You shall not take the name of the Lord your God in vain
(Arthur Pink, "The Ten Commandments")
"You shall not take the name of the Lord your God in vain: for the Lord will not hold him guiltless, who takes His name in vain." Exodus 20:7
This commandment bids us to speak of God with that frame of spirit which is agreeable to His dignity and solemnity and the majesty: that is, with the utmost sincerity, humility and reverence. O what high thoughts ought we to entertain of such a Being! In what holy awe should we stand of Him!
Anything pertaining to God should be spoken of with the greatest sobriety.
God’s Name is taken in vain—when we use it without due consideration and reverence. Whenever we make mention of Him before whom the seraphim veil their faces—we ought seriously and solemnly to ponder His infinite majesty and glory—and bow our hearts in deepest prostration before that Name.
God's Name is not to be sported with and tossed to and fro upon every light tongue. O my reader, form the habit of solemnly considering whose Name it is you are about to utter. It is the Name of Him who is present with you, who is hearing you pronounce it. He is jealous of His honor, and He will dreadfully avenge Himself upon those who have slighted Him!
It has become almost impossible to walk the streets or to enter mixed company without hearing the sacred Name of God treated with blasphemous contempt. The novels of the day, the stage, and even radio (and more lately television, the cinema, and the press) are terrible offenders, and without doubt this is one of the fearful sins against Himself, for which God is now pouring out His judgments upon us.
God is dreadfully incensed by this sin, and in the common commission of this Heaven-insulting crime, our country has incurred terrible guilt! "The Lord will not hold him guiltless that takes His Name in vain." Sore punishment shall be his portion, if not in this life, then most assuredly so, eternally so, in the life to come!
