"Wait on the Lord: be of good courage, and he shall strengthen thine heart: wait, I say, on the Lord" (Psalm 27:14)
There is an inactivity that, paradoxically, is the highest possible activity. There can be a suspension of the activity of the body, as when our Lord told His disciples to "tarry ye in the city of Jerusalem, until ye be endued with power from on high" (Luke 24:49). They waited. And the Holy Spirit came on them in power.
In the Old Testament, to wait on God meant coming before His presence with expectation and waiting there with physical and mental inactivity.
"Cease thy thinking, troubled Christian", one of the old poets wrote. There is a place where the mind quits trying to figure out its own way and throws itself wide open to God. And the shining glory of God comes down into the waiting life and imparts an activity.
Do you understand what I mean when I say that we can go to God with an activity that is inactive? We go to God with a heart that is not acting in the flesh or in the natural - trying to do something. We go to God in an attitude of waiting.
Hearing, I am receptive; seeing, I am active. Yet our bliss does not consist in being active but in begin receptive to God.
