That is where grace ends.
Yeshua always said “go and sin no more” after healing.
Was he making an impossible demand, or is Hebrews 6 factual?
Hebrews 6:
[1] Therefore leaving the principles of the doctrine of Christ, let us go on unto perfection; not laying again the foundation of repentance from dead works, and of faith toward God,
[2] Of the doctrine of baptisms, and of laying on of hands, and of resurrection of the dead, and of eternal judgment.
[3] And this will we do, if God permit.
[4] For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost,
[5] And have tasted the good word of God, and the powers of the world to come,
[6] If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of God afresh, and put him to an open shame
So you go to to Jerusalem three times a year right for those feast ?
Your not keeping them and you are changing the definition of grace.
Since you brought up the book of Hebrew why don’t go ahead and read Hebrews 7 cause that right there explains why you can’t keep them all .
The moral aspect of the Torah is for your own good
Read Matthew chapters 5 through 7 and the moral aspects are in there .
Paul talks about it in Galatians (go back and you will I gave you the scriptures)
Before you keep this up go read Acts 15
