God is the Bigger Elvis is a poignant look at what it means to be totally swept up in relationship with God. Not only is it a great human-interest story, it is a powerful explication of the concept of vocation - and can certainly serve as a way to catechize about what it means to hear - and have the courage to obey, in spite of the temptation of other attractive options - God's voice in the circumstances of life.
Watch it. You will be moved. Share it and use it. The film is a gift to all.
