If you are patient, the Holy Spirit that dwells in you will be pure. He will not be darkened by any evil spirit, he will rejoice and be glad; and with the vessel in which he dwells, he will serve God in gladness, having great peace within himself. But if any outburst of anger takes place, the Holy Spirit seeks to depart because He does not have a pure place. For the Lord dwells in patience, but the devil in anger. The two spirits, then, when living in the same place, are in conflict with each other and are troublesome to the person in whom they dwell. For if an extremely small piece of wormwood is put into a jar of honey, isn’t the honey entirely destroyed? And doesn’t the extremely small piece of wormwood take away the sweetness of the honey entirely so that it no longer pleases its owner, but has become bitter and lost its use? But if the wormwood isn’t put into the honey, then the honey remains sweet and is useful to its owner. You see, then, that patience is sweeter than honey. It is useful to God, and the Lord dwells in it. But anger is bitter and useless. If anger is mixed with patience, then the patience is polluted, and its prayer becomes useless to God.
