The expression was introduced by Martin Luther as Ordnung muss sein unter den Leuten ("Law must be among people"), Ordnung in the sense of True Law of God as opposed to human rules, for Orden und Regeln sind nichts ("Orders and rules are nothing") (on the same page) and Liebe zu Geld... ist nicht Gottes Werk oder Ordnung (Love for money... is not God's work or “Ordnung”).
Martin Luther's concept of "Law must be among people" emphasizes the importance of True Law of God over human-made laws. He believed that true order comes from God, not from rules and regulations.
