I am sorry to hear about your Dad.do you think he lost his salvation?
now dont go saying that he never had it in the first place - i've said this before and will say it again - if you accept Christ, it means you've accepted him. if you've rejected Christ - it doesn't mean that you never accepted him in the first place - it means you have rejected him.
You ask a question and work to cancell out an argument that you do not care for? How silly.
You cannot make the case that it is not true that he was never saved.
Joh 10:4
And when he putteth forth his own sheep, he goeth before them, and the sheep follow him: for they know his voice
Joh 10:5
And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.
Joh 10:27
My sheep hear my voice, and I know them, and they follow me:
Joh 10:28
And I give unto them eternal life; and they shall never perish, neither shall any man pluck them out of my hand.
Joh 10:29
My Father, which gave them me, is greater than all; and no man is able to pluck them out of my Father's hand.
Those who are truly saved will never leave the faith.
