Make it special. Enjoy a sliver of the best of life. It is a rehearsal for the Millenium. I am not trying to push it and certainly not mandate it, but at some point I dress up a little, wear the fine threads, we eat special foods that we usually don't eat the rest of the week, The boob tube stays off....not because it's a sin to turn on electricity...but because it's a day that is supposed to be set apart...TV is just one big vulgar grotesque worldy distraction. It would be best in my opinion if everyone threw the hypno-box out the window...but if you can't bear that...perhaps try to set the sabbath apart. Sing, recite psalms...be joyous. Let me explain this better. I am a farmer. Everyday I wear dingy old clothes that are stained and tattered. Wearing nice clothes is My way of setting it apart, my way of remembering I am resting on this day...and showing others that it's a day of rest. The whole point is setting it apart. Another good way to start learning how to walk in the way you have said you want to walk is to get it directly from the source. Acts 15 comes to mind:"[21] For Moses has been preached in every city from the earliest times and is read in the synagogues on every Sabbath." It was obviously expected that the Goyim coming into faith in Messiah of Israel were going to be sitting down and learning Torah (and Nevi'im and Ketuvim) every week.
You can look into the weekly parashot (Parashah-singular). These are bite sized portions of the Torah. They are read every week. They are also attached to Haftorah and Messianics have New Testament readings attached to the Parashot too. You can read and reflect on everything that that passage has to offer...from the practical to the spiritual. I am not trying to confuse you but I am probably doing a wonderful job. There are two types of Parashah schedules. There is the annual cycle...in which you can get through the whole Torah in one year. Then there is the Triennial cycle in which it takes 3 years to get through all of the Torah. Both have their advantages and disadvantages. I am really starting to appreciate the triennial cycle however because the passages are smaller and you can focus your attention more finely. If you type these terms in to google you can get schedule lists quite easily. If you have family or people you can have sabbath with, offer insights ask questions, discuss.

You don't have to become a "Jew"* practicing "Jewish" religious rites, but tradition isn't always a bad thing. I don't think Yahushua was against tradition and He probably applied much of it either incidentally or approvingly. He was only against tradition and pharisaic halakha (the way one practices Torah-Literally, the way one walks) when it went against Torah or was given the same status as Torah (as legally binding...i.e. washing of the hands). It offers a continuity that people in some ways need. There is nothing wrong with reading the creation account every week or saying a blessing over your family, your sons, your daughters, wives or husbands, doing a traditional blessing and thanksgiving over bread and wine (doesn't have to be Challah...but then again there's nothing wrong with Challah...but if Challah becomes a religious mandate then it becomes a problem. For the sake of information, Challah is not a universally practiced tradition. It is predominately Ashkenazi with some Sephardics practicing it as well, but for example the Mizrahi use flat breads for sabbath...if I had to bet, I would bet that Yahushua's and ancient Israel's practices were closer to Mizrahi and Yemenites than other communities...just a guess), or going out and looking for the first 3 stars in the night sky to mark the end of Sabbath....and other such things. Right after Sabbath is over, my wife and I usually talk about the week, what we did right, what we could have done better on, what we want to do in the coming week both in the horizontal world and in the realm of the vertical. That's our traditional post sabbath conversation. That's what we do...find your own way. :)

*when I say Jew, I am not referring to blood or ancestry or the term Yahudi, but moreso in the sense of the practices of Rabbinic Judaism
