"We must begin to believe that God, in the mystery of prayer, has entrusted us with a force that can move the Heavenly world, and can bring its power down to earth." Andrew Murray
It is very apparent that God's ways are not our ways when it comes to intercessory prayer. Why would the God of the universe, limit himself to mere humans? But that is precisely what He does. Thankfully, it is not by human effort or power, but from the Holy Spirit God implanted in us when we first believed. God's Spirit in us moves His hand, but He requires that we cooperate with Him and pray. When we talk with God and bring the needs of others to Him in prayer, He moves! Call out to God, He is listening for your voice and waiting to answer you.
“This is what the LORD says, he who made the earth, the LORD who formed it and established it--the LORD is his name: “Call to me and I will answer you and tell you great and unsearchable things you do not know.” Jeremiah 33:2-3, NIV
