If God changed the Sabbath day, wouldn’t it be in His word somewhere?
If God had changed something so important as one of His 10 commandments, He would surely tell us about it. The Bible tells us that God does nothing unless He first reveals it to His people. If there is a Bible verse that says God changed the Sabbath to to Sunday, we’re going to find it as we search every text that mentions the first day of the week.
After an exhaustive search using a concordance, we find that the word “Sunday” is not in the Bible. The day for Sunday is always called "the first day" and it is only mentioned 9 times in the entire Bible. We'll take a close look at each of these nine times in our study.
