In verse 9 Jesus assumes the great office of Intercessor. 'I pray for them' is not so much prayer as His solemn presentation of Himself before the Father as the High-priest of His people. It marks an epoch in His work. The task of bringing God to man is substantially complete. That of bringing men by supplication to God is now to begin. It is the revelation of the permanent office of the departed Lord. Moses on the Mount holds up the rod, and Israel prevails (Exod. xvii. 9). The limitation of this prayer to the disciples applies only to the special occasion, and has no bearing on the sweep of His redeeming purpose or the desires of His all-pitying heart. The reasons for His intercession follow in verses 9-11a. The disciples are the Father's, and continue so even when 'given' to Christ, in accordance with the community of possession, which oneness of nature and perfectness of love establish between the Father and the Son. God cannot but care for those who are His. The Son cannot but pray for those who are His. Their having recognised Him for what He was binds Him to pray for them. He is glorified in disciples, and if we show forth His character, He will be our Advocate. The last reason for His prayer is the loneliness of the disciples and their exposure in the world without Him. His departure impelled Him to Intercede, both as being a leaving them defenceless and as being an entrance into the heavenly state of communion with the Father. In the petition itself (v. 11b), observe the invocation 'Holy Father!' with special reference to the prayer for preservation from the corruption of the world. God's holiness is the pledge that He will make us holy, since He is 'Father' as well. Observe the substance of the request, that the disciples should be kept, as in a fortress, within the enclosing circle of the name which God has given to Jesus. The name is the manifestation of the divine nature. It was given to Jesus, inasmuch as He, 'the Word,' had from the beginning the office of revealing God; and that which was spoken of the Angel of the Covenant is true in highest reality of Jesus: 'My name is in Him.' 'The name of the Lord is a strong tower: the righteous runneth into it and is safe.' Observe the issue of this keeping; namely, the unity of believers. The depths of that saying are beyond us, but we can at least see thus far--that the true bond of unity is the name in which all who are one are kept; that the pattern of the true unity of believers is the ineffable union of Father and Son, which is oneness of will and nature, along with distinctness of persons; and that therefore this purpose goes far deeper than outward unity of organisation.
