Have students step into a chair. Once in the chair place a blindfold on their eyes and be sure that they cannot see. (Some will try to look down through the blindfolds) Once they are blindfolded, silently place 3 chairs in front of them (sideways) Now ask them do they have faith in God? Once they say yes ask them to step out on faith. The first step will be hard but each step after that will get easier.
I used this in the Sunday School class to demonstrate that we should walk by faith and not by sight. I pray that this is useful for somebody.
