One of the first prayers I learned was the Lord’s prayer. It is a template of how the disciples are supposed to pray. I’ve mouthed those words a thousand times without any extra thought or meaning about what I was really asking God to do in my life let alone the world. “Thy kingdom come" literally is a petition for God to reign. You are giving God permission to have his way in your life. You are giving God permission to set up residence in your life. You are asking God to make your world like heaven. Maybe that explains why there is so much turmoil. Light and darkness can’t exact in the same space. Peace and war are opposite extremes. Just remember the next time you pray these words what you are really praying. God let your kingdom come.
