What does John 17:26 mean?
The end of Jesus' High Priestly Prayer (John 17:1) ties together many of the themes on which He has prayed.Christ's life, teachings, and miracles demonstrated the will of God the Father (John 10:25, 37–38; 17:4, 6). In this way, He presented "the name" of God—meaning God's authority, power, and nature—to humanity (Hebrews 1:3). To this point in His earthly life, Jesus has fulfilled that mission from God. He has said, done, and acted exactly as God the Father wills (John 5:30).
The context of Jesus' prayer is His impending arrest, torture, and execution (John 18:1–3). Even through this experience, He will continue to speak and act only according to the will of God (Matthew 26:53; Mark 14:61–62; Luke 22:42; John 18:37). This was, in fact, part of His purpose in being sent by God the Father (John 12:32–33).
A major theme of Jesus' teaching on the night of His arrest was godly love. This concept of love, in fact, is meant to be the hallmark of Christian faith (John 13:34–35; 17:21). That love leads to unity (Colossians 3:14), grounded in sincere obedience to Christ (John 14:15), demonstrating His truth to the world (Matthew 5:13–16).
Following this prayer, Jesus will cross into Gethsemane and continue to pray (Matthew 26:36–46). Those details, John leaves to Matthew, Mark, and Luke.
