How do we know that false religion leads to deceit?

The nature of false religion is that it starts with man’s initiative rather than God's sovereign work. Those who kindle their own fires cultivate a religion that conforms to their desires, often resulting in a deep-seated delusion. Scripture warns that the judgments of God leave these individuals in a state of judicial blindness, where they proudly embrace a false confidence and self-righteousness, believing they are secure in their fate without the true intervention of the Holy Spirit. This manifests in a lifestyle marked by empty rituals and ignorance of true spiritual needs, aligning with Isaiah 66:4 which states that God chooses delusions for those who walk in falsehood. Thus, true discernment reveals the deceitfulness embedded in practices devoid of divine authenticity.
