What does the Bible say about the significance of the word 'Amen'?

The word 'Amen' is one of the most universally recognized words across languages, fundamentally deriving from the Hebrew root for belief. Its use in Scripture emphasizes a declaration of faith and trust in God's promises. In Psalm 72, the repetition of 'Amen' underlines the church's agreement with God's truth and glory. Just as the Queen of Sheba affirmed Solomon's wisdom and majesty, the people of God, throughout generations, express agreement with God's majestic truths by affirming, 'Amen and amen.' This expression connects the believers' hearts to the faithful promises of God.
