I sanctify myself (egō hagiazō emauton). To his holy ministry to which the Father “sanctified” (hēgiasen) him (Joh 10:36).
That they themselves also may be sanctified in truth (hina ōsin kai autoi hēgiasmenoi en alētheiāi). Purpose clause with hina and the periphrastic perfect passive subjunctive of hagiazō (that they may remain sanctified). The act of Christ helps us, but by no means takes the place of personal consecration on the part of the believer. This high and holy prayer and act of Christ should shame any one who uses the livery of heaven to serve the devil in as does, alas, sometimes happen (2Co 11:13-15).
