2 Corinthians 1:20 (ESV)
For all the promises of God find their Yes in him. That is why it is through him that we utter our Amen to God for his glory.
The word "amen" is a most remarkable word. It was transliterated directly from the Hebrew into the Koine Greek of the New Testament, then into Latin and into English and many other languages, so that it is practically a universal word. It has been called the best-known word in human speech. The word is directly related--in fact, almost identical--to the Hebrew word for "believe" (aman), or "faithful." Thus, it came to mean "sure" or truly," an expression of absolute trust and confidence. When one believes God, he indicates his faith by an "amen." When God makes a promise, the believer's response is "amen"--"so it will be!" In the New Testament, it is often translated "verily" or "truly." When we pray according to His Word and His will, we know God will answer, so we close with an "amen," and so also do we conclude a great hymn or anthem of praise and faith.
The word is even a title of Christ Himself. The last of His letters to the seven churches begins with a remarkable salutation by the glorified Lord: "These things saith the Amen, the faithful and true witness, the beginning of the creation of God" (Revelation 3:14). We can be preeminently certain that His Word is always faithful and true, because He is none other than the Creator of all things, and thus He is our eternal "Amen." As our text reminds us, every promise of God in Christ is "yea and amen," as strong an affirmation of truth as can be expressed in the Greek language.
It is, therefore, profoundly meaningful that the entire Bible closes with an "amen." "The grace of our Lord Jesus Christ be with you all. Amen" (Revelation 22:21), assuring everyone who reads these words that the whole Book is absolutely true and trustworthy. Amen!
Dear Lord, we thank You that You are eternal. But even more then that that You are absolutely true and trustworthy. In the Name of Jesus, Amen.
