Because nobody else is dwelling on the mountain with you–if they are, you don’t usually rub shoulders–that’s why!  Valley living is relational, everyday, commonplace activities–challenging to our faith and our faithfulness.  Oswald Chambers–

We see His glory on the mountain, but we never live for His glory there. . . Most of us can do things if we are always at some heroic level of intensity, simply because of the natural selfishness of our own hearts.  But God wants us to be at the drab everyday level, where we live in the valley according to our personal relationship with Him.

Live out your mountaintop experience in the valley of the mundane.
