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.

be sanctified—consecrated. The only difference between the application of the same term to Christ and the disciples is, as applied to Christ, that it means only to "consecrate"; whereas, in application to the disciples, it means to consecrate with the additional idea of previous sanctification, since nothing but what is holy can be presented as an offering. The whole self-sacrificing work of the disciples appears here as a mere result of the offering of Christ [Olshausen].

the truth—Though the article is wanting in the original here, we are not to translate, as in the Margin, "truly sanctified"; for the reference seems plainly to be "the truth" mentioned in Joh 17:17. (See on [1883]Joh 17:17).
