Give us an example because It sounds like you are saying that willful Irreverence means something, even If that person has not been reborn.My life is full of willful irrelevance
If the person has been reborn then they will be seeking to purify their bodies/minds to match the new creation they have become.GOD has equipped them providing sustenance to them and they will display spiritual fruit.
Glory to GOD.
So then a person can act Irreverent to GOD for men to see and still not be true on the Inside
GOD looks at the heart,man looks at outward appearances.
