No man has understanding if he is not humble

No man has understanding if he is not humble, and he who lacks humility is devoid of understanding. No man is humble if he is not peaceful, and he who is not peaceful is not humble. And no man is peaceful without rejoicing. In all the paths upon which men journey in this world they will find no peace, until they draw nigh to hope in God. The heart finds no peace from toil and from stumbling-blocks, until hope enters it, makes it peaceful, and pours joy into it. That worshipful and all-holy mouth spoke of this when it said, “Come unto Me, all ye that labor and are heavy laden, and I will give you rest.” Draw nigh, He and fear.
St. Isaac of Syria
