I find it odd that you generate many posts about Sabbath and none (that I can recall) about Jesus.
The only true "rest" any of can have is because of Yeshua/Jesus, and IS Him. The only rest that's truly important in life is the rest from our own strivings and failings. The rest from the punishment and death that comes from our flesh. By His life, death and resurrection, we are able to be cleansed. Truly, His blood that covered my sin is what allows me to have right standing before God. It is His mark on my life. His sign. I'm broken, I'm humbled, and I'm grateful for the sacrifice that was made for me.
My entire life should be a sign of my thankfulness for that. Daily, I seek to have Him lifted up, glorified, and to see His Kingdom strengthened in me and in others. The Sabbath is a portion of that. It is a day that God set apart from all others. It's a day that God told His people to set aside, and worship Him, serve Him, and serve others. By honoring the Sabbath, even just physically, it provides us the opportunity to honor Him. Not the only way, but a way. It's a way to physically rest from our struggles because we know the only true rest is Yeshua. That's what we celebrate. Truly, as Paul said, the substance of everything, and this day, IS Yeshua.
Now you may disagree about keeping the Sabbath, or say that it's done away with, or that we're trying to earn our salvation. That's fine. You're entitled to that opinion. Heaven knows there have been enough threads lately where both sides keep promoting their scriptures and their reasoning and their opinions to support or thwart the Sabbath. Again, that's fine. Be fully convinced in your mind, by letting the Spirit teach you. Has He laid a physical sabbath on your heart? Obviously not. Has He laid it on mine? Obviously so. I don't judge anyone for not keeping it. I trust that God's people are being obedient to the things He's laid on their heart. And I respect and appreciate that.
These threads that I post every week are meant to be an encouragement to those celebrating the Sabbath. That's something God laid on my heart to do when I joined this forum. To weekly, encourage this little "cult"
Hebrews 3:13 "But encourage one another day after day, as long as it is still called “Today,” so that none of you will be hardened by the deceitfulness of sin."
Thankfully, the Sabbath is also "today".
