While I must believe what is best warranted, and thus have an open mind on this issue, you have no compulsion over calling a teaching false which has clear substantiation. Rather than facing the issue objectively, you keep resorting to superficial exegesis in avoidance of texts that stand in your way.
It is certain that Judas was damned, but the issue is whether he was ever saved. However, the Galatians were born again, set free, and in grace, but were warned of going into Judaism, resulting in Christ becoming of no effect, of profiting them nothing, as they fell from grace.
Likewise the subject of Hebrews 10 were Christians, but were warned of willfully forsaking the faith, of drawing back into perdition, rather than being of them “who believe to the saving of the soul.” (Heb. 10:19-39)
To relegate these to being unregenerate souls is not an honest analysis of the texts. However, the only way to believe to the saving of the soul is to believe, to rely on in Christ as one’s Lord and Savior, and thus one’s life will be characterized by obedience to Him. Our work is to abide, and He will perfect that which concerns us as we do. But this faith will be tested, and Christians are exhorted to continue and warned of the consequences of departing from the faith.
I have not addressed these verses due to time previous time restraints - I’m a busy man. I do not question your faith or the fact that you have been born again. Most folks who are diligently searching the Scriptures are born again.
Galatians 4:9-11 Paul is addressing those who were being seduced by the Judaizers to move back in the rituals and ceremonies of the law and find themselves in bondage to that law again. To do so would not negate their salvation, but rob them of the abundant freedom they had received in Christ - freedom from the law.
Galatians 5:12 Paul again addressing the same issue, as Christians we are free from the law which brings death.
Hebrews 10:26,27 Verse 26 is defining apostasy. An apostate has seen and heard the truth, he knows the truth, but has wilfully rejected it. This does not mean he has received Christ and then rejected. He came to the knowledge and rejected the truth. The apostate is now hopeless, beyond salvation because he has rejected the only truth that can save him. The lost man who has not been presented the truth, can still be saved by accepting Christ. Apostasy is closely related to the unpardonable sin that the Pharisees were guilty of. They knew the truth, stood in His presence and wilfully rejected Him - even accused Him of being Satanic.
Romans 11:22 Same thing applies to being “cut-off” as to above Scriptures. Not everyone sitting in church is saved, even some who believe they are. People who hear the truth on a regular basis and turn from it are simply not genuine. Those who are not genuine do not persevere and are eventually cut-off from opportunity because they have rejected the kindness of God.
I apologize if I was misunderstood and came on a little strong toward you. This is an issue dear to my heart because I once sat where you do now with regard to this issue and went through real battle in pursuing the truth of this issue. It’s fearful thing to live on a daily basis wandering if I might lose my salvation. I was attending Jimmy Swaggart Bible College when he fell and went on to graduate from Southeastern Univeristy (Assmbly of God). Today I pastor a Southern Baptist Church in Tampa. I know many Pentecostals who are born-again and love God, yet they espouse this doctrine of losing one’s salvation. I understand the battle within and without on this matter. God bless you and I pray you will come to light on the subject. Pray, study the Scriptures and ask God to do whatever is necessary to help you see clear on it. He will!
