How do we know the doctrine of Antichrist is true?

The truth of the doctrine regarding Antichrist can be firmly established through the teachings of Scripture. Key passages such as 1 John 2:18 emphasize the reality that many Antichrists have arisen, alerting believers to be vigilant against false teachings. Jesus’ words in Matthew 24:24 serve as a direct warning about the seductive power of this deception, illustrating that the Antichrist can have a profound impact on followers of Christ if they are not anchored in the truth.

Additionally, 2 Thessalonians 2:3-12 elaborates on how the delusion will unfold in the last days due to a broad rejection of truth. It is crucial to recognize that any theological position or doctrine that diminishes God's character or attributes any aspect of salvation to human efforts aligns with this warning and can be viewed as part of the Antichrist system. This understanding reinforces the definition of Antichrist as a intellectual and spiritual challenge to the truths of the gospel, rooted in a misrepresentation of God's grace.
