The responses are cool! I thank everyone for their opinion and then some. ;-) Keep them coming!
I agree with the thinking that the ring does not justify your relationship. Married men SHOULD hold it down. But we live in a fallen world. And if all someone sees you do is walk down the street and get into your car, that's all they know about you. They see that ring, they take a second look and want to know more. Is your marriage falling apart like others around them or is it holding fast and true like it should.
Then they begin to take mental notes and see if we are the living testimony that God has called us to be. The fact God even trust us with the sacred institution of marriage is humbling. Is the ring biblical? No. Truthfully, I could not go into the history of it. But it is the evidence of marriage, the hope that there are those still true to such God and the marriage He's blessed them with. With so many people shacking up, it's hard to tell who's married and who's not. But if all someone sees if a man's left hand with a wedding band on it, it can make all the difference in the world. That band does not prove that it's a God-ordained marriage but it does open the door for that couple to a witness to the observer, whether they know it or not.
You'd be surprise who's watching you. I usually open the car door for my wife all the time. One of my older cousins observed this and said to his mother, "Wow, he really got out and went around the car to open the door for her." That opened the door for a conversation on respect, how to treat women, etc.
Nakia, you're right as well. Some men make excuses about not wearing it so they can still see if they "got it." That in of itself is an issue. Some thing they need to come to terms with.
But enough of this e-novel. Let me make room for other responses. (Was that good enough, sjonathan02?) Suffice it to say, I keep my ring on all the time.
