For that is the true honor of His name, to look to it and call upon it for all consolation (Psalm 66:2; 105:1). Then - as we have heard in the First Commandment - the heart of faith gives God the honor due Him first. Afterward, the lips give Him honor by confession.
This is also a useful habit and very effective against the devil. He is ever around us and lies in wait to bring us into sin and shame, disaster and trouble (2 Timothy 2:26). But he hates to hear God's name and cannot remain long where it is spoken and called upon from the heart.
