“Who is a liar but he who denies that Jesus is the Christ? He is antichrist who denies the Father and the Son.”
He is antichrist who denies the Father and the Son
John clearly identifies an “antichrist.” He is someone who “denies the Father and the Son.” Note that this denial also involves the Father. A person cannot reject the Son without rejecting the Father. Denying the Son correlates with denying the Father. One involves the other.
Mt 11:27, “All things have been delivered to Me by My Father, and no one knows the Son except the Father. Nor does anyone know the Father except the Son, and the one to whom the Son wills to reveal Him.”
The ultimate lie of the Devil is to reject the Father’s plan of redemption in the Son. The Devil hates the person and work of Christ more than anything else.
Jn 14:6, “Jesus said to him, ‘I am the way, the truth, and the life. No one comes to the Father except through Me.’”
Antichrists reject God’s plan of salvation in Christ.
Most apostasy starts at denying either the humanity or the deity of Christ. Anyone who claims that Jesus Christ is merely a great teacher, a profound philosopher, or a wonderful religious leader is a “liar.” Jesus is far more than these. He is the Son of God, the Mediator for our sins, God Almighty, and true humanity.
If you refuse to accept Jesus Christ as fully God, fully man who died for our sins, you are a liar. You are someone who undermines God’s plan for salvation. When you deny Jesus as the Messiah, you deny God’s solution for your sins.
