I wish you blessings in that. I tried it and found it to be cold and not for me. It was like I was trying to be something I was not (like a Jew?) This was over a period of some 5-10 years. It never 'took'. I finally went back to being a plain ole Christian and am much happier. I do like to study the Feasts of Israel. But that is as far as it goes now. Sunday is the Lord's day and the Shabbat is still the Shabbat...they were never meant to be the equivalent days. People need to stop trying to make them so. It can cause so much sorrow as it did for me. Same thing for the holidays. Live and let live.
Do not demand everyone worship the same way, for they both worship the Lord and He is well pleased.
There is absolutely nothing what so ever wrong with worshiping on Sunday.
The problem is when one attempts to supplant Sabbath for a so called "Lords day"
One simply can not point to any scripture that declares Sabbath is put aside. Extraordinary claims require extraordinary evidence. The theology of Sabbath is put aside for the "Lords Day" utterly fails this evidentiary test. Even the most ardent Paulian doctrine that supposedly supports that thesis relies on indirect, mury distortions of the teachings of Paul and rely heavily on ignoring clear warnings of scripture namely:
2 Peter 3:14-16 Therefore, beloved, since you look for these things, be diligent to be found by Him in peace, spotless and blameless, and regard the patience of our Lord as salvation; just as also our beloved brother Paul, according to the wisdom given him, wrote to you, as also in all his letters, speaking in them of these things, in which are some things hard to understand, which the untaught and unstable distort, as they do also the rest of the Scriptures, to their own destruction.
I am sure you are saying that you are being "Led by the Spirit" There is however a very serious problem with your stance.
If indeed you are being led by the Spirit, WHERE is the Spirit leading you? Doesnt scripture state that the Spirit will lead you in all truth?
WHAT IS TRUTH? What does SCRIPTURE have to say about what is truth?
Your righteousness is an everlasting righteousness, And Your law is truth.
The sum of Your word is truth, And every one of Your righteous ordinances is everlasting.
Thou art near, O Lord; and all thy commandments are truth.
So, we see that the Law/Torah/Commandments
IS TRUTH
So if indeed you are LED by the Spirit he will lead you to the Torah.
You can not say that you desire to be upright, walking in holiness and reject the Torah. Such a statement is self deception. If indeed you TRULY seek holiness you will find yourself delighting in the Law as David proclaimed.
More scripture regarding the Law:
Praise the LORD. Blessed are those who fear the LORD, who find great delight in his commands.
I rejoice in following your statutes as one rejoices in great riches.
My son, give me your heart and let your eyes delight in my ways,
But his delight is in the law of the LORD; and in his law does he …
Here is what Paul has to say about the Law.... For I delight in the law of God after the inward man
