G4560–σάρκινος–sarkinos

For we are conscious that the law is of the spirit; but I am of the flesh, given into the power of sin.

σάρκινός sarkinos “fleshly”

And the teaching I gave you, my brothers, was such as I was able to give, not to those who have the Spirit, but to those who are still in the flesh, even to children in Christ.

σαρκίνοις, sarkinois “to fleshly,”

For you are clearly a letter of Christ, the fruit of our work, recorded not with ink, but with the Spirit of the living God; not in stone, but in hearts of flesh.

σαρκίναις. sarkinais “human.”

That is to say, not made by a law based on the flesh, but by the power of a life without end:

σαρκίνης sarkinēs “fleshly”
