Then perhaps you should ask for a raise.
And as has been offered to you several times now, no one knows for certain about other people's salvation because no one knows other people's hearts but God.
But each individual can and should be certain of his own salvation, exactly as Scripture encourages us to believe over and over again.
Because either Christ paid for your sins or He didn't. Either you stand acquitted before God or you don't.
You need to read the Bible more.
These words sound nice, it's a nice courtroom and legal analogy. I've read the formulas, I actually have, but, honestly, I think the theology is just not for some.
It is appealing to have a formula and to fit everything into it. I've seen the same with dispensationalists. At some point, in my opinion again, figuring it all out and fitting it all together, leaves us with something more, something still is lacking. We cannot hold God in our formulas and systems.

Thank you for your kind advice.
