Sabbath a law or a good tradition?

Exodus 31:12 The Lord then gave these instructions to Moses: 13 “Tell the people of Israel: ‘Be careful to keep my Sabbath day, for the Sabbath is a sign of the covenant between me and you from generation to generation. It is given so you may know that I am the Lord, who makes you holy.

The Sabbath Day, God's day of rest at creation and later commanded by God for Israel to observe, this very day was given to man (Mark 2:27), specifically the Jews as a law, but in general as an example of Sabbath to everyone else, of resting and noticing and taking in "it is good" all the goodness of God, hearing and reading of all He has done. Sunday became the Christian sabbath, the first day of the week, celebrating our set aside time for God on the day that Jesus rose from the dead. But, Chrisitan tradition as sweet as that tradition is, not to be mixed up with the Sabbath law to the Jews. That special day was a sign between God and His people Israel. The concept of following this law, in a non legalistic way is still acceptable and a good thing, and I think that's one reason why the early church followed this pattern, and passed it on to continue having one special day that was important for God in your life. I believe Sundays are vital for the flock to hear the same marching orders, what the Spirit says to the churches, on the same day of the week, every week, but it's nice it's not like the Jewish law through Moses, but more on the voluntary basis, just in case your boss made you work a few Sundays, you're not at odds with God. Though I will say, I still will hold to good arguments of coming together on the first day of the week, but with an understanding heart toward any unknown unforeseen particulars, like hospital stays, vacations with no church gathering available, etc. Sabbath doubting brethren, just use Sunday gatherings as your easy standard to follow, a simple rule of thumb, so you won't procrastinate or get lazy with the things of God, nor your relationship with Jesus. let the day work for you, so you'll always, each week be reminded that you have an appointment and time set aside to find rest for your soul in Him, as fellowship, prayers, the breaking of bread and the apostles doctrine, still and quiet your soul and instruct you in the words and the ways of His righteousness.
