I've never seen that verse as implying observance to Jewish laws (Torah). My understanding is it refers to the commands that the Messiah gave through the holy spirit to the apostles.
Matthew 28:18 And
Jesus came and said to them, “All authority in heaven and on earth has been given to me. 19 Go therefore and
make disciples of all nations, baptizing them in the name of the Father and of the Son and of the
Holy Spirit, 20
teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”
He said to teach all nations in the world as I have taught you. That Messiah himself instructed the nations
through the apostles to observe all that he had commanded them.
Acts 1:1 In the first book, O 1Theophilus, I have dealt with all that
Jesus began 2to do and teach, 2 until the day when 3he was taken up, after he 4
had given commands 5through the Holy Spirit to the apostles whom he had chosen.
Here I find the text plainly stating that it was the Messiah who gave the commands through the Spirit to the to the apostles. And here is what Peter stated the Messiah commanded him.
Acts 10:42 And
he commanded us to preach to the people and to testify that he is the one appointed by God to be judge of the living and the dead. 43 To him all the prophets bear witness
that everyone who believes in him receives forgiveness of sins through his name.“
I see Him commanding the apostles to preach and testify that Yeshua is the one appointed by God to be judge of the living and the dead, he is God in the flesh.
So through these verse I can see that it is through the Holy Spirit that we have a relationship with the Father, by honoring the One He sent, his Son, Yeshua the Messiah. I understand by this that we honor him by believing in Him, what he did, who he is, and what he will do. His instructions can be summed up in two statements. Judaism calls it the Shema v’Ahvata. The first states that there is no other God besides the God of (Israel) Abraham, Issac and Jacob, and the second declares our unending, unfathomable, love for Him, and his command that we should love others, as he loves us.
Faith, honor, hope=Love=The commandment.
When others attempt to twist this truth into observance to Jewish laws I do believe it is they who are not understand the true meaning of Torah. For me, Torah is fulfilled in those who love not those who observe laws because they have been fooled into thinking such observance means or leads to the forgiveness of sins. Forgiveness of sins is only administered and received by faith through love. Without love we have nothing at all. No matter how much we 'believe' our observances will be honored by God. They are not the means, nor the goal of our salvation. Not according to what I've been taught by the holy spirit.
