How do you observe the Shabbat (Sabbath) Day?

Observing the Shabbat is one of the major signs that identify an individual as one of the children of Yah and of Israel (Exodus 31:13-18).

People, who are not part of the 12 tribes of Israel (britam.org), become part of Israel by accepting the King of Israel (the Messiah - John 1:49) as their Master and Savior. If someone is your Master, then you obey him (Ephesians 2:11-12). The Messiah is the King of Israel and any King has laws or instructions for his subjects to follow (Deuteronomy 17:18-20). The children of Israel follow the Messiah and obey the commandments just like He did when He was on the earth (1 John 2:3-6; John 14:6; Luke 4:16; John 15:10).

The Bible gives us an idea on how to observe the Shabbat.

"If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the LORD, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words: Then shalt thou delight thyself in the LORD; and I will cause thee to ride upon the high places of the earth, and feed thee with the heritage of Jacob thy father: for the mouth of the LORD hath spoken it." (Isaiah 58:13-14 KJV) 

“Speak to the children of Yisra’el, and say to them, ‘The appointed times of Yah, which you are to proclaim as set-apart gatherings, My appointed times, are these: ‘Six days work is done, but the seventh day is a Sabbath of rest, a set-apart gathering. You do no work, it is a Sabbath to Yah in all your dwellings.”  (Leviticus 23:2-3 The Scriptures)

You should not buy or sell on the Shabbat (Nehemiah 10:31; 13:15-21) and you should do good on Shabbat (Matthew 12:1-12).
