“There remains therefore a Sabbath rest for the People of God. For the one who has entered His rest has himself also rested from his own works as God did from His.” Heb.4:9,10
I realize I won’t change your mind, but this is saying that the Sabbath is not a day but a state of being. When you cease relying on your own righteousness (works) and rely on God’s provision (His Son), you enter the Sabbath rest.
The law never set anyone free. It can’t. No one can keep it. (If you say you can, you are lying). It can only condemn and point to your need for Christ. Christ is the end of the law for those who believe.
“Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them.” Matt 5:17
Ending something vs. fulfilling (as in fulfilling an obligation or requirement) seems to be an important distinction. If the law is ended and I am released from any obligation to it, does that mean I am now free to kill or steal with no consequence as to my salvation or relation to the Creator of those laws?
I can show you that you don’t really hold that position, because, but you do believe that murder is still murder, post-cross.
The only way you can possibly know that murder is inherently wrong is that a law must exist before it can be broken. Otherwise, no law and there is no law to break.
I don’t expect to convert you either, which is Paul’s point.
We are all on individual journey’s, starting at different points and moving at individual rates. The only thing certain is that we are all headed to New Jerusalem and only there will all things become crystal clear and unquestionable.
Until then, there are going to be points that each of us think are going to be correct. We are all going to be wrong somewhere, which is why we need Christ to cover our shortcomings.
