Nothing is needed to explain this video of James White. His self-love and ego are made too obvious for anyone to deny, well, except maybe by him. Egomaniacs always explain themselves by telling us that they are simply so good that they might as well admit it and announce it to the world.

Romans 12:3 For I say, through the grace given unto me, to every man that is among you, not to think of himself more highly than he ought to think; but to think soberly, according as God hath dealt to every man the measure of faith.
