Why is the high priestly prayer of Jesus important for Christians?

The high priestly prayer of Jesus in John 17 is significant because it illustrates His role as intercessor, voicing profound requests to the Father on behalf of His followers. In this prayer, Jesus makes several demands, including requests for glory, protection, salvation of believers, and a promise that His followers will be with Him eternally. These claims not only affirm the assurance of their salvation but also emphasize that Christ actively intercedes for them before the Father. This prayer gives believers tremendous comfort, reinforcing that their standing before God is secure because of Christ's mediation and His commitment to saving and keeping His people.
