(quote from RealReality.org/Real_Faith_and_Reason_Vol_2_-_Scientia.pdf)

We all have wrong ideas we learned and sincerely believe. Not one of us can say, “God can’t teach me anything.” As we live our lives, wrong ideas plant themselves in our worldviews. Once we allow an idea to plant itself in our worldviews, that idea seems real to us. It seems like part of reality. The wrong ideas we accepted and nurtured in our minds became strongholds of error. We have many inner strongholds that hold us down.

Others could correct us, but our worldviews act as filters. When we hear something outside our worldviews, it seems insane to us. When we say something that’s not in someone else’s worldview, what we say sounds insane to them. This worldview-filter deceives every person to some extent.

Intelligence can’t solve the problem. And education gives us unwarranted confidence in our worldview-filters. Intelligence and education can make the problem worse since they can puff us up in pride. Pride can make us stop seeking God for correction and further revelation. Only our spiritual weapons of warfare can tear down our inner delusions. Our inner delusions are the strongholds we have in our minds.
