Good post, but it’s John 14:6. I once gave a message at a biker church where the pastor had t-shirts printed up with John 4:16. I asked him what the verse was, and he said this one. He was more than a little embarrassed that no one caught it...
Yes, there are many antichrists, even though the term has come to refer mainly to the “Son of Perdition” who has been prophecied.
Even Peter seems to have succumbed to the antichrist spirit momentarily:
“31And he began to teach them, that the Son of man must suffer many things, and be rejected of the elders, and of the chief priests, and scribes, and be killed, and after three days rise again.
32And he spake that saying openly. And Peter took him, and began to rebuke him.
33But when he had turned about and looked on his disciples, he rebuked Peter, saying, Get thee behind me, Satan: for thou savourest not the things that be of God, but the things that be of men.”
