Since I took part in this experiment (albeit late), however before I read this post I'll respond in kind.
Some atheists on here rightfully felt that they weren't comfortable typing that in, because it is not what they believe. It's not because they are incapable of doing so, it's because they felt they would be making a dishonest statement.
I thought I saw where you were going with this, as I also know that piece of scripture. I clearly don't believe, however I also have no problems typing the words "Jesus is Lord" on request. I don't believe that to be true, however I can write those words out.
However, I can also type "Muhammad is Lord", "Zeus is Lord", "Vishnu is Lord", etc. It's all the same, none have any particular special meaning.
To help you gather data points, when I was very young my family used to go to church (Presbyterian) and at one point I considered myself Christian. However I was quite young, and simply believed because I assumed the things that I had been taught in Sunday School and whatnot were true. My family was never really religious and stopped going to church somewhere around the time I was age 8-10, and by the time I hit my teenage years I described myself as agnostic. Religion was never really a concern to me, I didn't necessarily believe anymore, but I considered it a bit of an open question.
I had my first girlfriend at age 17, and she happened to go to the church my family used to go to. So, I went along with her family to get more of a "grown up" perspective on things and to take a real look at it. I even got involved with the youth group for a time, and played a song or two for the congregation on clarinet as part of the music group. Overall, it was a fun time.
However, when I started examining the claims the religion made, and the associated theology, it raised some big credibility problems. However, researching things back in the late 90s and early 2000's wasn't as easy as it is today. The internet was a thing, but there wasn't nearly as much info, and the info that was there was harder to find. I knew enough that I came to definitively reject Christianity as it had been presented to me, but there were still a lot of unanswered questions about other possible interpretations, or even other religions.
I still referred to myself as agnostic in those days, simply because I didn't understand what an atheist was. I was going under the common, but incorrect definition that an agnostic is someone who doesn't have a belief either way, and an atheist is someone who thinks with 100% certainty that there isn't a god.
I can remember reading "The God Delusion" shortly after it came out, and became aware of the actual definition of atheism, which is someone that does not have a theological belief. I can remember thinking to myself "Oh, well in that case, I actually fit the definition of atheist". I've called myself an atheist ever since that moment. In reality, I was an atheist without knowing it back well into my teenage years, probably somewhere around the time I started calling myself agnostic, which may have been 14-15ish, however I can't really remember for certain.
Anyway, as you can tell, I never really went through an indoctrination. If anything, I had fun while I was affiliated with the youth programs at the church, but once I hit the age of reason I never really bought what they were trying to sell. Once I started trying to learn more about it, it became more and more unbelievable. It's remained somewhat of a fascination for me since those days however, I'm a bit of a history buff as it is, so I like reading into the history of the christian religion and where certain beliefs and ideas came from. There's a lot of interesting stuff out there, and occasionally on forums like this I'll hear a new perspective or idea I was not previously familiar with.
So, I don't really hold the bible in any special reverence. Scriptures, and words like "Jesus is Lord" are just that... words. There's no reason to believe some mystical spirit or force exists that would prevent me from typing them.
