Hey there 38!
First off, let me say welcome to the Forums! It's a pleasure to have you here, and I look forward to getting to know you.
I'm not sure how much searching of past threads you've been able to do since you been here, but this is a thread that I've been doing for several months now, every Friday or Saturday. Many of us in here celebrate a physical, 7th-day Sabbath. We don't do it for righteousness's sake. We don't do it because it makes us better than anyone else. (There may be a few Sabbath-keepers who think differently about that, but that's a different issue). We celebrate the Sabbath because God laid it on our hearts. We believe God gave the Sabbath to His people as a blessing, a day to rest physically and spiritually. With Jesus as our Savior, we are able to rest in the work He did to cleanse us from our sin and make us right with Him. Our keeping of a physical Sabbath is a sign and a reminder of that work.
There are several people in these forums, both pro-sabbath and anti-sabbath, who really like to argue about it. There are a "plethora" of threads that debate and argue about the Sabbath. The threads that I post every Friday/Saturday aren't meant to do that, but instead to be a blessing to those that do. It's always been my hope that it would stay that way, but there's usually a couple of people that come in to derail these threads with arguing, instead of keeping the them to the myriad of other threads dedicated to debating the Sabbath. Oh well, such is life.
I'm not saying all this to correct you or argue with you, I just wanted to explain what I try and do here. I try as much as possible to stay away from the Sabbath-debates. They rarely bare fruit, and usually cause even more division among the Body. (Although sometimes I get sucked in for awhile, and then have to quietly bow-out because it's a fruitless endeavor.)
So whether you keep the Sabbath or not, it doesn't really matter to me. The only thing that matters to me is that we worship our Creator and Savior in a way that is pleasing to Him. If He's laid on your heart to keep the Sabbath, awesome, go for it. If He hasn't laid on your heart to keep the Sabbath, then don't worry about it. The more that we all can focus on our God, the better off we, and the Kingdom of God will be.
Peace,
Matt
