How does God open our hearts to understand His Word?

The act of God opening our hearts is a work of the Holy Spirit, which allows us to truly understand and believe in His Word. In Acts 16:14, we see that the Lord opened Lydia's heart to respond to the message of the gospel. This demonstrates that understanding Scripture is not purely an intellectual exercise but a spiritual awakening that God performs in us. God's sovereign grace enables us to recognize the beauty of Christ in the scriptures, moving us from mere knowledge of religion to a vibrant faith in Him. Therefore, we must humbly ask God to open our hearts, as understanding comes from Him alone.
