Nope.
Paul NEVER taught about "works of grace".
He always CONTRASTED "works" and "grace":
So--connecting obedience with His grace--isn't works of grace?
Romans 2:5-11---King James Version
5 But after thy hardness and impenitent heart treasurest up unto thyself wrath against the day of wrath and revelation of the righteous judgment of God;
6 Who will render to every man according to his deeds:
7
To them who by patient continuance in well doing seek for glory and honour and immortality, eternal life:
8 But unto them that are contentious, and do not obey the truth, but obey unrighteousness, indignation and wrath,
9 Tribulation and anguish, upon every soul of man that doeth evil, of the Jew first, and also of the Gentile;
10 But glory, honour, and peace, to every man that worketh good, to the Jew first, and also to the Gentile:
11 For there is no respect of persons with God.
And wasn't there another kind of works--which had the opposite effect?
Galatians 5:19-21---King James Version
19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
21 Envyings, murders, drunkenness, revellings,
and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Then--there was Paul's favorite--the works of the law

1 Corinthians 7:19--King James Version
19 Circumcision is nothing, and uncircumcision is nothing, but the keeping of the commandments of God.
