Why is it dangerous to trust in false teachers?

In the sermon, it is pointed out that false teachers are akin to the wizards and necromancers in Isaiah's time, leading people to seek understanding from dead things rather than the living God. As Paul warns in 2 Peter 2, false teachers bring in destructive heresies, turning believers away from the truth of the Gospel. Romans 8:6 states that to be carnally minded is death, emphasizing that relying on human wisdom or works leads to spiritual death. True teachers will point us to Christ, our only hope, while false ones encourage a reliance on the flesh and self-righteousness, which ultimately fails.
