Desperate Situation, please pray

Between Thursday night and Sunday night my calendar shows 7 speaking engagements to open the Word of God to people.
Unless God comes by His Spirit, that is 7 exhalings of hot air. If He comes and blesses, lives will be changed, the lost reached, hearts will be healed, relationships will grow, repentance will be rampant, zeal for His glory will be increased. And, mysteriously, your prayers (and mine) have a place in which happens. This Piper quote works for every Lord's Day when i speak, but 7 times makes me especially aware of the glorious possibilities. Please pray:

“Now we can say and again, safely and stunningly, what the awesome
place of prayer is in the purpose of God to fill the earth with his glory.
Not only has God made the accomplishment of his purposes hang on the
preaching of the word; he has also made the success of that preaching
hang on prayer. God’s goal to be glorified will not succeed without the
powerful proclamation of the gospel. And that gospel will not be
proclaimed in power to all the nations without the prevailing, earnest,
faith-filled prayers of God’s people. This is the awesome place of prayer
in the purpose of God for the world. That purpose won’t happen
without prayer.” John Piper, Let the Nations Be Glad!, p. 66.
