I think this is mostly the right words.

I heard a man say that he didn’t think that prayer would do much good; that he didn’t think that God would care enough to answer us. But I am sure that if he prayed to God about these things, my God would hear and answer him cause prayer changes things.

Chorus:
Don’t you know that prayer changes things. It changes hearts, it’ll make them sing. Made the lame man walk, made the blind man see; it’ll give new life for you and me! It’ll lift you up when you’re down-hearted and you will hear the angels sing. Oh praise the Lord for your salvation, for ya know that prayer changes things.

When you’re in trouble and you need a friend and you don’t know what to do, just take your troubles to the Lord, I know He’s gonna see you through. He’ll lift you up from the sinking sand, sweet peace to you He’ll bring; and you will find that answered prayer cause prayer changes things.

Looking for an old church song lyrics to "Prayer Changes Things". CHORUS - Don't you know that prayer changes things. It'll bring new life, it'll make you sing. Makes the lame man walk, makes the blind man see. VERSE - If you're in trouble and you need a friend, but you don't know what to do. (Can't remember the 2 verses). This is not the Deitrick Haddon song.....
