When we had the control of our lives over to the direction of the Holy Spirit, we will be led in our prayers, even as Christ Himself was lead. Intercession made according to the will of God will be met by definite and positive answers. It is not through our power we have authority with God, it is through our dependence of the Spirit of God that dwells within us. While it may not seem that prayer changes things, it will work at changing us. Romans 8:18-27 is a tremendous passage to read when we are overwhelmed by our circumstances and need to gain a fresh perspective on life.
