Sometimes a phone starts ringing and people look around wondering whose phone that is before realizing it's theirs. Or there are places a cell phone just won't work. This picture of cell phones reminds us of how sometimes God is calling out to us through his word but it takes us a while to notice. Or sometimes we stay away from God's Word as if we were in a "dead spot." But unlike a cell phone, when it comes to God's Word it's not an inconvenience to "miss the call," it's a matter of life and death.
