John 17:16-19 give the final petition for the immediate circle of disciples, with its grounds. The position of alienation from the world, in which the disciples stand by reason of their assimilation to Jesus, is repeated here. It was the reason for the former prayer, keep'; it is the reason for the new petition, sanctify.' Keeping comes first, and then sanctifying, or consecration. Security from evil is given that we may be wholly devoted to the service of God. The evil in the world is the great hindrance to that. The likeness to Jesus is the great ground of hope that we shall be truly consecrated. We are kept' in the name'; we are consecrated in the truth,' which is the revelation made by Jesus, and in a very deep sense is Himself. That truth is, as it were, the element in which the believer lives, and by abiding in which his real consecration is possible.
Christ's prayer for us should be our aim and deepest desire for ourselves, and His declaration of the condition of its fulfilment should prescribe our firm adhesion to, and constant abiding in, the truth as revealed and embodied in Him, as the only means by which we can attain the consecration which is at once, as the closing verses of the passage tell us, the means by which we may fulfil the purpose for which we are sent into the world, and the path on which we reach complete assimilation to His perfect self-surrender. All Christians are sent into the world by Jesus, as Jesus was sent by the Father. We have the charge to glorify Him. We have the presence of the Sender with us, the sent. We are inspired with His Spirit. We cannot do His work without that entire consecration which shall copy His devotion to the Father and eager swiftness to do His will. How can such ennobling and exalted consecration be ours? There is but one way. He has consecrated Himself,' and by union with Him through faith, our selfishness may be subdued, and the Spirit of Christ may dwell in our hearts, to make us living sacrifices, consecrated and acceptable to God.' Then shall we be truly consecrated,' and titan only, when we can say, I live; yet not I, but Christ liveth in me.' That is the end of Christ's consecration of Himself--the prayer which He prayed for His disciples--and should be the aim which every disciple earnestly pursues.
