“For if, having escaped the world’s impurity through the knowledge of the Lord and Savior Jesus Christ, they are again entangled in these things and defeated, the last state is worse for them than the first. For it would have been better for them not to have known the way of righteousness than, after knowing it, to turn back from the holy command delivered to them.”
— 2 Peter 2:20–21 (CSB)

Peter gives a serious warning about people who encounter the truth of Christ but later turn away and become entangled again in the corruption of the world. In the larger context, he is especially addressing false teachers whose lives and teachings reveal that they have rejected the truth they once knew. Greater knowledge brings greater responsibility, making deliberate rejection of God’s truth especially dangerous. This passage calls us to remain firmly rooted in Christ, allowing the truth we know to continually shape the way we believe and live.
