God engraved the Ten Commandments in stone. The stone speaks of:
* Something permanent, unchanging. Timeless. Won’t decay, or be blown away by the winds of change.
* Stone, however, can be easily broken if cast down.
* Impossible to edit or alter the text without destroying it.
* Only the moral law was written in stone, not the ritualistic law.
* The heart of unregenerate man is likened to a stone:
“A new heart also will I give you, and a new spirit will I put within you: and I will take away the stony heart out of your flesh, and I will give you an heart of flesh.
And I will put my spirit within you, and cause you to walk in my statutes, and ye shall keep my judgments, and do them.” (Ezekiel 36:26-27)
“But this shall be the covenant that I will make with the house of Israel; After those days, saith the Lord, I will put my law in their inward parts, and write it in their hearts; and will be their God, and they shall be my people.” (Jeremiah 31:33)
God first wrote His moral law in stone as the schoolmaster to bring us to Christ (Gal. 3:24-25) then whoever believes on Christ gets a new heart, with the moral law engraved deep within.
You are no longer UNDER the law when the law is written in your heart. There’s a change of position, from under, if it is above you, to within you. If we did not have a new heart we would still be under the law. You then fulfill the moral law if both the Holy Spirit and the moral law is in your heart, and you can never separate the two.
“Do we then make void the law through faith? God forbid: yea, we establish the law.” (Romans 3:31)
The heart of stone, under the law, could never fulfill the law.
The new heart of flesh, the new creation in Christ, by the Spirit can only fulfill the moral law, and does.
And this new creation, this new heart of flesh has the moral law written inside.
Therefore, those who have a problem with, or want to change any moral command of the New Covenant reveal that perhaps these commands are not written in their hearts.
Also consider:
“Now therefore why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?” (Acts 15:10)
This refers to the problem of trying to force the Jewish law upon Gentiles. The ritualistic law is described as an unbearable burden.
So, we have two streams of error: people either return under the ritualistic law, or they think they are justified bcos they think they keep the moral law, OR, they are false believers who don’t have the true Holy Spirit, or true conversion, and the moral law is not written in their hearts, so they don’t love the truth, and their morality becomes pragmatic, circumstantial or opportunistic: as it suits them.
God’s own morals
When it comes to the moral law we need to acknowledge they are God’s own morals.
It’s not some arbitrary, shifting human morality, it’s God’s own morals, reflecting the heart of God: what He likes, what He hates. You don’t lie bcos God hates lying, it goes against everything that He is, and so forth. Whatever morality is spelled out in the New Covenant, that is the morality acceptable to God, for it is God’s morality, and anything contrary to His nature He hates.
The New Covenant being written in our hearts means our heart agrees with the heart of God: we love what He loves, and hate what He hates, from the bottom of our heart.
