It is simple. Saturday is the day the Lord rested from creation.
Sunday is the day Jesus overcame death for all of us! As a result, we have entered into HIS rest. Every day is a Sabbath’s day to us because WE have ceased from our labors in trying to earn salvation and rest in HIM.
The Saturday sabbath is as outmoded as the daily sacrifice at the Temple.
We gather on Sunday, not to honor Sunday but to remember the LORD overcame death on that day.
Saturday originally never had anything to do with sacrifice, it was a day of rest.
The early Christians held service on the first day of the week for two reasons,
1 in respect of the Sabbath.
2 in honor of the resurrection.
We can worship any day, we can rest any day.
Yes every day is a Sabbath but not the Sabbath
God rested on the seventh day, he called it the Sabbath it is history.
So we agree that every day can be a Sabbath, but the ones calling Sunday the Sabbath are still under the same law but just using a false Sabbath.
The Sabbath of the pagans.
