Notice how he speaks of ungodliness in the past tense ? He’s not saying feel free to keep living that way because of grace of you continue on in those epistles you find instruction that leads to repentance and right living fulfilling the promise of righteousness by faith
“Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry: For which things' sake the wrath of God cometh on the children of disobedience:
In the which ye also walked some time, when ye lived in them.
But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth. Lie not one to another, seeing that ye have put off the old man with his deeds;
And have put on the new man, which is renewed in knowledge ( hearing and believing the gospel of the kingdom )
after the image of him that created him:
Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering; Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye.
And above all these things put on charity, which is the bond of perfectness.
And let the peace of God rule in your hearts, to the which also ye are called in one body; and be ye thankful.
Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord.”
Colossians 3:5-10, 12-16 KJV
the instructions about repenting from our old sinful ways and doing the new things walking in the good works the gospel sets before us is part of it all.
you have made good post here , I think if you let the rest of those epistles into your belief it will change what “ grace and faith “ means into a powerful effectual changing of the sinner into a child of God in deed and truth
