Where does He tell us not to?
1Pe 2:21 For even hereunto were ye called: because Christ also suffered for us, leaving us an example, that ye should follow his steps:
We should follow in His steps. (But not do what He did?)
What did He do?
Luk 4:16 And he came into the Nazareth, where he was having been brought up; and entered, according to the custom to him in the day of the sabbaths, into the synagogue; and stood up to read.
What did Christ say about the Sabbath?
Mar 2:27 And he said to them: The sabbath because of the man was made, not the man because of the sabbath.
Mar 2:28 So that a lord is the son of the man even of the sabbath.
He didn't say "Oops, I made a mistake back there during creation week." now did He?
the example of Paul was to keep the Sabbath...
Act 17:2 And Paul, as his manner was, went in unto them, and three sabbath days reasoned with them out of the scriptures,
And the writer of Hebrews plainly tells us to keep it...
Heb 4:9 There remaineth therefore a rest to the people of God.
And we know what the word for rest here is, it is Sabbatismos...
The Diaglott translates this...
Heb 4:9 Therefore remains a keeping of a sabbath for the people of the God.
My Oxford Bible has "keeping of a Sabbath" in the margin here.
Now show me all the scriptures that say "don't keep the Sabbath, rather keep Sunday".
