Life

Excerpt from How the Lord of Life Gives Life by John Piper



But the clearest answer in Acts to the question why a person believes the gospel is that God opens the heart. Lydia is the best example. Why did she believe? Acts 16:14 says, “The Lord opened her heart to pay attention to what was said by Paul.” Notice four aspects of this conversion.


1) “. . . what was said by Paul.” First, someone must speak the gospel. God does not open the eyes of the heart to see nothing. He opens them to see the glory of Christ in the truth of the gospel (2 Corinthians 4:4-6). Therefore, we must speak the gospel. We don’t make the new birth happen when we do. But we fit into God’s way of doing it. The point of the new birth is to grant spiritual sight. The point of speaking the gospel is give something to see. New birth is for the glory of Christ. Therefore, God causes it to happen when Christ is lifted up.


2) “The Lord . . .” Second, the speaker of the gospel relies upon the Lord. Prayer is not mentioned here. But that is what we do when we realize that it is the Lord who is the decisive actor, not us. We have a significant role in speaking the gospel, but it is the Lord himself who does the decisive work.


3) “. . . opened her heart . . .” Since the key problem in not believing the gospel is the hardness or the closedness of the heart, this is where the Lord does his decisive work. He “opens the heart” of Lydia. This means he takes out the heart of stone, and puts in the heart of flesh (Ezekiel 36:26); he says with sovereign authority, “Let there be light,” and “shines in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ” (2 Corinthians 4:6). So the darkness flies away and the light of truth reveals the irresistible beauty of Christ in the gospel.


4) “. . . to pay attention to what was said by Paul.” The effect of the Lord’s opening her heart is a true spiritual hearing of the gospel. “Pay attention to” is a weak translation of the Greek prosechein. It is stronger than that in this content. In this verse, it is a hearing with attachment. The work of the Lord does not just help her focus. It brings about faith. She was “granted repentance” (2 Timothy 2:25) and faith (Philippians 1:29).


Or, in the terms of John 6, she was given by the Father to the Son (v. 37), and was drawn by the Father to the Son (v. 44), and was granted by the Father to come to the Son (v. 65). She was “made alive” (Ephesians 2:5) and born again (John 3:3, 7).
