you are trying to secure your salvation with words like un born ,,,take back and temporary life....but that does not alter the fact that eternal life is in Christ...and one must remain in obedience to Him ...
Hebrews 5:9
And being made perfect, he became the author of eternal salvation unto all them that obey him;
Christ does not take back eternal life....if a believer fall away from Christ then they are not one with Christ and therefore cannot have eternal life...it is the same principle ..if a man hate his brother he is a murderer and no murderer have eternal life abiding in them...

Does Romans 10:9,10 say that one is saved when they confess Jesus as Lord and believe God raised him from the dead? Does Ephesians say: For by grace are you saved through faith, and that not of yourselves, it is the gift of God? That is how I am saved - through faith by God's grace.
Now I am born again of Spirit - notice BORN AGAIN . . . God had a purpose in using that specific language "born again" relating it to birth. You can't undo birth! THAT IS SALVATION.
Now I begin my walk - that is where my obedience comes in - I WANT to walk in the Spirit and NOT fulfill the lust of the flesh - that is my walk of obedience. When I walk in the Spirit - I am in fellowship and walk in light, i.e. in obedience but when if I fail at times - I fulfill the lust of the flesh and I walk in darkness . . . To restore that fellowship I admit that I have fallen short and I am restored.
BTW - I don't hate my brother even in disagreement . . .
