THE LAW of God will always be The Gospel of God.
Hebrews 3:16 – Hebrews 4:2
16 For who, having heard, rebelled? Indeed, was it not all who came out of Egypt, led by Moses? 17 Now with whom was He angry forty years? Was it not with those who sinned, whose corpses fell in the wilderness? 18 And to whom did He swear that they would not enter His rest, but to those who did not obey? 19 So we see that they could not enter in because of unbelief.
The Promise of Rest
4 Therefore, since a promise remains of entering His rest, let us fear lest any of you seem to have come short of it. 2 For INDEED The Gospel was preached to us as well as to them…
Man shall not live by bread alone…
If you do not know The Gospel = THE LAW see here:
