The most effective moment you can do on the stage is to move from the past, you're right, and the audience is left to the future. By using the stage this way, you walk your audience from their past to the present finally to their future. It's very rare that you find a speaker who knows about it; when they do it, it's just so brilliant. We see time as human beings going from the pastor on our left to thefuture on our right. When we're watching a stage or looking at a screen, if you sit still and you visualize, you might see the past behind you in the future in front of you.
