There are no willful practicing impenitent saved sinners, since that is contrary to to saving faith. Faith is what appropriates justification, without works, but that faith which Scripture refers to as salvific is that out of a poor and contrite heart, (Ps. 34:18; Is. 66:2) and which effects characteristic obedience to the Object of said faith, to please Him, (1 John 3:3-10; Romans 6:20-22) the risen Lord Jesus, who loves righteousness and hates iniquity, thus evidencing
"things which accompany salvation." (Heb. 6:9)
Works themselves do not save, but they do evidence what we believe, and thus whether one is a believer. Knowing, brethren beloved, your election of God...And ye became followers of us, and of the Lord, having received the word in much affliction, with joy of the Holy Ghost: (1 Thessalonians 1:4,6)
All that we choose to do is a result of what we truly believe, at least at the moment, thus faith and works are inseparable - though it is the faith behind works that is counted for righteousness - and one simply cannot claim to believe on the Lord Jesus Christ for salvation - and this faith is in a person, not just in a promise abstract from who and what He is - and then willfully impenitently live contrary to His known will.
For which obedience includes repentance when convicted of not walking in obedience. . (2 Corinthians 7:9-11; cf. James 4:17) It is only these who are promised salvation, such as in, " My sheep hear my voice, and I know them, and they follow me: And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand." (John 10:27-28)
In contrast to such texts which warn, "For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries. (Hebrews 10:26-27)
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. (Galatians 5:21)
For ye have need of patience, that, after ye have done the will of God, ye might receive the promise. For yet a little while, and he that shall come will come, and will not tarry. Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him. But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul. (Hebrews 10:36-39)
But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel. (1 Timothy 5:8)
Thus we have warnings such as
Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates? (2 Corinthians 13:5)
In contrast to,
But, beloved, we are persuaded better things of you, and things that accompany salvation, though we thus speak. For God is not unrighteous to forget your work and labour of love, which ye have shewed toward his name, in that ye have ministered to the saints, and do minister. (Hebrews 6:9-10)
AMEN!!
