For The Love Of GodSample

FROM TIME TO TIME IN THESE two volumes I have drawn attention to the fact that the way a biblical writer uses a word may not be the same way we use it. The serious reader of the Bible will then want to take special pains to avoid reading into the Bible what it does not say.

On the night he was betrayed, the Lord Jesus prayed for his followers in these terms: “Sanctify them by the truth; your word is truth. As you have sent me into the world, I have sent them into the world. For them I sanctify myself, that they too may be truly sanctified” (John 17:17-19). Observe:

First, this side of the Reformation “sanctification” usually refers to the gradual growth in grace that flows out of conversion. In justification God declares us to be just, on account of the sacrifice that his Son has offered up on our behalf; in sanctification, God continues to work in us to make us more and more holy, “sanctified,” maturing into conformity with Jesus Christ. There is nothing wrong with talking like that: in the domain of systematic theology, the categories are reasonably clear. And after all, whether or not the word “sanctification” is used, there are plenty of passages that depict this sort of growth in grace (e.g., Phil. 3:10ff.).

Second, that sort of use of “sanctification” makes little sense of John 17:19. When Jesus says that for the sake of his disciples “I sanctify myself,” he does not mean that for their sakes he becomes more holy than he was, a little more mature and consistent perhaps. Rather, in the light of John’s closing chapters, he means that he totally devotes himself to his Father’s will—and God’s will is that Jesus go to the cross. Jesus is entirely reserved for what the Father wants; he sanctifies himself.

Third, Jesus’ purpose in such obedience is that his disciples “may be truly sanctified” (John 17:19). Because of Jesus’ self-sanctification he goes to the cross and dies for his own; in consequence of this cross-work, his disciples are truly “sanctified,” i.e., set aside for God. This sounds like what systematicians call “positional sanctification”: the focus is not on growing conformity to God, but on the transformation of one’s position before God owing to Jesus’ decisive atonement.

Fourth, what Jesus asks for in his prayer is that his Father “sanctify” his disciples by the truth, i.e., by his word which is truth (John 17:17). He may simply be asking that they be decisively “sanctified” by the truth of the Gospel. But if an experiential, long-term dimension is also in view, this passage tells us how to become more “sanctified”—in line with Psalm 1:2; 119:109, 111.
