I understand your point, and I agree that Jesus’ teachings should come first. ❤️

But John 14:15 says to keep His commandments; it doesn’t specifically say “keep the Sabbath.” Jesus kept the Sabbath, but Scripture also records His resurrection and appearances on the first day, and believers gathering then (John 20:19; Acts 20:7).

So I think we should look at the whole of Scripture rather than assume that one practice settles the question. We may understand it differently, and that’s okay. 🙏🏽
