A Hebrew word meaning truly, surely, so be it, derived from the verb aman (to confirm, support, be faithful). The most universally retained word in Bible translation across all major languages. Used at the end of prayers as agreement, at the end of praises as confirmation, and twice consecutively (verily, verily in KJV) by Christ to introduce solemn declarations. Most strikingly, Christ Himself is called the Amen, the faithful and true witness in Revelation 3:14.
AMEN, n.
A scriptural Hebrew word; truly, surely, so be it; also a divine title applied to Christ.
Deuteronomy 27:15 — "And all the people shall answer and say, Amen."
Psalm 106:48 — "Blessed be the Lord God of Israel from everlasting to everlasting: and let all the people say, Amen."
John 3:3 — "Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God."
Revelation 3:14 — "These things saith the Amen, the faithful and true witness, the beginning of the creation of God."
Modern Christianity says amen as filler; Christ is the Amen and stands behind every promise.
Christ Himself is called the Amen in Revelation 3:14. The title is glorious: He is the personification of God's faithfulness, the one who stands behind every promise. For all the promises of God in him are yea, and in him Amen, unto the glory of God by us (2 Cor 1:20). Every Old Testament promise reaches its amen in Christ.
Modern Christianity often uses amen as conversational filler at the end of prayers, much as people use OK elsewhere. The word deserves more weight. When you say it, you are agreeing to the prayer's content, calling on God's faithfulness, and aligning yourself with the Amen Himself. Mean it. Christ stands behind every prayer prayed in His name.
