The end of our journey is the Kingdom of God. But we ought diligently to inquire what our aim is to be, for, if it be not known and recognized, we shall only tire ourselves out in vain, since when a man knows not the way he is going, his journey is mere toil and not progress.
The end of our profession is, as we have said, the Kingdom of God…our immediate journey…is purity of heart, without which it is not possible for anyone to arrive at the end….Whatever, then, can guide our steps to this, namely, purity of heart, we must follow with all our powers, and what would draw us away from it we must avoid as deadly and evil.
