I have heard, and used myself, so many different excuses over the years on why Christians do not follow the 4th Commandment. I could do several comics on just the different ones, but the answers (the right side) would still be the same. There isn’t anywhere in the Bible where it tells us to stop obeying the Sabbath commandment. It doesn’t matter that there are no examples before the Exodus of people keeping Sabbath, or that after Jesus rose there is one instance of people gathering together on the first day of the week, or that the early “Church Fathers” wrote about observing the first day. The Sabbath is the Sabbath, it hasn’t changed. I included those verses that describe the Millennial Reign to show that in the future, it will still be kept. If it was kept before us, and it will be kept in the future, why don’t we keep it now?
I don’t know about everyone else, but when I read the Bible and something is preceded by “And the LORD said”, I hold that in higher regard to anything else. If something comes straight from His mouth, that is what we follow. It doesn’t matter if we read someone else (Paul) and it seems he is saying something totally opposite of what was spoken out of the mouth of God. We follow God, not our misunderstanding of Paul (2 Peter 3:16). I have read from cover to cover, I cannot find where it says “And the LORD said … You no longer have to observe the Sabbath.”
