It is important to note that there are 1.5 billion antichrists in Islam. The single most important fundamental in Mohammedanism, "shirk", is manifest in specific denial that God has a Son. Indeed if a Muslim were to confess that Jesus Christ is the Son of God he would have committed the only unpardonable sin in Islam. They believe that all other sins are atoned for, near or in hell for a spell, before proceeding on to heaven. But declaring that Jesus is the Son of God would result in permanent condemnation according to their false prophet Mohammed.

1 John 2:22 Who is a liar but he that denieth that Jesus is the Christ? He is antichrist, that denieth the Father and the Son. 23 Whosoever denieth the Son, the same hath not the Father: [(but) he that acknowledgeth the Son hath the Father also].

More important to understand is that Islam is to Christianity as the negative is to a photograph. That is to say that Mohammed (channeling Satan who appeared to him as an angel of light) taught them what not to believe as above. Or

Surah 4.157 That they said (in boast), "We killed Christ Jesus the son of Mary, the Messenger of Allah";- but they killed him not, nor crucified him, but so it was made to appear to them, and those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow, for of a surety they killed him not:-

Even the internal evidence within this verse makes it ridiculous. Mohammed is quoting the Jews as saying "We killed Christ Jesus....". If the Jews recognized Jesus as their Christ, or Messiah, then why would they kill Him?

More importantly, not a single Christian for the last 2,000 years ever disbelieved that Jesus was crucified, because if a person didn't believe Jesus died on the cross (to save us from sin), they wouldn't be a Christian. Additionally, as far as I am aware there is not a single sect in Judaism that doesn't believe that Jesus died on the cross. In other words, Christians and Jews have never harbored a doubt that Jesus died on the cross.

Interestingly, while Mohammed/Satan taught Muslims what not to believe, he failed altogether to teach them who did die on the cross. This while at the same time confirming that the event happened. No Muslim can deny that it "appeared" that someone died on the cross. I encourage everyone to go out into Muslim forums and such and ask the simple question "Who died on the cross?". The number of answers you will receive will likely be as numerous as the Muslims you ask. "Jesus asked a disciple to die in His place, to later join Him in paradise, and so God put Jesus face on the disciple, but after He was crucified the Jews realized that the man had Jesus face, but not his body." Or "A Jew went into the house to get Jesus, but Jesus had already ascended into heaven, but when the man came back out of the house, he looked like Jesus, so they crucified him." And on and on in a dizzying array of confusion.

So ironically, while Christians and Jews are in complete resolve as to Jesus' crucifixion, Mohammed's followers are exactly as Mohammed described Christians and Jews "...those who differ therein are full of doubts, with no (certain) knowledge, but only conjecture to follow..."

Thus we see Islam emerge as the only religion whose adherents aren't taught what to believe but rather what not to believe, as the very core of it's doctrine.

Islam is the only anti-another-religion, religion, by design. Mohammed's/Satan's reign/bondage over those poor folks has continued for 1400 years, with another 1/4 of mankind in it's grip as I write. In view of the evidence above, whom might we consider as the false prophet, whose religion is the exact and perfect mirror opposite, of Christianity?
