The question has been asked, “If God knows what we are going to pray before we pray it, then why pray?”
Here is one answer I see in
Revelation 5. When we progress from knowing that God knows what we are going to pray to actually uttering the prayer, we exit the arguments of a skeptic and enter the high revelation of the Authority who proves Himself true. Why pray? Most simply, to converse with the God of heaven and earth. When we pray we break camp and join the innumerable ranks of heaven; we lose our preferences and find what the Lamb loves; we forget all mortal esteem with matching vocabulary until heaven’s effluent speech becomes our tongue.
Pray. Cast your cares before the Lamb who redeemed you to God by His blood and has made you kings and priests to your God to reign in the earth. Pray. The prayers of the saints are golden bowls of incense held in the hands of heaven’s strange and living creatures and the twenty-four elders. Pray. Join the voices of many—of ten thousand times ten thousand, and thousands of thousands— and of every creature which is in heaven and on the earth and under the earth and in the sea, giving glory and honor and thanks to Him who sits on the throne, resounding “AMEN!”. Pray. Hold tenacious this eternal worship from before, around, and in the midst of the throne. Pray. It is a new song. It seems God’s purpose for prayer far exceeds ours.
