The Lord revealed His wisdom by the way in which He healed man, becoming man without the slightest change or mutation. He demonstrated the equity of justice when in His self-abasement He submitted deliberately to the sentence to which what is passible in human nature is subject, and made that sentence a weapon for the destruction of sin and of the death which comes through sin — that is, for the destruction of pleasure and of the pain which pleasure engenders.
It was in this pleasure-pain syndrome that the dominion of sin and death lay; the tyranny of sin committed in pursuit of pleasure and the lordship of the painful death consequent upon sin….
…for in our desire to escape pain we seek refuge in pleasure, and so try to bring relief to our nature, hard pressed as it is by the torment of pain. But through tying in this way to blunt pain with pleasure, we but increase our sum of debts, for we cannot enjoy pleasure that does not lead to pain and suffering.
~St Maximos the Confessor
