Have you ever heard the following argument?
Joshua 10:2-13 speaks about God stopping the sun in “the midst of heaven” for a full day. This event affected the weekly cycle and moved the Sabbath from Saturday to Sunday!
We have. Yet, while there are many ideas on what really happened in Joshua 10, we suggest to just read it as it is. God performed a miracle that day, but the question is… did this affect the Sabbath day?
If this event affected the Sabbath day then it must have also, obviously, affected the rest of the days of the week. But to answer we have to go back to what the elements of the sky, like the Sun, are used for. Genesis 1:14 says:
“And God said, let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years.”
The sun, moon and stars are used to determine "times." So when the sun was stopped that day, that means that time also stopped. Meaning that the days (or time) did not change at all. Saturday did not turn into Sunday, nor did Wednesday turn into Thursday, because all the elements that determines the times just “stopped.”
If one believes this event changed the Sabbath from the seventh day to the first day, then that person is bound to answer the following two questions:
1) If the Sabbath has really been moved to the first day of the week, why then are the followers of Christ observing the seventh day saturday? (Mark 15:37, 42; 16:9; Luke 23:56; 24:1).
2) If the times changed that day then why does the Jewish nation today still observe Saturday as the Sabbath and not the first day of the week?
There really isn't much to say here, because it’s obvious that if the Sun stood still, then so did time, and thus no change in the weekly cycle can possibly take place.
