" Furthermore, if you are still in the cave of doubt and sin, plead with God to set you free. You cannot present a better prayer than the prayer of David in the cave: “Bring my soul out of prison, that I may praise thy name” (Ps. 142:7). If you are in prison, you cannot get out by yourself. You may grab the bars and try to shake them, but they are unmovable. You cannot break them with your hands. You may meditate, think, invent, and devise, but you cannot get through those bars. However, there is a hand that can cut bars of iron. Oh, prisoner in the iron cage, there is a hand that can open your cage and set you free! You do not have to be a prisoner. You do not have to be confined. You may walk in freedom through Jesus Christ, the Savior. Only trust Him, and believingly pray David’s prayer right now: “Bring my soul out of prison, that I may praise thy name” (v. 7). He will set you free! "
