What does the Bible say about the heart and lips in teaching?

Proverbs 16:23 indicates that the heart of the wise influences the mouth, demonstrating that true teaching comes from a heart that knows the Lord. When our hearts are captured by the truths of Christ, our lips will then express that knowledge. This process highlights the necessity of heart transformation before effective communication of God's truths can occur. As reiterated in James 1:5, wisdom is a gift from God, urging us to seek it with a humble heart that recognizes its dependence on divine revelation.
