The Foundational Error
A single foundational error is at the root of ungodly thinking. And since there’s only one true Foundation, Jesus Christ, building on any other foundation is a foundational error. While the worldview of naturalism forces this error, people also find other ways to make the same error. They find ways to refuse to acknowledge the reality of God. For example, materialism, agnosticism, and atheism are common ways of making this foundational error in thinking. Secularism is another word for the same sort of godless thinking. Another word is rationalism. There’s nothing rational about rationalism. And we, as Christians, make this error whenever we fail to acknowledge Christ in all our ways.
Reasoning without God is the foundational error in thinking because, without God, we have no way to generate precise and correct knowledge of truth about anything. We know unanointed human reasoning has no power to think rationally since, without God, we interpret observations using axiomatic-thinking fallacies. That means we interpret observations by making up stuff and making believe the made-up stuff was true. That’s the ungodly-thinking fallacy, and we can’t get around the ungodly-thinking fallacy without revelation. Ungodly thinking always depends on pretending and faking it, but those of us who love truth and aren’t afraid of reality need the one Way to know truth. Thankfully, this Way is available in the One Who is Truth. He is the Way, and He’s the only Way. Everyone who loves truth finds Jesus.
