John Ortberg on Keeping Your Soul in Condition

 The soul, the only aspect of a human being the Bible says is eternal, is like a car, according to megachurch pastor and award-winning author John Ortberg. "If you want to care for your car, you kind of have to know what the parts do, what the carburetor does, what the fan belt does — somebody's gotta know that if they want to care for it."

And the car — that is, the soul — has nine needs that must be met in order to function at optimal efficiency, or in this case, to experience God's shalom, Ortberg suggests in his new book Soul Keeping: Caring for the Most Important Part of You.
