Enthusiasm is more active than faith, though enthusiasm cannot remove mountains nor call into action any of the omnipotent forces which faith can command. Activity is often at the expense of more solid, useful elements, and generally to the total neglect of prayer. To be too busy with God's work to commune with God, to be busy with doing church work without taking time to talk to God about His work, is the highway to backsliding, and many people have walked therein to the hurt of their immortal souls.
