720. What is the “intercessory prayer”?

The “intercessory prayer” is recorded in John 17. This is the great prayer that Jesus prayed prior to His passion. Here He prayed for the Apostles and for the future congregation, and thus also for us: “I do not pray for these alone, but also for those who will believe in Me through their word; that they all may be one...” (John 17: 20, 21).
