Perhaps it would be helpful if you explained what you mean by this. There are plenty of laws that are not possible to follow specifically with sacrifices.
Mixed garment clothing also comes to mind but this one is "possible" it's just crazy difficult solo. Unless of course you make your own clothes. Do you want to go down the list of 613? laws and say which ones are to be followed and which aren't?
You haven't posted enough for me to gauge whether you mean this or not so I'm not meaning offense here
Even when the law was first given to Moses, many of them could not be obeyed, and not even Jesus obeyed the laws in regard to having a period or to giving birth. For example, the Israelites were given number of the laws had the condition “when you enter the land…” while they were still wandering the wilderness for 40 years, so there is nothing wrong with not following laws that can’t currently be followed. Likewise, a large portion of the 613 laws was given to govern the conduct of the Levites, which the other Israelites were not permitted to follow. In 2 Chronicles 30:15-20, Hezekiah prayed that God would pardon all who seek Him with their heart even though they were not acting in accordance with the sanctuary’s rules of cleanness. When the exiled in Babylon, the condition for them to return to the land was to first return to obedience to the Mosaic Law, which contained laws that require having access to the temple that had just been destroyed, so God honored their obedience to the laws that they were able to obey. This was taught to early Christian:
Didache 6:2 For if you are able to bear all the yoke of the Lord, you will be perfect; but if you are not able, what you are able that do.
Some of the Mosaic laws were only given to govern the conduct of the King, the High Priest, priests, judges, men, women, children, widows, those who are married, those who have servants, those who have animals, those who have crops, those who have tzaraat, those who are living in the land, and those who are strangers living among them, while others were given to everyone. So while there are illegitimate reasons for not following a particular law (James 2:1-11), there can also be legitimate reasons.
Remembering the Sabbath and keeping it Holy is a personal decision, I don't have any issue with that..even if it's done "religiously" (unintentionally) if you stay in prayer about it, I think the Holy Spirit will open your understanding to what it means for each of us personally. It could be that the temptation to fall into a religious spirit is very real for a person and it's probably best that they don't "keep the Sabbath" and consider each day "holy alike"
There is a sense that it is a personal decision to choose whether to refrain from committing murder, idolatry, adultery, theft, breaking the Sabbath, rape, kidnapping, and so forth for God’s other commands, but that doesn’t change that we are ultimately obligated to obey God and that it is a sin to disobey Him. Jesus set a perfect example for us to follow of how to practice Judaism by walking in sinless obedience to the Mosaic Law, so he had much more of a religious spirit than even the Pharisees did. A day that is holy is a day that is set apart and in order for a day to be set apart there needs to be another day that it is set apart from, so to treat each day holy alike is an oxymoron and to treat each day the same is to treat none of them as holy.
There is nothing wrong with understanding the "heart" of the law (why it was given and how it points to Jesus) or whether some practices promote holiness in your life.
even phylacteries sound like an excellent practice (binding certain scriptures as a frontlet between your eyes). I've seen people hang scripture in their house or paint it on their walls. It does something for sure. When I'm in a black mood, seeing a scripture verse on a plaque does "something" positive. Practically I think this "echoes" the purpose of biding scripture.
I didn't choose it but currently above the mantel where I live is the Micah 6:8 passage about walking "...humbly with thy God"
Which was a verse that occasionally came to me when asking for direction and the frustration at that being the only answer (before the plaque)...and yet submitting ourselves IS direction especially when we find ourselves exalting/questioning God. There is a proper method to seeking his will and it's not questioning God (Romans 9:20)...doesn't end well and won't get you what you really want/need.
The heart of God’s law is to teach us how to know, love, worship, believe in, and testify about Him and Jesus through practicing His character traits, which is eternal life (John 17:3) and Gods had straightforwardly made His will known through what He had commanded in His law (Psalms 40:8).
