Prayer is powerful.  Here are 20 Bible truths that explain what prayer can do for you.

The power of prayer is the power of God. Our prayers move the heart and hand of God.

Since God is all-powerful, there is no limit as to what prayer can do.

Jeremiah 32:17  “Ah Lord God! behold, thou hast made the heaven and the earth by thy great power and stretched out arm, and there is nothing too hard for thee:”

Jeremiah 33:3  “Call unto me, and I will answer thee, and shew thee great and mighty things, which thou knowest not.”

God is able to answer our prayers beyond our imagination!  His power exceeds our capacity to ask or think.

Ephesians 3:20  “Now unto him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us,”

Christians are feeble in their own strength but become mighty when they pray.

William Cowper said, “Satan trembles when he sees the weakest saint upon their knees.”  No wonder our enemy works so hard to keep us from praying!
