John 17:19

sanctify Or, consecrate, as in John 17:17. Christ does for Himself that which He prays the Father to do for His disciples. In John 10:36 He speaks of Himself as consecrated by the Father; set apart for a sacred purpose. But only thus far is the consecration of Christ and of His disciples the same. In them it also implied redemption and cleansing from sin; and in this sense the word is frequently connected with -purify" (2 Corinthians 7:1; Ephesians 5:26; 2 Timothy 2:21; Hebrews 9:13). The radical meaning of the word is not separation, as is sometimes stated, but holiness, which involves separation, viz. the being set apart for God.

might be sanctified through the truth Rather, may be sanctifiedor consecrated in truth. - In truth" = in reality and not merely in name or appearance; the expression is quite distinct from -in thetruth" in John 17:17. As a Priest consecrated by the Father (John 10:36) He consecrates Himself as a Sacrifice (Ephesians 5:2), and thereby obtains a real internal consecration for them through the Paraclete (John 16:7).
