If you know of even one verse that gives one infallible knowledge *now* that one is elect for glory, I would like to see it. If you don't know that your "elected" *now* these verses are utterly stupid...
Col 3:12-15 Therefore, as the elect of God, holy and beloved, put on tender feelings of mercy, kindness, humbleness of mind, meekness, long-suffering, forbearing one another and forgiving yourselves, if anyone has a complaint against any. As Christ forgave you, so also you do. And above all these things put on love, which is the bond of perfectness. And let the peace of God rule in your hearts, to which you also are called in one body, and be thankful.
If you don't know that you are the elect *now* then how can you do any of this?
First, how do you know that the word "elect" in Col 3:12 is referring to "election to glory" and not merely "election to grace"? Without knowing *that*, this verse would not show you that you are elect for glory.
Second, how do you know that no apostates-to-be ever read this verse and interpret it to mean that they are elect for glory? If apostates-to-be can read this verse and interpret it that way, then just because you interpret it as meaning that you are elect for glory does not show infallibly that you are elect for glory. You could still turn out to be one of those apostates-to-be who mistakenly think the verse is referring to them.
