"Thou shalt not take the name of the LORD thy God in vain for the LORD will not hold him guiltless that taketh his name in vain." Exodus 20:7
The third commandment concerns our approach concerning the attitude we have for God. The name of God should be honored, glorified and protected. "That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth; And that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father." (Philippians 2:10-11)
God's name should never be used for any idle or insincere purpose. How often is God's name used to curse or as an expression of anger, and frustration! Often He is the subject of jokes and frivolous conversation. To use God's name with such disregard for His character, authority, and person is to elevate oneself above God. What person under the authority of God would speak of, or refer to, their holy King in this way?
Even unto his death he is blasphemed
And they crucified him, and parted his garments, casting lots: that it might be fulfilled which was spoken by the prophet, They parted my garments among them, and upon my vesture did they cast lots. And sitting down they watched him there; And set up over his head his accusation written, THIS IS JESUS THE KING OF THE JEWS. Then were there two thieves crucified with him, one on the right hand, and another on the left. And they that passed by reviled him, wagging their heads, And saying, Thou that destroyest the temple, and buildest it in three days, save thyself. If thou be the Son of God, come down from the cross. Likewise also the chief priests mocking him , with the scribes and elders, said, He saved others; himself he cannot save. If he be the King of Israel, let him now come down from the cross, and we will believe him. He trusted in God; let him deliver him now, if he will have him: for he said, I am the Son of God. The thieves also, which were crucified with him, cast the same in his teeth. Now from the sixth hour there was darkness over all the land unto the ninth hour. And about the ninth hour Jesus cried with a loud voice, saying, Eli, Eli, lama sabachthani? that is to say, My God, my God, why hast thou forsaken me? Some of them that stood there, when they heard that , said, This man calleth for Elias. And straightway one of them ran, and took a spunge, and filled it with vinegar, and put it on a reed, and gave him to drink. The rest said, Let be, let us see whether Elias will come to save him. Jesus, when he had cried again with a loud voice, yielded up the ghost. And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent; And the graves were opened; and many bodies of the saints which slept arose, And came out of the graves after his resurrection, and went into the holy city, and appeared unto many. Now when the centurion, and they that were with him, watching Jesus, saw the earthquake, and those things that were done, they feared greatly, saying, Truly this was the Son of God.
