In John 17:17, on the night before the cross, Jesus prays for his disciples—and for all who would believe through their word—asking the Father to “sanctify them in the truth; your word is truth.” This sermon explores what it means to be set apart from the world and sin, and set apart for God and his service, through the truth of Scripture. We will see how Christ’s effective intercession keeps us from falling, fills us with his joy, guards us from the world and the devil, unites us with one another and with God, causes us to share in his glory, and makes us faithful witnesses. Take comfort in the prayer of our Savior who still prays for his people.
