As Isaac guides us through the final part of homily 68, he reminds us that the heart must long for converse with God. In this is found the greatest joy of unbroken stillness. He also reminds us that purity of heart is more valuable than all things and that without it all effort is profitless. If we fall into sin through heedlessness, however, we are not abandoned and can return to this unbroken stillness through unremitting vigils with reading and frequent prostrations. We must let the Fathers renew our fervor and we must humble ourselves in mind and body in order that God might lift us up again. When one has obtained this stillness there is little need for persuasive argument for one has come to experience the Truth.
In Homily 69 Isaac makes it very clear that hourly we experience variations within our soul and repentance is a constant need. Downfalls will occur which are opposed even to the will aim. We must not let our soul become despondent or dejected for this is the very course of growth – spiritual warfare as a movement between the struggle with sin in our weakness and the consolation of God‘s grace. He who thinks that he can ever rise above this spiritual warfare becomes even more vulnerable prey for the wolf. As long as we are in this world we are to enter into the fray and fight the good fight of faith. We must not linger in consolation as if it were an end in itself but must remain humble before God
