Well, let's see about Paul -

12 For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day.

37 Nay, in all these things we are more than conquerors through him that loved us.
38 For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come,
39 Nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord.

seems to me that Paul was pretty confident of his salvation, y'all. I nderstand that the Catholics misrepresent the Bible and try to convince you that you can't know, but since salvation is by FAITH, and that faith is the SUBSTANCE of your salvation - if you DON'T KNOW whether you're saved - then maybe you aren't saved at all.

I know for sure - have for decades!!
