"And to whom did he swear that they would not enter into His rest, but to those who did not obey? So we see that they were unable to enter in because of unbelief. Therefore, since a promise remains of entering into His rest, let us fear lest any of you seem to have come short of it."
We sin because we don't have faith in Yahuah, because we don't fear Him!
We Fear (worship) ha shatan when we sin (disobey Yahuah).
Follow the examples that he has already given. Remember those who were allowed to enter His rest (land/shabath/coming reign). It was only 2 from the original crew that left Mytsraym and their little ones. They had to WAIT till the rest died off to do so.
Do not be faithless-unbelieving-provoking-scorning-quarreling with Yahuah. Don't harden your hearts! Have a heart of flesh.
