“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” (Exo.20:7).
What is this NAME that we should not take in vain? A “name” in God’s economy of words is not merely a label for identifying things or persons. A name is a testimony of a character. Remember when Jacob wrestled with that angel? He said, “Thy name shall be called no more Jacob, but Israel, for as a prince hast thou power with God” (Gen.32:28). Remember Simon who after receiving and speaking a revelation had his name changed to Peter? A name was a testimony of what had happened, or a life which had been lived.
Likewise, God’s name is a testimony of His Character. As a Saviour He has been revealed to us in the Lord Jesus Christ. When we get baptised in the Name of the Lord Jesus (Act.2:38) its a testimony of having died to ourselves and rising to live by the testimony of God’s life, His Name!
Thus, to take on the name of Christ but yet live a contrary (sinful) life IS TO TAKE THE NAME OF THE LORD IN VAIN. Isnt that what Proverbs 30:9 tells us – “…lest I be poor, and steal, and take the name of my God in vain“? Yes, when we lie, steal, and do all such sinful acts WE TAKE THE NAME OF THE LORD IN VAIN! Therefore, “Let every one that nameth the name of Christ depart from iniquity” (2 Tim.2:19)!
