The purpose of the petition is to be noted; namely, the Son's glorifying of the Father. No taint of selfishness corrupted His prayer. Not for Himself, but for men, did He desire His glory. He sought return to that serene and lofty seat, and the elevation of His limited manhood to the throne, not because He was wearied of earth or impatient of weakness, sorrows, or limitations, but that He might more fully manifest by that Glory, the Father's name. To make the Father known is to make the Father glorious; for He is all fair and lovely. That revelation of divine perfection, majesty, and sweetness was the end of Christ's earthly life, and is the end of His heavenly divine activity. He needs to reassume the prerogatives of which He needed to divest Himself, and both necessities have one end. He had to lay aside His garments and assume the form of a servant, that He might make God known; but, that revelation being complete, He must take His garments and sit down again, before He can go on to tell all the meaning of what He has 'done unto us.' The ground of the petition is twofold. Verses 2 and 3 represent the glory sought for, as the completion of the Son's mission and task. Already He had been endowed with 'authority over all flesh,' for the purpose of bestowing eternal life; and that eternal life stands in the knowledge of God, which is the same as the knowledge of Christ. The present gift to the Son and its purpose are thus precisely parallel with the further gift desired, and that is the necessary carrying out of this. The authority and office of the incarnate Christ demand the glory of, and consequent further manifestation by, the glorified Christ. The life which He comes to give is a life which flows from the revelation that He makes of the Father, received, not as mere intellectual knowledge, but as loving acquaintance. The second ground for the petition is in verse 4, the actual perfect fulfilment by the Son of that mission. What untroubled consciousness of sinless obedience and transparent shining through His life of the Father's likeness and will He must have had, who could thus assert His complete realisation of that Father's revealing purpose, as the ground of His deserving and desiring participation in the divine glory! Surely such words are either the acme of self-righteousness or the self-revealing speech of the Son of God.
