-effort but resting in Christ, who empowers us by His Spirit to live out His righteousness. Hence, our sanctification is not a work of the flesh but a continual reliance on His grace and strength.
