The power of prayer

“Lord, how are they increased that trouble me! many are they that rise up against me. Many there be which say of my soul, There is no help for him in God. Selah. But thou, O Lord, art a shield for me; my glory, and the lifter up of mine head. I cried unto the Lord with my voice, and he heard me out of his holy hill. Selah.” ‭‭Psalms‬ ‭3:1-4‬ ‭KJV‬‬
