Learning to keep Torah is a lifelong process. YahShua doesn't expect us to be completely conformed to the Torah overnight. Remember, in Acts 15, the early non-Jewish believers were given only four "rules" from the Torah as a starting place. The Jews knew that as the new believers attended synagogue and heard the Torah taught, they would gradually learn everything else.
I'd like to list here some of those commandments included in "everything else", which many people coming out of Constantine Christianity may not be familiar with. After I was convinced that I ought to keep Yah's commandments, I really didn't know where to begin. So in the interest of helping anyone else in that situation, I'll briefly sum up what I learned in the first year that I began to study Torah.
1. I highly recommend reading Leviticus 23 as a starting point. This chapter outlines the Feasts of YHVH and how to celebrate them. One of the most exciting elements about keeping Torah is observing the feasts.
2. Abstain from unclean foods. Basically this consists of pork and bottom feeders (such as crab, oysters, etc.). There are some other unclean animals but most of them don't make it into the typical American diet. Be aware of ingredient labels that list lard or gelatine. Not only will this lengthen your life and increase your health, but it will be a good way to discipline your flesh.
3. Come out of Babylon by ceasing to celebrate pagan feasts. Stop celebrating Christmas and Easter, feasts rooted in paganism. This will be one of the most obvious things that will separate you from the world and honor YHVH. Educate yourself on the roots of these pagan celebrations. You can find this information literally everywhere. A good starting point is Fossilized Customs.
4. Keep a kosher closet. This means to make sure all your clothing is made of unmixed fibers. In other words, no shirts or pants or socks that consist of less than 100% of anything. Two fabrics may be sewn together, but one type of fiber may not be woven with another (as in 85% Cotton/15% Polyesther). This will be a constant reminder that Yah expects you to remain unmixed from the world.
5. Wear four fringes or tassles, threaded with blue, on the four corners of your garments. These are called tzit-tzits, and are intended to be a constant reminder to keep the Torah. These fringes also provide an excellent witnessing opportunity wherever you go as people are bound to ask you why you have four fringes hanging from your waist.
6. Keep the Sabbath from sundown Friday to sundown Saturday. This is the true seventh day that was set-apart in the beginning. The Sabbath (Shabbat) will be an added blessing when kept on this particular day. Try it and see! You'll never want to go back to that old, pagan SUNday worshipping ever again!
These are only meant as starting points. You need to actually read the Torah (Genesis, Exodus, Leviticus, Numbers, and Deuteronomy) for yourself and, each time you read, absorb more and more of what following YahShua requires.
Again, keeping Torah is merely doing all you can to conform your life to what Yah wants you to do!
