The Work of the Holy Spirit
John 15:26–16:16
The Spirit of truth . . . will bear witness about me. John 15:26

When we say that the Holy Spirit speaks through the Bible to the individual heart, precisely what does the Holy Spirit do?

First, the Holy Spirit gives comprehension. Apart from the ministry of the Holy Spirit there is no understanding of spiritual things. The Bible is taught, but men and women do not comprehend it. The gospel is proclaimed forcefully, but the unregenerate consider it nonsense. What is wrong? What is wrong is that the Holy Spirit has not yet granted understanding. This is what Paul is speaking about in 1 Corinthians 2 when he says, “The natural person does not accept the things of the Spirit of God, for they are folly to him, and he is not able to understand them because they are spiritually discerned” (v. 14). Without the internal witness of the Holy Spirit, the unregenerate comprehend nothing of the gospel. On the other hand, where the Holy Spirit is at work, understanding follows. This is true regardless of the obstacles to comprehension.

The second thing the Holy Spirit brings is conviction. This is necessary too because it is not enough merely to have a comprehension of spiritual things. Comprehension is necessary. But if we have a proper comprehension, this will involve an understanding of our own sin and we will need to be convicted of our sin. Jesus says, speaking of the Spirit, “When he comes, he will convict the world concerning sin and righteousness and judgment: concerning sin, because they do not believe in me; concerning righteousness, because I go to the Father, and you will see me no longer; concerning judgment, because the ruler of this world is judged” (John 16:8–11). It is the Holy Spirit’s work to bring such conviction.

Third, the Holy Spirit will also bring commitment to the Lord Jesus Christ. Having comprehended the gospel and having been convicted of sin to the point of repentance, the one to whom the Holy Spirit bears his witness then commits himself to Christ as Lord and Savior.

Is he at work in your heart? Do you know that Jesus Christ is indeed the Son of God, as he claimed to be, and do you understand that he died in your place, the just for the unjust, that he might save you from sin? Are you convicted of sin so that you are sorry for sin and willing to turn from it? Have you reached the point of committing yourself to Jesus? If you have, say, “Lord Jesus Christ, I am a sinner but I believe that you are the Son of God and that you died for me. Accept me now as one of your children and help me to follow you faithfully until my life’s end.”
