What does the Bible say about spiritual hearing and seeing?

The Scriptures emphasize the importance of spiritual hearing and seeing through passages like Proverbs 20:12 and Romans 10:14-17. Spiritual hearing involves receiving the gospel with an open heart, recognizing that faith is a gift from God. In Romans 10, Paul articulates that for one to call upon the Lord, they must first believe, and for them to believe, they must hear the gospel preached. This highlights that true faith cannot arise from mere human effort but must be accompanied by the divine revelation of God’s truth in Christ.
