A call to prayer

I've been reading the book of Joel this week (I've taken to reading a different book of the Bible every day for seven days in addition to my regular program of Bible reading. This gives me an opportunity to sink in to the view of the writer and the direction of the Spirit in his life). Anyway, I can't escape Joel 2:12-following:
12 Even now—

this is the Lord’s declaration—
turn to Me with all your heart,with fasting, weeping, and mourning.13 Tear your hearts,not just your clothes,and return to the Lord your God.
For He is gracious and compassionate,slow to anger, rich in faithful love,
and He relents from sending disaster.
14 Who knows? He may turn and relent and leave a blessing behind Him,
so you can offer grain and wine to the Lord your God.
15 Blow the horn in Zion!Announce a sacred fast;proclaim an assembly.
16 Gather the people;sanctify the congregation;
assemble the aged;gather the children,even those nursing at the breast.
Let the bridegroom leave his bedroom,and the bride her honeymoon chamber.
17 Let the priests, the Lord’s ministers,weep between the portico
and the altar.Let them say:
“Have pity on Your people, Lord,and do not make Your inheritance a disgrace,
an object of scorn among the nations. Why should it be said among the peoples,
‘Where is their God?’ ”
What if we as leaders among the people of God took one day every week - say, Thursday- and spent the day fasting and praying for God to move in our congregation, our local and regional and national denominational agencies and for Kingdom Expansion? What if we built in some sort of accountability, i.e. praying together...online prayer groups, praying together over the phone, etc....?
Just an idea...I'm open to other suggestions.
The bottom line- at least for me- am I desperate enough to see God move that I am willing to get out of His way?
