The High-Priestly prayer of John 17 is one of the most wonderful and exciting portions of Scripture. As we read it we 'intrude' on a monologue directed by God the Son to God the Father. Few of Christ's prayer have been recorded for us and this is the longest - infact it is the longest prayer in the New Testament. It was spoken at a critical time, marking the end of the earthly ministry of Jesus and looked forward to the spread of the Gospel throughout the world by the apostles and their successors. As Ian McNaughton demonstrates in this thorough examination of the key doctrines and come to the fore in the prayer, John 17 take us to the very heart of the Christian faith and to who Jesus Christ really was.
