What does it mean that Christ is our sanctification?

When we say that Christ is our sanctification, we acknowledge that it is through Him we are made holy (1 Corinthians 1:30). This means that in addition to being our righteousness, He actively works within us to set us apart for God’s purposes. As we are born again, the Holy Spirit begins to dwell within us, empowering us to live according to God’s will. This process is ongoing; believers will continue to grow in holiness throughout their lives as they rely on Christ. Moreover, understanding that we are sanctified in Christ assures us that our failures do not diminish our standing before God. Our holiness is rooted in Christ's perfection, freeing us to pursue holiness in our daily lives without the fear of losing acceptance before God.
