“There is nothing outside of a person that can defile him by going into him. Rather, it is what comes out of a person that defiles him.”
Not food, but thoughts, words, and acts that come from the heart are what soil a man’s soul and make him unfit for God’s presence.
What are sources of defilement that the mind can be influenced by? What thoughts and attitudes displease the Lord? How can I be purified today?
