Let's pray for revival!

A friend invited me to a group that is praying for revival in Australia. Timing is wrong, so I won't be able to attend.

But I'm not sure I want to attend.

Here's how the early church prayed:

And now, Lord, take note of their threats, and grant that Your bond-servants may speak Your word with all confidence (Acts 4:29)

And how Paul requested prayer:

With all prayer and petition pray at all times in the Spirit, and with this in view, be on the alert with all perseverance and petition for all the saints, ¹⁹ and pray on my behalf, that utterance may be given to me in the opening of my mouth, to make known with boldness the mystery of the gospel, ²⁰ for which I am an ambassador in chains; that in proclaiming it I may speak boldly, as I ought to speak (Ephesians 6:18ff) 

No one prayed for 'revival' then, but for  confidence, for boldness to proclaim the gospel.

Maybe that's what we need to pray!
