A woman named Lydia, from the city of Thyatira, a seller of purple fabrics, a worshiper of God, was listening; and the Lord opened her heart to respond to the things spoken by Paul. (Acts 16:14, NASB)The manner of Lydia's conversion is a fine illustration of how God always redeems lost souls. From our human perspective, we may think we are seeking Him, that trusting Christ is merely a "decision" that lies within the power of our own will to choose, or that we are sovereign over our own hearts and affections. In reality, wherever you see a soul like Lydia's truly seeking God, you can be certain God is drawing her. Whenever someone trusts Christ, it is God who opens the heart to believe. If God Himself did not draw us to Christ, we would never come at all. Jesus was quite clear about this: "No man can come to Me unless the Father who sent Me draws him" (John 6:44). "No one can come to Me unless it has been granted to him by My Father" (John 6:45).
The fallen human heart is in absolute bondage to sin. Every sinner is just as helpless as Mary Magdalene was under the possession of those seven demons. Romans 8:7–8 says, "The carnal mind is enmity against God; for it is not subject to the law of God, nor indeed can be. So then, those who are in the flesh cannot please God." We are powerless to change our own hearts or turn from evil in order to do good: "Can the Ethiopian change his skin or the leopard its spots? Then may you also do good who are accustomed to do evil?" (Jer. 13:23). The love of evil is part of our fallen nature, and it is the very thing that makes it impossible for us to choose good over evil. Our wills are bent in accordance with what we love. We are in bondage to our own corruption. Scripture portrays the condition of every fallen sinner as a state of hopeless enslavement to sin.
Actually, it's even worse than that. it is a kind of death—an utter spiritual barrenness that leaves us totally at the mercy of the sinful lusts of our own flesh (Eph. 2:1–3). We are helpless to change our own hearts for the better....
[Lydia's] heart was truly open. She was a genuine seeker of God. But notice Luke's whole point: it was not that Lydia opened her own heart and ears to the truth. Yes, she was seeking, but even that was because God was drawing her. She was listening, but it was God who gave her ears to hear. She had an open heart, but it was God who opened her heart. Luke expressly affirms the sovereignty of God in Lydia's salvation....
If it were not for God's sovereign work drawing and opening the hearts of sinners to believe, no one would ever be saved. This is the very thing Paul has in mind in Ephesians 2, after stressing the utter spiritual deadness of sinners, when he says salvation—all of it—is a gift of God (Eph. 2:8–9).
Did you realize that even faith is God's gift to the believer? We don't reach down into our own hearts and summon faith from within by sheer willpower. God is the one who opens our hearts to believe. Repentance is something He graciously bestows (Acts 11:18; 2 Tim. 2:25).
I think all Christians have some intuitive understanding of this truth....We know in our hearts that our salvation is wholly and completely the work of God's grace, and not in any sense our own doing. All believers, like Lydia, must confess that it was God who first opened our hearts to believe.
...Grace doesn't push sinners against their wills toward Christ; it draws them willingly to Him—by first opening their hearts. It enables them to see their sin for what it is and empowers them to despise what they formerly loved. It also equips them to see Christ for who He truly is. Someone whose heart has been opened like that will inevitably find Christ Himself irresistible. That is precisely the meaning of the expression "irresistible grace." That is how God draws sinners to Himself. Luke's description of Lydia's conversion captures it beautifully. The Lord simply opened her heart to believe—and she did.
