Have you come up why as an "Christian" you have never kept the Sabbath(Saturday, not Sunday) holy as Jesus, Moses and Abraham did?

Sure!

The LAW was given to the CHosen People: the Jews.

I am a gentile.

Read Acts 15^th chapter.

[RedMonqey]

Read Acts 15th

So Acts 15 abrogates the Law of God, written by the Hand of God on Mount Sinai?

By omission?

Well that’s must come as a relief to those who don’t like the constraints of the Ten Commandments

Of course, Acts and Paul says no such thing just as Acts does nothing to change the Sabbath to Sunday

Paul is simply reassuring the uncircumcised gentiles who are concerned about circumcision, the ceremonial laws and ceremonial sacrifices (the Laws of Men) and not to be” burdened” by them as they are no longer necessity because of Christ’s sacrifice. .

Most of those who defend first day Sabbath go to Colossians 2:16. But even there it does not declare a change in the date of the Sabbath, just how one goes about keeping it.

No, the Sabbath was changed but by those outside the wisdom of the Bible and with more worldly reasons.

Try again.

The LAW was given to the CHosen People: the Jews. I am a gentile.

As am I

Under the New Convenant, Jesus and died for all and gave the Law Of God to all who will accept him as Christ the Savior.
Jews don’t necessariliy get any special privileges for being the Chosen People in the New Testament.

Jesus is the Messiah predicted in the Old Testament and the he is the fulfillment of the law and the prophets See Hebrews 7-10

But that's just going by The Book(as you insist)
