Second Corinthians 13

Verse 5 - Examine yourselves in the mirror of God's words, compare God's words with your current morality, lifestyle and world-view to see whether you are in "THE FAITH"; prove your own selves, your lives, your "walk", your conduct, your religious beliefs, your spiritual practices, prove them all against the Word of God.

Do you not have assurance you are genuinely authentic possessors of salvation, assurance Christ Jesus is alive inside you through the indwelling of the Holy Spirit and through God's Word being inside your minds... unless you actually are false professers of salvation, reprobates, fakers, posers, frauds, and NOT genuinely authentic Christians at all?
