“…if we don’t want to lose out in vain, worldly gains, how much more must we be careful not to harm ourselves spiritually! Worldly people seek material gain and don’t let it go to waste; is it right for spiritual people to throw away spiritual gain? But even if worldly people spend the money they have, they are at least wasting only material things, while we, when we do not accept an injustice, waste spiritual and heavenly things. We consume everything down here. Why trade the heavenly for the earthly?”
