Mark 11:23

"I tell you the truth, you can say to his mountain, "Go fall in to the sea: and if you have no doubt in your mind and believe that what you say will happen, God will do it for you"

As long as we have faith, that we trust in Our Father, and we have the courage and trust in ourselves, there is no peak we can't overcome. There is no mountain too big for our God and therefore there is no mountain too big for us. Maybe it is only God who can move mountains, but faith and prayer can move God.
