God calls us as His people to pursue sanctification in the totality of our lives. Holiness is one of our greatest needs in the Christian life. However, we often fail to understand what part God plays in our sanctification. In this lesson, Dr. Charles breaks down the benediction in 1 Thessalonians 5:23–24 in order to stress the fact that our sanctification is built on the confidence that God is the One who sanctifies believers as we trust Him for this work of grace.
