As you are walking and looking down, you see the cracks in the sidewalk – along with the
dirt, the gum, the cigarette butts, etc.. There is no sense of direction and there is no focus.
When looking down, not only do you not see what is ahead of you but
you do not see what is coming down from above.
As Christians or brothers and sisters in Christ, when we are on that sidewalk,
how often do we walk looking down? How
often do we not look up to see what God is sending from above.
(inspired by a quote from C S Lewis)
