“There is apparently a profound inability in humans to stick to a straight line when blind-folded, or when there is no fixed point–no sun, no moon, no mountain-top to guide them.” (1:55)
Wow. How profound this is. Think about how we are spiritually blind without Jesus the light of the world opening our eyes and guiding us.
“I am the light of the world. Whoever follows me will never walk in darkness, but will have the light of life.” (John 8:12)
