“the law of God”, “a law of faith”, “the law of the Spirit of life”?

"the law of God"(Rom. 7:22, 25) [vs. "the law of sin"(vv. 23, 25)]

"a law of faith"(3:27) [vs. sin that is our master (6:14, 15)],

"the law of the Spirit of life"(8:2) [vs. "the law of sin and death" (v. 2)].

When I was meditating on these three laws that Apostle Paul mentioned in the Book of Romans,

I thought these laws are the Triune God’s law –

the Father God’s law, the Son Jesus’ law of faith and the law of the Holy Spirit.

And I tried to meditate this Triune God’s law in connection with the core theme of the Book of Romans, that is ‘The righteousness of God that is revealed in the gospel,

that is “The righteous will live by faith” (1:17).

I first thought that salvation is the work of the Triune God.

God the Father plans salvation, God the Son completes salvation

and God the Spirit applies to us the saving work planned by the Father God

and completed by the Son Jesus Christ. (Cf. Eph. 1:3-14)

Then, I thought about what are “the law of God,” “a law of faith” and “the law of the Spirit of life”

in connection to the saving work of the Triune God.

Father God’s law is His saving love,

Son Jesus’ law of faith is the truth of salvation that whoever believes in Jesus Christ will be saved,

“the law of the Spirit of life” is the applied law of Father God’s saving love

and the saving truth of the Son Jesus Christ by faith,

that is the power of salvation that makes us to obey the Jesus’ twofold command.
