Your faith can only move mountains if God wants them moved. Faith isn't a blind feeling that God will do whatever we ask but it's putting our full trust and confidence in God regardless of what He chooses to do. This was shown by these men:

(Daniel 3:13-18 NIV) Furious with rage, Nebuchadnezzar summoned Shadrach, Meshach and Abednego. So these men were brought before the king, {14} and Nebuchadnezzar said to them, "Is it true, Shadrach, Meshach and Abednego, that you do not serve my gods or worship the image of gold I have set up? {15} Now when you hear the sound of the horn, flute, zither, lyre, harp, pipes and all kinds of music, if you are ready to fall down and worship the image I made, very good. But if you do not worship it, you will be thrown immediately into a blazing furnace. Then what god will be able to rescue you from my hand?" {16} Shadrach, Meshach and Abednego replied to the king, "O Nebuchadnezzar, we do not need to defend ourselves before you in this matter. {17} If we are thrown into the blazing furnace, the God we serve is able to save us from it, and he will rescue us from your hand, O king. {18} But even if he does not, we want you to know, O king, that we will not serve your gods or worship the image of gold you have set up."

God saved them so that not a hair on their heads was singed. Neither did their clothes smell like smoke.
