An oldie, but a goodie.
If you really think about the lyrics in the chorus, it is a bit of an interesting paradox. Essentially, it is asking for HELP from God to put FAITH in God. At first glance, that might seem strange, but in reality, building more faith in God is something that is really beyond our natural, human capabilities. In essence, we have to have faith that God will help us have more faith in Him. It is a beautiful cycle if you really let it sink in.
