Certainty has been referred to as the indulgence of fools.......is being convinced beyond reason a moral or immoral position?
Na, sounds more like a phrase that those who would shed doubt on what you know by experience. But that really isn’t the question, it’s to shed doubt on your perception on what you understand about (interpretation of) what you’ve experienced.
Adam and Eve had their understanding of what God said to them (they did experience the Presence of the Voice of the Lord) brought to question therefore not certain about their understanding (actually began doubting whether to trust God or not) and went by their own judgement (like gods judging what is good and evil) and died of the life they had in God’s sight. after they sealed their new faith in themselves as judges of good and evil by the act of eating of that fruit. (granted, beguiled by one who has seen God in Heaven)
And yes, stick to what you know by experience, and your witness is true, no matter the subject is moral. The hearer can say or make of it what they will, but your witness is true and the Lord has witnessed that your witness is true.
