TThe problem is that this isn’t what you’re supposed to be doing in a prayer.You’re supposed to be talking to God.What’s more, if you’re leading a group of people in prayer then you’re supposed to be representing their thoughts to God.
At least for the moment, you’re acting as the group’s representative to God.And the group is meant to agree to what you are saying to God on their behalf. That’s why they are expected to say “Amen” or “Lord, hear our prayer” or whatever the local custom is as soon as you stop praying.This means that the group is giving you a sacred trust. They are letting you talk to God on their behalf.
You thus have a responsibility to represent the group in a way they approve of and not go off promoting your agenda rather than theirs.There is some give an take here. After all, you’re not a mind reader, and you don’t know what everybody in the group thinks. But you do have a responsibility, as the group’s representative, to represent its petitions.
Any time the representative of a group starts promoting his agenda over that of the group, it’s bound to cause resentment.
Particularly when you have a captive audience.
