It's hard to be excited about a dead thing.
Consider that old pair of shoes tucked away in your closet, with the worn soles and strings literally hanging by a thread, now fit only for mowing and painting. Or your old cell phone--you know, the one with the cracked screen that slowed down to Windows 95 speeds before you replaced it. How often do you desire to go back to those dead devices?
This concept applies to literature as well. Sure, outdated events (history) can be interesting--and even thrilling. Aged books have a certain look, feel, and smell that add to their charm. But outdated instruction? Lifeless commands? Old riddles? We're more likely to yawn and nod off than to be energized and motivated.
Gratefully, our Bible isn't a dead thing.
