What does the Bible say about those who try to deceive us?

The Bible speaks about false teachers and deceivers in several passages, specifically in 1 John 2:26-27, where the Apostle John writes to address the issue of those who aim to mislead believers. John reassures the faithful that they possess the anointing from the Holy Spirit, which enables them to discern truth from falsehood. This anointing teaches believers all things and helps them to remain in Christ, as long as they continue to trust in His Word and teachings, rather than the deceptive words of others. It cautions us to be vigilant about the lies that can come from our own hearts, the devil, and false prophets, reminding us that our confidence must be in the truth of God’s Word as our ultimate guide.
