It is the Spirit who gives life; the flesh profits nothing.
When Martin Luther was debating whether fallen man is utterly dependent upon the Holy Spirit for regeneration, he cited this text and added:
“The flesh profits nothing. And that ‘nothing’ is not a little something.”This is true in two senses:
(1) The flesh does not profit anything.
(2) This point is not merely a nuanced musing.
The flesh cannot profit anything.
This is of no small import.
This is, in fact, paramount in defining from where justification originates.The quick answer::not from you!
