For with God Nothing shall be impossible. Luke 1:37; Matthew 19:26
All intercession begins with the heart...the heart of God, the heart of the one praying and the heart of the ones being prayed for. Our heart must be in right standing with our Father God in order for our prayers to be effective. We can have roots that we are unaware of and those roots will hinder our prayers. God is looking for a willing and obedient heart...not a perfect vessel.
I don't know as much as I would like to about intercession. I am still learning. My prayer is that by sharing what I DO know and have experienced, it will encourage others to accept the call.
Prayer causes situations, circumstances and people's hearts to change, bringing God's will to fulfillment in the earth, and in our lives.
