John 17:13-19 And now come I to thee; and these things I speak in the world, that they might have my joy fulfilled in themselves. I have given them thy word; and the world hath hated them, because they are not of the world, even as I am not of the world. I pray not that thou should take them out of the world, but that thou should keep them from the evil. They are not of the world, even as I am not of the world. Sanctify them through thy truth: thy word is truth. As thou hast sent me into the world, even so have I also sent them into the world. And for their sakes I sanctify myself, that they also might be sanctified through the truth.
‘Out of the world’ – He does not pray for them to die and leave the world, nor seclude themselves in deserts or separate themselves from the world in communities and monasteries to escape temptation, but to live as lights and examples of God in the world (Matt. 5:16; Php. 2:15; Tit. 2:11-14; 1Cor. 5:10) and not to love the things of the world or socialize with worldly people (1 Cor. 5:9-13; 1 Pet. 4:3-4; 1 Jn. 2:15-17; 2 Jn. 1:9-11).
‘Sanctify’ the Greek word hagiazo which means to separate from a profane to a sacred use; to consecrate yourself wholly to God and His service. The primary meaning is separation, not making holy. It means to make holy only when the person or thing sanctified needs to be cleansed from sin or defilement in order to be fit to be separated unto God and His service. Material things such as a day (Gen. 2:3); the tabernacle (Ex. 29:43-44); clothes (Lev. 8:30); houses (Lev. 27:9-29); or the temple (2Chron. 7:16-20) must be cleansed from all defilement in order to be fit to be presented to God for His holy uses. God’s name (Ezek. 36:23); God (1Pet. 3:15); Christ (John 10:36; 17:19); or the already cleansed disciples (John 13:10; 15:3; 17:2, 6, 14, 16) need not be cleansed from sin.
‘As thou has sent me into the world, even so have I also sent them into the world’ – this being sent as God had sent Him applies to all disciples, for Christ is not praying “for these alone, but for them also which belief on Christ through their word” (Matt. 28:20; Mark 16:15-20; John 14:12; 20:21). This ‘sent into the world’ is to do whatever one chooses as their calling in life and then to daily implement the whole armour of God (Eph. 6:10-18) and your feet shod with the preparation of the gospel of peace, so that wherever we go on a day-to-day basis our ‘walking’ will demonstrate a life in Christ (1 Pet. 2:21-23) so that others will be drawn unto Him.
‘I sanctify myself, that they also might be sanctified through the truth.’ Jesus separated Himself unto God to do His will, even unto death, so that all disciples may benefit through His salvation for them and be sanctified continually as they get to know the Word (1Jn. 1:7; Eph. 5:26).
