Confusion, causing confusion is a tactic in battle.

Those in sin – light, knowledge, and truth are viewed and received as weapons of war against their opinions, agenda, preferences, desires, and attitudes.

When the truth is encountered, people can in fact be confused. The cause for the confusion is not from God, but it is rooted in the fact of what they believe is in contradiction to what the truth says and so they are confused.

God is not the author of confusion, the mindset, worldview, values, and ideas that truth exposes, there will be an internal struggle to choose what someone will do when the truth comes to them.

When they encounter truth, light, and knowledge, a side is chosen by them.

What will they do when the light of God’s truth enters their world. Their minds are darkened and they are children of disobedience.

Will they come into the light and embrace the love of God, or will they continue in the mentality of sin and disobedience?

Truth is liberating for those sincere.
Truth is offensive to those who choose to stay in sin, darkness, and by default anti-christ.

John 3
19 This is the judgment [that is, the cause for indictment, the test by which people are judged, the basis for the sentence]: the Light has come into the world, and people loved the [c]darkness rather than the Light, for their deeds were evil. 20 For every wrongdoer hates the Light, and does not come to the Light [but shrinks from it] for fear that his [sinful, worthless] activities will be exposed and condemned. 21 But whoever practices truth [and does what is right—morally, ethically, spiritually] comes to the Light, so that his works may be plainly shown to be what they are—accomplished in God [divinely prompted, done with God’s help, in dependence on Him].”
