How do we know that Christ is our sanctification?

According to 1 Corinthians 1:30, Christ is our sanctification, a truth that significantly impacts how we understand our standing before God. This perspective aligns with the doctrine of sovereign grace, emphasizing that sanctification is not merely a work we perform but a status conferred upon us through our union with Christ. As believers, we grow in grace and knowledge, but such growth is rooted in the truth that Christ is the source of our holiness. By acknowledging Christ as our sanctification, we understand that we rely entirely on His accomplished work for our spiritual growth, rather than attempting to achieve holiness through our efforts.
