to him who knows to do good and not do so, to him it is sin.
sin is way more than law and command keeping.
and gentiles were never
right. sin exists today.
you see, when Jesus finished the Sermon on the Mount. he said " you shall be perfect .... ).
so, you see, the actual definition of sin is " missing the mark, falling short of a standard ".
so, if you fall short of the standard that Jesus laid out in that sermon , then you are in sin.
the Sermon on the Mount is telling us how to do good, as God is good.
so, knowing to do this and not doing so is sin.
no Sabbath keeping involved.
Know to do good?
This comes from studying the word and the moving of the Holy Spirit. Not just one sermon from Jesus, or we wouldn't need the rest of the bible. When Jesus was tempted He quoted scripture.
Matt 5:27,28 Ye have heard that it was said by them of old time, Thou shalt not commit adultery: But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
By studying the scriptures i come to know what is right and wrong for me.
Isa 8:20 To the law and to the testimony: if they speak not according to this word,
it is because
there is no light in them.
As i have studied i have been convicted to obey the Sabbath because it is right.
Not to be saved but because it is the good thing to do.
That means it is sin for me to not obey.
Rom 3:20 Therefore by the deeds of the law there shall no flesh be justified in his sight: for by the law
is the knowledge of sin.
Christ is my righteousness not the law. Christ perfectly obeyed the law because He followed the Spirits leading. I want to follow Jesus.
