If ever you utter a sharp word say: O wretched man that I am!
And every time you lose your temper, kneel down and understand that it never was meant by God that this was to be the state in which His child should remain.
Would to God you could forget everything else, and cry out: O wretched man that I am! who shall deliver me from the body of this death?
Thanks be to God through Jesus Christ our Lord!
