The word “amen” is a Hebrew word (אָמֵן) that is used 30 times in the Old Testament. It carries over into the Greek (ἀμήν) and is used 129 times in the New Testament.
“Amen” is a word that declares affirmation, agreement, and faith. According to Webster, the term “amen” means truly; certainly; used to express solemn ratification or hearty approval. Martin Luther echoes this in his explanation of the term “amen” at the end of the Lord’s Prayer: “This means that I should be certain that these petitions are pleasing to our Father in heaven, and are heard by Him; for He Himself has commanded us to pray in this way and has promised to hear us. Amen, amen means ‘yes, yes, it shall be so.’”
We often close our prayers with “amen” to express the sincerity of our agreement with the words prayed and our trust that God hears and answers it according His will. “Amen” is often used in worship, not only following prayers, but sometimes hymns as well. In some churches, “amen” is spoken freely and extemporaneously. Here at Faith Lutheran Church, as with many churches, “amen” is often part of the liturgy. It is the role of the congregation to say “amen” (rather than the pastor by himself), so for any part the service that has an “amen,” the congregation should rightly join in speaking it.
Jesus uses “amen” rather uniquely than the rest of Scripture in that He declares “amen” before making a statement rather than afterward. This perhaps emphasizes that His words and promises are sure and can be trusted, even before we know what they are, because we know they come from Him. One such example comes from His promise in John 5:24, “Amen, amen, I say to you, whoever hears My word and believes Him who sent Me has eternal life and does not come into judgment, but has passed from death into life.” Amen!
