Tonight we read Saint Isaac’s homily 41. It is a rich explication of the workings of the human mind and heart. St. Isaac shows us how it is that we are drawn into sin. He makes it clear that our natural appetites and desires are not the source of sin but rather our tendency toward excess and the weakness of our will. When the appetites are well ordered there is peace within the human person. But when we give ourselves over to negligence, conceit or slothfulness the passions are enlivened and then we are drawn into sinful behavior. St. Isaac directs us in the last part of the homily to the experience of tribulation and affliction. The wisdom of the fathers is that affliction awakens us to our poverty and our need for God’s grace and healing. God will allow us to experience affliction in order to humble us and draw us back to himself. It is through such affliction that repentance is often born.
