Victor, you say:

Yet Scripture tells us :

[color=darkred:3g304xc7][quote:3g304xc7]2 Cor 5:17 – Therefore if any man is in Christ, {he is} a new creature; the old things passed away; behold, new things have come. [/quote:3g304xc7][/color:3g304xc7]

and

John 10:28 – [color=darkred:3g304xc7][quote:3g304xc7]And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.[/quote:3g304xc7][/color:3g304xc7]

I see no “Back and forth” “saved and then unsaved” in Scripture although there are those who walk with a foot in each world – they’re either saved and are guilty of acting as an unbeliever or as it says in 1 John 2:19 -[color=darkred:3g304xc7][quote:3g304xc7] They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us. [/quote:3g304xc7][/color:3g304xc7]

So a saved person doesn’t get unsaved, although as Paul wrote in Romans 7:15 to 8:1 that a saved person stll occasionally commits a sin, he still remains saved. So what are you trying to say Victor?
