Faith is the middle land between fear and a clear view of the future.
God did not give us the spirit of fear. Fear is the opposite of faith. Faith is stepping forward into the unknown believing that God is there to guide you. (and trusting Him to be not only a good guide, the the guide with your ultimate salvation and eternal life in mind)
Even most of the prophets, those who have seen the whole future of the world, did not have all the details of their lives spelled out to them. That would make faith unnecessary, and good luck to all prophesying without faith.
