Be still and know that I am God; I will be exalted among the nations. Psalm 46:10 (NIV)
Medicine can easily consume all our waking hours, and probably nowhere more so than during housejobs. The new responsibility, the volume of work, perhaps not being able to get away from hospital during off duty hours because the residency is in the hospital -- all these things contribute to make it difficult to take time off, mentally and physically.
Life becomes busy, full and tiring. It's a very stark contrast to be asked to 'be still'. For one thing, it can be surprisingly difficult to be still after being busy. I'm often reminded of Elijah in this context, in his severe depression after being God's champion on Mount Carmel.
He needed spiritual and physical refreshment, both of which God provided. But God really touched the heart of Elijah's need, not in the obvious power and noise of earthquake or fire, but in a still, small voice -- just, I think, what he did not expect after God's mighty demonstration of power on Carmel.
It's hard to be still amid a busy schedule, and we shall always have the temptation of other things to occupy us. God wants to and does speak to us when we are still -- give him time to; he alone, by allowing us to experience and know him, can give our lives the perspective they need.
Father, don't let me so swamped with a busy schedule
that emptiness and depression characterise my inner life.
Refresh me and assure me of your strength,
as you let me know you in stillness.
Let me hear your still, small voice daily.
