No, you are assuming I am assuming Paul was correct.
The alternative is that Paul was sinning by bearing false witness and YOU then still have the same problem: one of the apostles sinned after hs regeneration.
Then Paul and Peter were not saved and nether are you.
There is a more scripturally consistent alternative.
Romans 8:26-39
In the same way the Spirit also helps our weakness; for we do not know how to pray as we should, but the Spirit Himself intercedes for us with groanings too deep for words; and He who searches the hearts knows what the mind of the Spirit is, because He intercedes for the saints according to the will of God. And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose. For those whom He foreknew, He also predestined to become conformed to the image of His Son, so that He would be the firstborn among many brethren; and these whom He predestined, He also called; and these whom He called, He also justified; and these whom He justified, He also glorified. What then shall we say to these things? If God is for us, who is against us? He who did not spare His own Son, but delivered Him over for us all, how will He not also with Him freely give us all things? Who will bring a charge against God's elect? God is the one who justifies; who is the one who condemns? Christ Jesus is He who died, yes, rather who was raised, who is at the right hand of God, who also intercedes for us...... I am convinced that neither death, nor life, nor angels, nor principalities, nor things present, nor things to come, nor powers, nor height, nor depth, nor any other created thing, will be able to separate us from the love of God, which is in Christ Jesus our Lord.
NOTHING can separate you from the love of God found in His Son if you have been covered in the Son's shed blood. Nothing. Not even your own post-regeneration sins.
Otherwise, you, Unknown Soldier, render impotent the work of the supposedly almighty God. You make your post-regeneration sin more mighty than God. So consider what David and I have posted and stop treating us like we're your adversaries.
2 Peter 1:1-9
Simon Peter, a bond-servant and apostle of Jesus Christ, To those who have received a faith of the same kind as ours, by the righteousness of our God and Savior, Jesus Christ: Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord; seeing that His divine power has granted to us everything pertaining to life and godliness, through the true knowledge of Him who called us by His own glory and excellence. For by these He has granted to us His precious and magnificent promises, so that by them you may become partakers of the divine nature, having escaped the corruption that is in the world by lust. Now for this very reason also, applying all diligence, in your faith supply moral excellence, and in your moral excellence, knowledge, and in your knowledge, self-control, and in your self-control, perseverance, and in your perseverance, godliness, and in your godliness, brotherly kindness, and in your brotherly kindness, love. For if these qualities are yours and are increasing, they render you neither useless nor unfruitful in the true knowledge of our Lord Jesus Christ. For he who lacks these qualities is blind or short-sighted, having forgotten his purification from his former sins.
Note that text plainly states, "former sins." It does not say, "current sins," or "future sins." You and I were cleansed from past sins, and grace-given, Spirit-driven confession, repentance, amends, forgiveness, and ongoing reconciliation keep us that way. Flesh-driven alternatives merit nothing salvifically.
James 5:13-16
Is anyone among you suffering? Then he must pray. Is anyone cheerful? He is to sing praises. Is anyone among you sick? Then he must call for the elders of the church and they are to pray over him, anointing him with oil in the name of the Lord; and the prayer offered in faith will restore the one who is sick, and the Lord will raise him up, and if he has committed sins, they will be forgiven him. Therefore, confess your sins to one another, and pray for one another so that you may be healed. The effective prayer of a righteous man can accomplish much.
If any among the body of Christ have sinned.... those sins will be forgiven. Therefore, those in the body of Christ - those who are already redeemed, regenerate and indwelt are to confess their sins to one another. There would be no need for confession and repentance if we never sinned after regeneration.
Regeneration would be weak if another sin could eradicate its effect. God's work would be fruitless if another sin were all it takes to prevent Him from saving the sinner after regeneration and indwelling.
