Continuing with homily number 48, Saint Isaac speaks to us of the essential place of asceticism in the spiritual life. We must seek in every way to allow the passions to be transformed by the grace of God and through discipline of mind and body. Only in this way will we be able to experience something of the lasting joy and peace of God and the Kingdom. Through our senses we are in a constant state of communion with and receptivity to the world around us. Yet our sin makes us vulnerable and our vision of the things of the world become distorted. Conscience becomes malformed and so good appears to be evil and evil appears to be good. Only by being dead to life in this world, that is, dead to our attachment to the things of this world and our own desires can we be free to desire and love God. Ease and idleness are the very destruction of the soul and, St. Isaac tells us, injure the soul more than demons. Through our negligence we open the door for temptations to freely enter and so we darken the soul.
