“When you pray, don’t be like the hypocrites who love to pray publicly on street corners and in the synagogues where everyone can see them. I tell you the truth, that is all the reward they will ever get. But when you pray, go away by yourself, shut the door behind you, and pray to your Father in private. Then your Father, who sees everything, will reward you.”
–Matthew 6:5-6
If they pray, they should do so privately. They should not stand on the street corners and use prayer to tout themselves.
I don’t think that means we should’t ask people to pray. Yes, criticize for not meaning it, don’t criticize praying or the asking for prayer itself.
