How does God open blind eyes to the truth of the gospel?

In the sermon, it is emphasized that the inability to see spiritual truths is a result of our natural blindness to the gospel, which can only be remedied by the sovereign grace of God. He uses the preaching of the gospel as the instrument to reach the hearts of the unconverted. John 6:44 describes that no one can come to Christ unless the Father draws him. This underscores the necessity of divine intervention, enabling the sinner to understand and embrace the gospel message, leading to true faith and repentance. It is by God's power alone that dead hearts are made alive to receive salvation.
