John 17:13-19 English Standard Version

13 But now I am coming to you, and these things I speak in the world, that they may have my joy fulfilled in themselves. 14 I have given them your word, and the world has hated them because they are not of the world, just as I am not of the world. 15 I do not ask that you take them out of the world, but that you keep them from the evil one. 16 They are not of the world, just as I am not of the world. 17 Sanctify them in the truth; your word is truth. 18 As you sent me into the world, so I have sent them into the world. 19 And for their sake I consecrate myself, that they also may be sanctified in truth.

Our High Priest’s prayer continues and while I wish to move on to other prayers in the bible, the Spirit says “Not yet”.

Rather than going point by point with this section let us use the focal point of His prayer for us to study why He asked the Father to sanctify us.

Sanctification:

Etymology:

The root is found in the Old Testament in the Hebrew verb qadhash, in the New Testament in the Greek verb hagoazo. The noun “sanctification” (hagiasmos) does not occur in the Old Testament and is found but 10 times in the New Testament, but the roots noted above appear in a group of important words which are of very frequent occurrence. These words are “holy,” “hallow,” “hallowed,” “holiness,” “consecrate,” “saint,” “sanctify,” “sanctification.” It must be borne in mind that these words are all translations of the same root, and that therefore no one of them can be treated adequately without reference to the others. All have undergone a certain development. Broadly stated, this has been from the formal, or ritual, to the ethical, and these different meanings must be carefully distinguished. (end quote)

There is no simple answer to cover all the broader usages associated with sanctify. What I would say is this, in this prayer it is a thing done to us and for us rather than a response to what is expected of us.

A key element of this prayer of sanctification is in verse 17. “Sanctify them in the truth; your word is truth.” This is why we hold our Bible to be the Holy Bible. Take it to heart.
