When I was ill and I did not give up my anger towards my brother, I saw that the angels were withdrawing from me and were crying over the death of my soul and that the demons were rejoicing at my anger. That is why I asked you to go to the brother and implore him for his forgiveness for me. When you brought him to me, and I bowed before him and he turned away from me, I saw an angel who was holding a fiery spear and who struck the unforgiving one with it. Immediately, he fell dead. But to me the same angel gave his hand and helped me up, and here I am healthy again.”

How often in life it happens that embittered and irreconciled Christians suddenly leave this world and set out for the kingdom of eternity with anger in their souls! What pardon can they expect from God if they themselves have not forgiven those who have sinned against them?! It is terrible to live irreconciled, but it is even worse to die irreconciled! Bitterness and strife make the soul unfit to bear divine grace, and thus they destroy it.
