What does the Bible say about the conversion of sinners?

In Acts 2, we see the powerful conversion of 3,000 individuals as a result of Peter's preaching, filled with the Holy Spirit. This miraculous transformation demonstrates God's sovereign work in drawing sinners to Himself. The apostle Peter emphasized that sinners cannot turn to God by their own volition, highlighting the necessity of divine intervention in the process of conversion. It reflects the doctrine of regeneration, illustrating that the new birth is essential for a genuine response to the Gospel.
