Several verses in the Bible command Christians to pray. Matthew 6:5-8 instructs Christians to pray unhypocritically and without any ulterior motives. First Thessalonians 5:16-18 commands us to pray constantly and with thanksgiving in all situations. Jesus modeled for us the appropriate way to pray in Matthew 6:9-13. And Ephesians 6:17-18 equates prayer with a weapon of spiritual warfare. It is clear that we act in obedience to the Word of God when we pray. But why is it that we end all of our prayers with the word “amen?”
In order to answer this question, we need to look at the meaning of the word in its original languages. We must also analyze how the word itself is used throughout the Bible. Finally, we will look at practical applications for the use of “amen” in prayer. We say “amen,” but do we really know what it is that we are saying?
The Original Meaning of “Amen”
The word “amen” in English is a transliteration of the same word in the original languages of Hebrew and Greek. This essentially means that there was not an English equivalent of the word, so the same pronunciation of the original word was adopted into the English language as a new word. Some of the alternate definitions used to translate the same original Hebrew and Greek “amen” are “verily,” “truly,” and “let it be so.”

“Amen” Throughout the Bible
The Hebrew “amen” and the Greek “amen” occur a combined 182 times throughout the Old and New Testaments. In the English Standard Version of the Bible, the word “amen” occurs 56 times in 50 verses throughout the Old and New Testaments. This means that the translators of the ESV believed one of the alternate translations to be sufficient for 126 of the occurrences. But they saw a need to maintain “amen” in the other 56 verses.
Perhaps surprisingly, 14 out of the 22 verses using the word “amen” in the Old Testament are used as an affirmation of a curse. One example of this is in Deuteronomy 27:26: “‘Cursed be anyone who does not confirm the words of this law by doing them.’ And all the people shall say, ‘Amen.’” Israel was affirming the righteous law that God had sent, and in effect, they declared, “Let it be as you have said.”
In the New Testament, there is a radical shift in the usage of the word. Instead of being used a majority of the time for cursing, it becomes a word that overwhelmingly affirms the glory of God. It is used to call blessing and glory and honor on God and to call His presence with His people. It is a word that calls on the character and faithfulness of God Himself.
Second Corinthians provides a good explanation as to why this shift happened: “For the Son of God, Jesus Christ, whom we proclaimed among you, Silvanus and Timothy and I, was not Yes and No, but in Him it is always Yes. 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” (1:19-20).
It is also significant that the last word of the Bible is “Amen.” Revelation 22:20-21 says, “He who testifies to these things says, ‘Surely I am coming soon.’ Amen. Come, Lord Jesus! The grace of the Lord Jesus be with all. Amen.” By ending his testimony and ultimately the Word of God with the word “amen,” John is testifying about the veracity of God’s Word. He is coming into agreement with what God has said. And he is essentially calling upon God to fulfill His promises as He has revealed them to be.
