Honor the Name of God!
This commandment commands to revere God by not using His name in vain. We must respect Him in all our ways and do not use His name in public or when we are alones with disrespect, falsehood and emptiness; in abusive and irreverent jargon. If we have established our relationship with Him, than we must learn to show proper respect to His name. Profanity is the common way how people desecrate and despise the name of living God. The name of God is despised also of all times religious leaders who, put it simple, has acted in the name of God just "to obtain wealth, power and dominion."
Paul in Romans 2:17-24 explains how God's name is blasphemed among the Gentiles by religion leaders.
The same is also today. If we have a humble, thankful, loving heart to God and His commandments - to love the God and each other - than we are fulfilled His requirements; and we will be careful not to disgrace and abuse the name of our loving Father. If we have a proud, vainglorious boasting in God and we profess His name outwardly, than we are just a hypocrites as that time Jewish leaders were, and some of our time religious leaders are; and the truth is not in us.
What can be more sad than that how our (and all times) religious leaders in so many ways do blaspheme and slander His Holy name! In regard to religious leaders Jesus said – "Woe to you, teachers of the law and Pharisees, you hypocrites! You are like whitewashed tombs, which look beautiful on the outside but on the inside are full of the bones of the dead and everything unclean. In the same way, on the outside you appear to people as righteous but on the inside you are full of hypocrisy and wickedness." (Matthew 23:27-28).
The name of God the Father and that of His Son must be revered, praised and glorified in every way. Jesus Christ is the only way how we can be saved and go to heaven. Christ means Saviour and Redeemer; the Annointed One. Jesus Christ is our Master and His name must be kept holy, His and our Father's name.
If we truly love the Lord our God with all our heart and with all our soul and with all our mind than we will be careful in our speach and will learn to revere and praise His name always. We will love Him will and will be careful to honor His name in every way.
"Praise the LORD. Praise the name of the LORD; praise Him, you servants of the LORD."
