With a handful of exceptions, Christians are overwhelmingly united in their willingness to worship God on the first day of the week. After all, we have been doing this for two thousand years, and we are rarely questioned about it. Why not just go with the flow? The answer to that question is that we should want to be deliberate Christians in everything we offer up to God. We never want to be guilty of the “will worship” that Paul condemns in Col. 2:23. We are constrained to offer to God what He requires of us, and not anything else. So why do we worship on the first day of the week? Why didn’t the Church remain with the seventh-day Sabbath of the Jews?
