What does it mean to be sanctified by grace?

Sanctification is the process by which believers are made holy, ultimately conforming us to the image of Christ. This is a work initiated by the grace of God, where the Holy Spirit empowers believers to grow in holiness and righteousness. 1 Thessalonians 5:23-24 highlights God's faithfulness in this process, showing that He who calls us will also sanctify us completely. As we live out our faith, relying on God's grace, we become progressively more like Christ, reflecting His character in our lives.
