Once again St. Isaac's words stir the heart to hope and the desire for God. As a homily it offers with surprising brevity a clear and rich explication of the spiritual life. He begins by calling us to humbly follow the spiritual path common to all men. God's grace can work when and as it will in a person's life, but we should strive to walk the known paths that lead to virtue. The more one grows in virtue the more the soul's insatiable desire for virtue seizes hold. Discussion ensued about perhaps how uncommon an experience that is today. Do we experience a growing and insatiable desire for virtue within our souls?
Perfection is the standard for Christians in the spiritual life. Union with God means sharing in His virtues and embodying them in our lives. For example, the whole sum of the deeds of mercy immediately brings a soul into communion with the unity of the glory of the Godhead's splendor.
The truth of this is manifest in speech: That which comes from righteous activity is a treasury of hope, but wisdom not based on righteous activity is a deposit of disgrace. Words arising out of experience transform the listener.
Isaac concludes by reminding us that all good things come through God and are wrought in us in secret through baptism and faith. Any virtue we possess comes through these mediators and through them we have been called by our Lord Jesus Christ to His good labors.
