Yes, God does not lie, and you have not explained why you think the 16 Scriptures are lies or do not mean what they say.
Please never use "lose"; the truth being discussed is "repudiate".
It is good to believe God, and He says the 16 Scriptures.
BTW, I understand your goad (ACTS 26:14), because I was raised to believe OSAS.
Because if they were truly RESCUED or SAVED (in this case. the one who was dead in trespasses and sins, having been made alive (rescued or saved) in Christ not because they earned it, but because Christ paid the way of salvation
then you could never be made dead again in trespasses and sin. The fact would be if in the end you end up dead (condemned0 you were never saved to begin with.
I agree. If a person accepts they can lose all that occurred at their rebirth in Christ, I think it is a tragedy.
Because they are living a tenuous existence. The idea that God can save us but we can overcome his power and authority by human choice. And as such choose to damn ourselves to return to all that we formerly were as one dead in our sins.
And what if we later choose to follow Christ again?
Hebrews 6
For it is impossible, in the case of those who have once been enlightened, who have tasted the heavenly gift, and have shared in the Holy Spirit, 5 and have tasted the goodness of the word of God and the powers of the age to come, 6 and then have fallen away, to restore them again to repentance, since they are crucifying once again the Son of God to their own harm and holding him up to contempt.
That's because Jesus gave us this.
John 10
"My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father's hand. I and the Father are one.” "
That's the truth and promise of The Word.
Why would we insist God needs our assistance for God to keep his word to us?
