Why does Jesus pray for our sanctification?

Sanctification is a critical aspect of the Christian life, and Jesus emphasizes this in His prayer by asking the Father to sanctify us through the truth, identifying His Word as that truth (John 17:17). His desire is that we be set apart for God’s purposes—cleaned from sin and equipped for holy living. This request for sanctification indicates that our growth in Christ-likeness is a vital part of His intercessory work. It highlights that God not only saves us but also transforms us for His glory. Understanding this helps believers recognize that the sanctifying work of the Holy Spirit, as empowered by Christ’s ongoing prayers, is essential for living in obedience and reflecting God’s character.
