Let's make this perfectly clear from day one - this is not about praying for rain! It is about our sole reliance on our Lord!
The Lord has revealed His plans to use us for the unfolding of His kingdom in these last days. We have witnessed the working of His mighty hand. We have received awesome revelation of His purposes. Yes, Lord - Your kingdom come and Your will be done, BUT YET we are ravaged by drought, barrenness, tornadoes and floods. Perversion and death seem to have the upper hand.
At that moment - I believe we will witness the Lord reign and the Lord's rain!
