Taking the Name of God

Everyone is familiar with Exodus 20:7 - "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." - NKJV
And of course, it's one of the Ten Commandments.

When I do my bible studies, I usually look up the simple definitions and synonyms of the words used in the verse.

This scripture, for most, has always meant something on the lines of - "Thou shall not swear or curse." When I was a kid I never understood where people came up with this translation. But then I read another translation of the verse that said, "You shall not misuse the name of the LORD your God." - and using God, Christ and Jesus as swear words are most definitely misusing Christ's name.

But...
I know several years ago, our pastor or one of the elders or just someone (I really can't remember) brought to my attention that this may have a different meaning. I remember doing my own bible study on it not long after that discussion and was just reminded of it recently.

First: Take - to hold, grasp, or grip, to receive and accept willingly, to carry, to occupy, to adopt...
Second: Vain - ineffectual or unsuccessful; futile; without real significance, value, or importance; baseless or worthless, useless...

While I was studying this, I began thinking of a bride taking the name of the groom. For example, my sister is about to marry, Shay Hayes. She will no longer be Lindsay Faught. She is taking his name as her own, because they will now become one. Lindsay Hayes.
Everyday, we take on the name of Christ. How? It's simple - by calling ourselves "Christians." We are taking the name of our Father as our own.
Now... here comes the Vain part. When we walk in unrighteousness, we are walking in worthlessness. By calling ourselves sons and daughters of God, but treat His name as if it were nothing, He will not hold us guiltless.
What comes to mind now is that a covenant is made between the bride and groom to love, honor and obey. When a person in this kind of covenant turns to another outside of this covenant - to me, this is counting the unity and bond that was made, vain - worthless, futile, without importance.
So as we make a covenant with God, saying that we will love, honor, and obey - yet we turn to another (sin), that is counting the covenant we have made with Christ as nothing.

I don't know if this makes sense to anyone, but it does to me. It just shows me how important it is to take on the name of our Father, and how we need to strive to be just like Jesus - perfect and holy. I know we're going to make mistakes, but that's where God's love and forgiveness comes in, and we can be washed clean and began again. We need to consider the covenant we have made with God as of the greatest importance. No one wants to be in a one-sided relationship. So how do you think God feels?
