After having spoken to us in great detail about the ineffable consolation of faith and the experience of God‘s love in prayer, Isaac begins to teach us how we must be conformed to the mind and heart of Christ. In particular he emphasizes the absolute need for mercy. Be merciful as your heavenly father is merciful comes to light vividly in this passage. Through mercy we become the physician of our own souls. Giving this mercy to others brings us great healing. We are never to be those who seek vengeance but rather those who only desire the conversion and repentance of others so that they might come to experience the healing mercy of God. We are to be the conduits of this mercy in the world.
We closed with a challenging paragraph. Isaac warns us not to think that God fails to see our motives. We cannot be crafty or knavish in our actions or take the love and the mercy of God for granted or hold he cheap. Death comes to us quickly and unexpectedly and so we must live every moment seeking to love God and to love one another.
