"For confusion arises within us. It does not come from the nature of circumstances, but from the infirmity of our minds. If we were disturbed because of what befalls us, then all people would have to be troubled. For we all sail the same sea; it is impossible to escape the waves and the spray.
But if there are some who stand beyond the influence of the storm and the raging sea, then it is clear that it is not the outward circumstances which make the storm within us. Rather, it is the disposition or condition of our own minds.
Therefore, we should so order the mind that it may bear all things contentedly in Christ. Then we shall have no storm, nor even a ripple, within us, but always a clear and steady calm."
St. John Chrysostom
