Paul was referring to his pre-conversion status.For me I'll stand with Paul and with John Newton :
1Ti 1:15
This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief.
He didn't keep persecuting the church after he was converted ftom darkness to light.
You will need to show me that, as I don't agree with it at all.At the age of 82, Newton said, "My memory is nearly gone, but I remember two things: that I am a great sinner — and that Christ is a great Savior!"
As for yourself , you have said you can name no Christian living or dead who thinks what you think.
Here are some verses by the apostles that say what I say...Which comes as no surprise to me by the way
“Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.For he that is dead is freed from sin.” (Rom. 6:6-7)
"Being then made free from sin, ye became the servants of righteousness." (Rom 6:18)
"But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life." (Rom 6:22)
"There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit." (Rom 8:1)
"Awake to righteousness, and sin not; for some have not the knowledge of God: I speak this to your shame." (1 Cor 15:34)
"For he hath made him to be sin for us, who knew no sin; that we might be made the righteousness of God in him." (2 Cor 5:21)
"Finally, brethren, farewell. Be perfect, be of good comfort, be of one mind, live in peace; and the God of love and peace shall be with you." (2 Cor 13:11)
"And you hath he quickened, who were dead in trespasses and sins;
Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others." (Eph 2:1-3)
"Let us therefore, as many as be perfect, be thus minded: and if in anything ye be otherwise minded, God shall reveal even this unto you." (Phil 3:15)
"Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus:" (Col 1:28)
"Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, let everyone that nameth the name of Christ depart from iniquity." (2 Tim 2:19)
"All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
That the man of God may be perfect, thoroughly furnished unto all good works." (2 Tim 3:16-17)
"But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul." (Heb 10:39)
If that isn't enough from the other teachers and adherents of the doctrine which is according to Godliness, I have more.
