This is one of those truths that we all sort of struggle with. Can we really move mountains with prayer? The truth is YES. Sadly, this has been twisted and contorted by men and women not worthy to hold the name "pastor" into something we (and sometimes they!) call the prosperity gospel. The point of Jesus encouraging us to move mountains through prayer is not so that we would stamp our feet and demand he do things for us like a vending machine, but rather that we would trust and see that we serve a sovereign God who is king over all of human history. He has ordained it in such a way that his sovereign will is accomplished through our prayers. In this particular design we pay tribute to the words of Jesus in Matthew 17:20. You will notice the "serial" number on the trailer which references this verse (40 is the book number of Matthew).
So brother, sister go and pray. Pray that the mountains of death and sin that blind the world to Christ's worth would be moved.
