Answer from ChatGPT:

In the Lord’s recovery, “Amen” is used very frequently because it is understood not merely as a way of ending a prayer, but as a way of actively responding to the Lord and agreeing with what is being spoken.

The practice has several layers:

1. Biblical meaning: “Amen” basically means “truly,” “surely,” or “so be it.” It is a Hebrew word carried directly into the New Testament. When someone says “Amen,” they are affirming, “Yes, this is true,” or “May this be so.”

2. A corporate response: Recovery meetings emphasize that the church is not primarily an audience listening to one person minister. Everyone is encouraged to function. Saying “Amen” is a very simple way for everyone to participate.

3. Affirming the Lord rather than merely the speaker: Ideally, when someone shares something concerning Christ or the Word, the “Amen” is directed toward what is true of the Lord—not simply, “I agree with that brother.”

4. Praying with the speaker: If someone prays, “Lord, we love You and want to enjoy You more,” others may say “Amen” because they are making that prayer their own.

5. Receiving the Word: Someone might read a verse and then make a short declaration about it. Others say “Amen” as an expression of receiving and agreeing with the truth.

6. Spiritual exercise: The Recovery places considerable emphasis on believers exercising their spirit in the meetings rather than remaining passive. Vocal responses—“Amen,” “Praise the Lord,” “Hallelujah,” etc.—are part of that practice.

There is actually a particularly relevant verse:

“For all the promises of God in Him are Yes; therefore also through Him is the Amen to God, unto the glory of God through us.” — 2 Corinthians 1:20, RcV

The Recovery’s understanding of that verse is that Christ Himself is God’s “Yes” to us, and our “Amen” is our response to God through Christ.

Why it can sound like a lot of Amens:

There’s also a cultural/meeting-practice component. In a typical Recovery meeting, people have been trained to respond audibly and frequently. So you might hear:

“The Lord Jesus is so wonderful!”
“Amen!”
“We just want to love Him!”
“Amen!”
“We need to exercise our spirit!”
“Amen!”

And sometimes it can become almost automatic.

That’s worth distinguishing from the biblical principle itself. The New Testament certainly supports corporate verbal affirmation—Paul explicitly says that the other believers should be able to say Amen to someone’s prayer (1 Corinthians 14:16). But the Bible doesn’t prescribe a particular frequency or meeting style for saying it.

So there are really two things going on:

1. Biblical principle: Amen = “Yes, I agree; may it be so,” and it can be a genuine corporate response to the Lord.

2. Recovery culture: frequent audible “Amens” have become one of the characteristic ways that Recovery meetings express corporate participation.

And, frankly, the second can sometimes continue even when the first isn’t happening very consciously. A person can say “Amen” because everyone else just said “Amen.” That doesn’t necessarily mean the practice itself is wrong; it means the spiritual reality behind the practice matters.
