Jeremiah 31:31 See, the days are coming, declares the Master that I will make a renewed covenant with the house of Israel, and with the house of Judah:
Jeremiah 31:32 Not like the covenant that I made with their fathers in the day when I strengthened their hand to bring them out of the land of Egypt, my covenant which they broke, although I was a husband to them, saith the Master:
Jeremiah 31:33 For this is the covenant that I will make with the house of Israel; After those days, declares the Master, I shall put my Torah in their inward parts, and write it on their hearts. And I shall be their Elohim, and they shall be My people.
Ancient Israel failed because the majority of them did not have His Spirit – only the elders, priests, prophets, kings and a select few picked for leadership positions ordained with the Laying on of Hands.
See Deuteronomy 5:29 Oh that they had such a heart in them, to fear Me and to guard all My commands always so that it might be well with them and with their children forever!
It takes the power of His Spirit to keep His laws.
These verses substantiate what I have already said – man can’t govern himself without the Creator, His Spirit, and His laws.
Jeremiah 17:9 The heart is crooked above all, and desperately sick, who shall know it?
Jeremiah 17:10 I, the Master, search the heart, I try the kidneys and give every man according to his ways, and according to the fruit of his deeds.
Jeremiah 10:23 O Master, I know the way of man is not in himself: It is not for man who walks to direct his own steps.
This describes the carnal man without the begettal of His Spirit.
Romans 8:6-9 (King James Version)
Romans 8:6 For to be carnally minded is death; but to be spiritually minded is life and peace.
Romans 8:7 Because the carnal mind is enmity against Elohim (god): for it is not subject to the law of Elohim (god), neither indeed can be.
Romans 8:8 So then they that are in the flesh cannot please Elohim.
Romans 8:9 But you are not in the flesh, but in the Spirit, if so be that the Spirit of Elohim dwells in you. Now if any man has not the Spirit of Messiah, he is none of His.
