Everyone is a Dogmatist
Everyone is dogmatic about their foundational beliefs- so both the Christian and non-Christian must bear the burden of “showing” their dogma to be true. And as Clark said- to deny that you’re dogmatic is self-refuting because you do it dogmatically!
As a result, once the Christian and non-Christian bring their dogma to be examined or test driven- only God’s Word will remain. Everything else is but chaff blown by the wind- a sandy foundation destined to perish!
Matthew 7:26-27, “26 But everyone who hears these words of mine and does not put them into practice is like a foolish man who built his house on sand. 27 The rain came down, the streams rose, and the winds blew and beat against that house, and it fell with a great crash.”
