The title of the thread says "If you believe you can lose your salvation, you are not saved". As I pointed out, Paul knew he could become a reprobate 1 Cor 9:27 so the thread title is not true according to Paul nor did Paul teach OSAS.
1 Cor 9:27 - but I discipline my body and make it my slave, so that, after I have preached to others, I myself will not be disqualified (adokimos).
adokimos
1) not standing the test, not approved
1a) properly used of metals and coins
2) that which does not prove itself such as it ought
2a) unfit for, unproved, spurious, reprobate
Interesting that you go to the least meant word there, for lexicons list the semantic range of meanings from most common usage to least. In fact, Paul was saying that he disciplined himself so that he wouldn't be disapproved, which is a far cry from any thought of losing salvation.
God promise to CONDITIONALLY save them that obey, Heb 5:9 and those that quit obeying therefore lose God's promise of salvation.
Heb 5:9 - And having been made perfect, He became to all those who obey Him the source of eternal salvation
It should be clear about who will obey Him; that would be believers only. Why would anyone think that any unbeliever would obey Him? So this verse says nothing about HOW one will be saved, or on what basis. It's just a statement about the fact that He is the source of salvation. And it is obvious that only believers will obey Him.
But, obedience isn't the basis for salvation. Believing in Him is, as the abundance of Scripture testifies:
Mark 16:16 " He who has believed and has been baptized shall be saved; but he who has disbelieved shall be condemned
Luke 8:12 "Those beside the road are those who have heard; then the devil comes and takes away the word from their heart, so that they will not believe and be saved.
Acts 4:12 "And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved."
Acts 11:14 and he will speak words to you by which you will be saved, you and all your household.'
Acts 16:31 They said, “Believe in the Lord Jesus, and you will be saved, you and your household."
Rom 10:9, 10
9 that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved; 10 for with the heart a person believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.
Rom 1:16 For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek.
Eph 2:8 For by grace you have been saved through faith; and that not of yourselves, it is the gift of God;
2 Tim 3:15 and that from childhood you have known the sacred writings which are able to give you the wisdom that leads to salvation through faith which is in Christ Jesus.
1 Peter 1:5 who are protected by the power of God through faith for a salvation ready to be revealed in the last time.
1 Peter 1:9 obtaining as the outcome of your faith the salvation of your souls.
2 Thess 2:13 But we should always give thanks to God for you, brethren beloved by the Lord, because God has chosen you from the beginning for salvation through sanctification by the Spirit and faith in the truth.
I can provide a list of 9 verses that base the receiving of eternal life on believing in Christ as well.
And none of the 21 verses mention obedience as a condition.
In Rom 11:29 God had promised salvation to the Jews through their conditional faith in Christ, yet most rejected Christ. Even though the majority of Jews rejected Christ, God did not "revoke" or repent of that promise but instead left that door of the promise of salvation ajar for the Jews.
The error here is in the assumption that an offer of salvation to the Jews is the "gift" noted in Rom 11:29. It is NOT, for Paul never defined any offer as a gift in Romans. In fact, he did define "God's gifts" as justification in 3:24 and 5:15,16,17 and eternal life in 6:23. It is these gifts of God that are irrevocable.
God nowhere ever promised unconditional salvation to the Jews whereby they could never lose it under any circumstance.
Is there any Biblical teaching to support this claim? No, there is not.
It is important to note what Jesus did NOT say in Jn 6:40 above...Jesus did NOT say "... that every one which seeth the Son, and believeth ONLY on him,....." Christ NEVER taught belief only saves but also taught one must repent, Lk 13:3; confess, Matt 10:32,33 and be baptized, Mk 16:16 to be saved. Therefore a NT belief INCLUDES repentance confession and baptism.
I've given 12 verses that refutes your claim, and there are 9 more about eternal life based on faith apart from anything else.
Jesus did not contradict Himself by saying one one hand believing only saves but then saying one must also repent confess and be baptized to be saved.
imho, this would take hours of teaching to clear out all the error in your claims, but suffice it to say, repentance in the Greek means to "change the mind", which is absolutely necessary in order to believe in Christ. So there is no contradiction between repentance and belief. And Mark 16:16 is a disputed text, as it doesn't exist in the earliest manuscripts, but only in later ones, which indicates from v.9 on was added by a scribe. As far as the confessing of Rom 10:10, that has to do with faithful obedience of a witness and ambassador for Christ, and will result in salvation in the sense of being delivered from temporal trials. But I know this will most likely be rejected.
Matt 7:21, the context says "Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven."
Those that DOETH the will of the Father are the ones that enter the kingdom.
I've already explained that.
Nowhere did Jesus say belief only saves.
Let's be clear about this. Jesus NEVER said that one must work to be saved. When He spoke of salvation or eternal life, it was on the basis of faith in Him APART FROM ANY OTHER CONDITIONS.
Again, Jesus did not contradict Himself by saying one one hand believing only saves but then saying one must also repent confess and be baptized to be saved.
Has been explained.
Is the bible or Greek lexicons the repository of God's truth?
This is an irrelevant question. The ONLY WAY to understand the original language of the NT is to consult the Greek lexicons.
You left out the word "DOETH" from Mt 7:21..... those that DOETH the will of the Father are the ones that enter the kingdom.
I didn't leave anything out. Doing the will of the Father is quite simple: believing in Jesus Christ as Savior.
