Matthew 24:5

“Thus says Yahweh, ‘Do not deceive yourselves, saying, “The Chaldeans will surely go away from us,” for they will not go.

“I have come in My Father’s name, and you do not receive Me; if another comes in his own name, you will receive him.

“Therefore I said to you that you will die in your sins. For unless you believe that I am He, you will die in your sins.”

So Jesus said, “When you lift up the Son of Man, then you will know that I am He, and I do nothing from Myself, but I speak these things as the Father taught Me.

Children, it is the last hour; and just as you heard that antichrist is coming, even now many antichrists have appeared. From this we know that it is the last hour.

Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son.
