'Anti christ' in the Bible

My Children, these are the last days. You were told that an Anti-Christ was coming; and many Anti-Christ's have already arisen. By that we know that these are the last days.

Who is a liar, if not the man who rejects the truth that Jesus is the Christ? He is the Anti-Christ--The man who rejects the Father and the Son.

while all inspiration that does not acknowledge Jesus is not inspiration from God. It is the inspiration of the Anti-Christ; you have heard that it was to come, and it is now already in the world.
