You don't have your salvation.
As our Savior plainly stated: “He that endures to the end, the same shall be saved.”
Yeshua discussed what salvation required with Nicodemus in John ch 3. You must be reborn into a specially created body that is a part of the realm of the Father, rather than the present biological body that can exist only in space-time.
Those that endure in the faith to the end will experience this rebirth. Those that do not are discussed in Hebrews ch 6 and 10.
That Faith cometh by hearing the Word of YHVH.
The “word” at the time that Paul penned that admonishment was the Tanakh.
In Acts 15, the gathered apostles in Jerusalem stated that the new believers needed to hear Moses read in their synogogue “every Sabbath day.”
The “inherited lies” of our fathers (Jeremiah 16:19) attempt to deny this fact.
O LORD, my strength, and my fortress, and my refuge in the day of affliction, the Gentiles shall come unto thee from the ends of the earth, and shall say, Surely our fathers have inherited lies, vanity, and things wherein there is no profit.

Jesus own words tell us that it's a done deal.
If you choose to not believe Him, that's on you.
John 5:24 Truly, truly, I say to you, whoever hears my word and believes him who sent me has eternal life. He does not come into judgment, but has passed from death to life.
John 6:37-39 All that the Father gives me will come to me, and whoever comes to me I will never cast out. For I have come down from heaven, not to do my own will but the will of him who sent me. And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day.
John 10:25-30 Jesus answered them, “I told you, and you do not believe. The works that I do in my Father's name bear witness about me, but you do not believe because you are not among my sheep. 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.”
Your Roodian mind is warped! How could you so misconstrue what Jesus explained to Nicodemus in John 3? It’s amazing!!!
