Love to hear from you man! It's been a minute :)
Why is a great question! For me, it's because I love my Lord and Saviour. And He says in John 14:15, if you love me, keep my commandments. So it's obedience out of love.
As for people ignoring it, that's a whole other conversation lol Sunday instituted by the pagan Romans to get away from the Jews. Huge history on it, it's pretty telling.
But that being said, there's a blessing attached to it. Sabbath from everything of the world. Complete rest, no stress :)
I had a coworker who would get saturdays off due to his faith... I remember thinking (what an awesome trick!) lol
But, on a serious note. I did learn recently about the Pagan adaptation, but as you said, of all the thousands of denominations of Christianity, they only agree on one thing; Christ. The rest is all over the place, almost.
Good to see you are still around brother, this place always needs kind people like yourself.
Cheers
Yeah man, still here. Not as much as I used to be, but still hopeful that one day this stuff will moon LOL
