The Gravity of Prayer is a short message about the importance of prayer. The fictional character in the movie Gravity, Dr. Ryan Stone, played by Sandra Bullock revealed that she did not know how to pray. No one had ever taught her. Don't wait until you are facing death to begin praying. Prayer is the Christian's lifeline to communicating with a loving and forgiving God. Prayer is essential, it is rewarding, and it can save your life.
