If you disobey this command you are already failing the test….if you examine yourself in your own estimation and not by the word of God in context and application, you are already failing the test….see a theme here? It is the truth of the word of God, as opposed to your own estimations of yourself, gauged only by your feelings about how you are. Dare you be so arrogant, haughty and deceived as to put your own feelings and thoughts over GOD’S truth??  You have already failed the test…~AGM†

Examine yourselves, to see whether you are in the faith. Test yourselves. Or do you not realize this about yourselves, that Jesus Christ is in you?—unless indeed you fail to meet the test! I hope you will find out that we have not failed the test.
~ 2 Corinthians 13:5-6 ESV
