Just find one that teaches why you can't lose your salvation, basing this truth on the fact that you can't stop being born again, and stressing that the blood of Jesus that made you right with God, always does.
Find that teacher-preacher-pastor, and you are home.
And by using that theology of truth, you find out who the deceivers are, and you can avoid them.
They might be somewhere but not in biblical truth if they’re taught OSAS:
Paul warns the church at Corinth to make sure they aren’t reprobates.
2Co 13:5 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?
He warns that some of the church that think they’re in the faith can actually have become reprobates.
The word reprobates is ADOKIMOS in the Greek, which becomes important in the verse where Paul himself says he has to subjugate his flesh (the flesh is worldly desires to sin) daily, lest after preaching salvation to others, he end up a castaway.
1Co 9:27 But I keep under my body, and bring itinto subjection: lest that by any means, when I have preached to others, I myself should be a CASTAWAY.
The word castaway is ADOKIMOS in the Greek - reprobate - rejected by God as one who failed the test.
Paul said he would end up a reprobate if he didn’t subjugate his flesh with its sinful desires, daily.
Paul never taught unconditional eternal security - in fact he taught the opposite.
Paul makes clear that AFTERwe have been saved, there is a continuing conflict between our wanting to walk in the flesh, (that wants us to live in sin)- and our desire to walk after the Holy Spirit that now dwells in us - and Paul warns that choosing to live in sins (works of the flesh), will keep us out of heaven:
Gal 5:16 ThisI say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
Gal 5:17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
Gal 5:18 But IF ye be led of the Spirit, ye are not under the law.
Gal 5:19 Now the WORKS OF THE FLESH are manifest, which are these;Adultery, fornication, uncleanness, lasciviousness,
Gal 5:20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
Gal 5:21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell YOU again, as I have also told youin time past, that they which DO such things shall NOT inherit the kingdom of God.
Paul warns us over and over, that if we believers choose to walk after the flesh, we will die spiritually - but if we choose to walk after the spirit, we will have everlasting life:
Rom 8:5 For they that are after the flesh do mind the things of the flesh; but they that are after the Spirit the things of the Spirit.
Rom 8:6 For to be carnally minded isDEATH, but to be spiritually minded isLIFE and peace.
Rom 8:7 Because the carnal mind isENMITY against God: for it is not subject to the law of God, neither indeed can be.
Rom 8:8 So then they that are in the flesh cannot please God.
Verse 8:7 Paul warns above, that having a carnal mind is ENMITY against God, meaning you actually become Gods ENEMY.
Will God let His enemies into heaven?
Jas 4:4 Ye adulterers and adulteresses, know ye not that the friendship of the world is ENMITY with God? whosoever therefore will be a FRIEND OF THE WORLD is the ENEMY of God.
The verse above says sexual sins and being worldly, makes you Gods ENEMY.
Will God welcome His enemies into heaven?
Scripture clearly shows that continuing to remain in Christ is conditional on us 1) continuing to walk in the light, as He is in the light, and 2) continuing to walk after the spirit, instead of after the flesh.
In the two verses below, I include the conditional part of these scriptures that are always left out by hyper-grace, OSAS teachers.
1Jn 1:7 But IF we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.
The word IF makes it a conditional statement.
The blood of Jesus cleansing the believer is conditional on their choosing to continue to walk in the light, as He is in the light.
Next:
Rom 8:1 There is therefore now no condemnation to them which are in Christ Jesus, who walk NOT AFTER THE FLESH, , but after the Spirit.
Having no condemnation, and remaining in Christ, is conditional upon continuing to walk after the Spirit, and not after the flesh.
Unconditional eternal security is not in the scriptures.
