[Contentment] is the quiet of the heart All is sedate and still there…. [Contentment is not opposed to] a due sense of affliction. God gives his people leave to be sensible of what they suffer. Christ does not say, ‘Do not count as a cross what is a cross’: he says, ‘Take up your cross daily’. It is like physical health: if you take medicine and cannot hold it, but immediately vomit it up, or if you feel nothing and it does not move you—in either case the medicine does no good, but suggests that you are greatly disordered and will hardly be cured. So it is with the spirits of men under afflictions: if they cannot bear God’s potions and bring them up again, or if they are insensitive to them and no more affected by them than the body is by a drought of small beer, it is a sad symptom that their souls are in a dangerous and almost incurable condition. So this inward quietness is not in opposition to a sense of afflictions, for, indeed, there would be no true contentment if you were not apprehensive and sensible of your afflictions, when God is angry.
