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!
