You do not take up the Name of your God YHWH for a vain thing, for YHWH does not acquit him who takes up His Name for a vain thing.Exodus 20:7
Those who belong to the kingdom of God should be honoring the Name, or character, of God with their thoughts, speech, and conduct. This is appropriate and expected kingdom behavior.
This verse has classically been used throughout generations for the purpose of not abusing or misusing the revealed Name of God, in the sense of using it as a curse word, or speaking it casually in conversation outside of an appropriate worship setting.
But that misses the intent of what God is attempting to teach us here, and throughout the Bible. The real sense of the passage is less about misusing God’s name carelessly, and more about our character in claiming to be believers or followers of him.
To “take God’s name in vain” is not expressly to use it flippantly (although that certainly in included). To “take” his Name is to take up, or carry his Name as identifying who we are, or rather, whose we are.
For example, when a wife has historically taken the name of her husband, she has identified with the honor of his family line. In the same sense, when someone comes to the knowledge of God and wants to be his follower, then they take his Name, identifying with his character. As God’s children, we carry his Name and his character in this world.
The admonition here is not to abuse God’s Name, but it’s about when we are identifying as belonging to him, we do not dishonor or defame his Name or character by our careless conduct. This could be paraphrased as “You shall not take my Name lightly or for no purpose.”
Our desire to follow his ways should not be rooted in our own selfish ambition or schemes. We should not join the kingdom impetuously, without any real thought for the responsibility we bear. Instead, we should be sincere in our desires to live for him and to bring honor and glory to his Name. When we carry his Name, our actions and our words should match his.
Yeshua demonstrated this so completely that it was impossible to distinguish between him and his Father.
John 5:19 – So Jesus said to them, “Truly, truly, I say to you, the Son can do nothing of his own accord, but only what he sees the Father doing. For whatever the Father does, that the Son does likewise.
John 7:16 – So Jesus answered them, “My teaching is not mine, but his who sent me.
John 12:49 – For I have not spoken on my own authority, but the Father who sent me has himself given me a commandment–what to say and what to speak.
John 14:8-9 – Philip said to him, “Lord, show us the Father, and it is enough for us.” Jesus said to him, “Have I been with you so long, and you still do not know me, Philip? Whoever has seen me has seen the Father. How can you say, ‘Show us the Father’?
When we consider following the Messiah, we are accepting that he was sent from the Father, and carried the Name of God so completely that he was essentially indistinguishable from the Father. If we are to become more and more like Messiah, then this same characteristic should be evident in our lives. When people see or hear us, they should be seeing what the Father would want to do or say in that situation.
Does this sound like a heavy responsibility? Of course, which is why we should not take his name lightly or for no purpose. We are admonished by Yeshua to count the cost of kingdom living (Luke 14:25-33), but in so doing, to accept it willingly and gladly .
