When truth is being incorporated into earthly goodness,
it hurts to begin with. It weighs on our conscience and
worries us, since we have cravings that spiritual truth
fights against. But this initial pain slowly lessens and finally
disappears. It is like a sick and feeble body that can
be restored to health only by a painful cure; in that state,
it has pain at first.
