God as Creator of life has only two ways of life: a way based on “give” (love) that leads to eternal life and a way based on “get” (selfishness) that leads to death.
Jesus Christ taught:
“It is more blessed to give than to receive” (Acts 20:35).
Choice for Israel
God always gives a choice to whoever He calls. For example, when He called Israel as a nation, He told them:
“Behold, I have set before you today life and good and death and evil” (Deut 30:15).
Since God, as a righteous Judge, gives us free will, God will not “force” anyone to choose life and good. That is up to the person called. But God advices:
“I call Heaven and earth to witness against you today that I have set before you life and death, the blessing and the curse. Therefore, choose life, that you may live, you and your seed” (Deut 30:19).
Choice for Adam and Eve
The same God had given the same choice to Adam and Eve in the form of the Tree of Life and the Tree of the knowledge of Good and Evil (Gen 2:9, 16-17).
God gave the same free will to Adam and Eve and hence didn’t “force” them to choose the right Tree. Neither did God prevent them from selecting the wrong tree. But He advised them in a command not to eat of it.
The Way of Giving, Goodness, Blessing and Life
The same Creator God has clearly shown the only way of Life, Blessing, Goodness and Giving, which is “the narrow gate and constricted road” (Matt 7:14) through His spiritual Law.
God’s entire spiritual Law is contained in one word: “Love” (1 Tim 1:5). This love is two-pronged: love towards God (summarized in 4 commandments) and love towards man (summarized in 6 commandments) and nothing is greater than these commandments (Mar 12:30-31). (No wonder, in the entire Scripture that belongs to God, the only part that is written by God Himself is the Ten Commandments).
In the First Covenant/Testament, God wrote these commandments on stone tablets. In the Second Covenant/Testament, the same God wrote these same commandments in the heart and mind of the believers (Heb 10:16 quoting Jer 31:33).
God’s Law is Spiritual
How does God write these commandments in hearts and minds?
“you are Christ's letter, served by us, not having been inscribed by ink, but by the Spirit of the living God, not in tablets of stone, but in fleshly tablets of the heart” (2 Cor 3:3).
See, Paul contrasts "ink" with "God's Spirit". So, it is clear that it is through the Holy Spirit that the spiritual Law is written in the mind and heart of a new believer.
When God gives His Holy Spirit to a believer, the latter becomes a spiritual person because God has written His spiritual Law in his mind and heart. He is able to follow God’s Law through the Holy Spirit.
The physical (even if they are of Israel) cannot follow the spiritual (Rom 8:7). The First Covenant was a physical contract. Hence, it was a “ministry of death having been engraved in letters in stone” (2 Cor 3:7) that “kills” (verse 6).
The Second Covenant was a spiritual contract. Hence, it is “the ministry of the Spirit in glory” (verse 8) that “makes alive” (verse 6).
Paul’s Usage of Law
When approached in this way, we would be in a better position to understand Paul when he speaks about law.
The ‘law of the mind’, the ‘law of the Spirit of life in Christ Jesus’, the ‘law of faith’, the ‘law of righteousness’, the ‘law of Christ’ are all the same. They all point to the spiritual Law of God.
The law of the mind: these are the same commandments written first on stone and secondly on the mind and heart through the Holy Spirit (Heb 10:16). Paul is not talking about the natural mind of an unconverted man but about the spiritual mind of a believer.
The law of the Spirit of life in Christ Jesus: “the Law is spiritual”, “holy”, “just” and “good” (Rom 7:12,14). The law of Spirit is the same.
The law of faith: “Do we, then, abolish the Law by this faith? Of course not! Instead, we uphold the Law” (Rom 3:31). Those who have faith will uphold and keep the spiritual law.
The law of righteousness: “Do you not know that to whom you present yourselves as slaves for obedience, you are slaves to whom you obey, whether of sin (disobedience of Law) to death, or obedience (obedience of Law) to righteousness?” (Rom 6:16). Sin is opposite of righteousness and both are in relation to God’s spiritual Law. We obey God means we obey God’s commandments.
The law of Christ: the law of Christ is interchangeable with the law of God just as the church of God is interchangeable with the church of Christ, so these are the same. “not being without Law of God, but under the law of Christ” (1 Cor 9:21).
So all of these are to be understood as actual laws, the spiritual laws contained in the Ten Commandments. And whatever opposes these are to be understood as the law of sin, flesh and death.
