19 And for them I make myself holy, so that they may be made truly holy.
20 My prayer is not for them only, but for all who will have faith in me through their word; 21 May they all be one! Even as you, Father, are in me and I am in you, so let them be in us, so that all men may come to have faith that you sent me. 22 And the glory which you have given to me I have given to them, so that they may be one even as we are one; 23 I in them, and you in me, so that they may be made completely one, and so that it may become clear to all men that you have sent me and that they are loved by you as I am loved by you.
Matthew Henry's Commentary on John 17:19-23
Commentary on John 17:17-19
(Read John 17:17-19)
Christ next prayed for the disciples, that they might not only be kept from evil, but made good. It is the prayer of Jesus for all that are his, that they may be made holy. Even disciples must pray for sanctifying grace. The means of giving this grace is, "through thy truth, thy word is truth." Sanctify them, set them apart for thyself and thy service. Own them in the office; let thy hand go with them. Jesus entirely devoted himself to his undertaking, and all the parts of it, especially the offering up himself without spot unto God, by the eternal Spirit. The real holiness of all true Christians is the fruit of Christ's death, by which the gift of the Holy Ghost was purchased; he gave himself for his church, to sanctify it. If our views have not this effect on us, they are not Divine truth, or we do not receive them by a living and a working faith, but as mere notions.
Commentary on John 17:20-23
(Read John 17:20-23)
Our Lord especially prayed, that all believers might be as one body under one head, animated by one soul, by their union with Christ and the Father in him, through the Holy Spirit dwelling in them. The more they dispute about lesser things, the more they throw doubts upon Christianity. Let us endeavour to keep the unity of the Spirit in the bond of peace, praying that all believers may be more and more united in one mind and one judgment. Thus shall we convince the world of the truth and excellence of our religion, and find more sweet communion with God and his saints.
