Scripture reveals God/Jesus has a list. A list of the saved (real Christians). ("rather rejoice that you name is written in heaven")
No human on earth has access to that list. (feel free to cite name of anyone you think has access to that list.)
So our human beliefs of who is on the list of saved and who isn't really doesn't matter.
That being said, when I hear someone say such as "Jesus is fraud" then I am confident they are not (at least yet) on the list of saved.
When I hear someone say "Jesus is Lord", I am confident they are on the list. Can I be fooled ? Maybe so ... but Jesus can't be fooled.
And I pity anyone who pretends to be a Christian and really isn't. I need not fear about it.
Christianity does not hold a monopoly on salvation; there is no list of who is saved;
in 1Tim. 2:3-4 God desires that ALL humans be saved;
in Isaiah 45:23 God swears to himself that he will save ALL of humanity.
This tendency of many believers to place people in hell is insane.
Christ Himself has been given the monopoly on salvation. Jesus alone was sent by God to be alone on the cross for our sins.
Certainly it is the will of God that all be saved ... sadly, many will thwart-frustrate the the will of God and end up lost.
To all: If you come to believe God is going to save EVERYONE ...you will end up very disappointed.
I could cite a lot of scripture showing that many will not be saved ... but most all are already aware of it.
If you don't believe it .... well, so be it. Have a nice day, JP
