Ans.01. The church he left was the church of Christ and his teachings were handed down by those who were taught by him, by those who acknowledged he was the son of mankind by divine right. and so spawned Christianity.
02. But of cause the devil wouldn't have this, the devil started many religions under the guise of Christianity so as to confuse man on his path to righteousness.
03. The Christian bible speaks of many false religions and prophets that will show up under the guise of Christianity to redirect man from the one true path.
04. ut a genuine man seeking a true path to god will see the righteous path..........and guess what ? islam isn't it.
01. Jesus left the world "all of a sudden and in a hurry" and never did "organized" his so called Church. He preached in Jewish Synagogues and in open spaces.
After his death his chosen disciples tried to continue his mission, but they were very much convinced that "end of world is near and Lord's return is imminent.
02. You are right, the Devil would not tolerate that any Prophet's mission should be completed unhindered, and he tries to mislead people.
In case of Christianity he did it thru St. Paul, a person who had not known Jesus Christ at all…. It was thru him that Devil introduced the concept of Divinity of Jesus Christ, the idea of Original Sin and Jesus dieing for the Sin of humankind and concept of Living Under the Grace.
Jesus did not preach any of these ideas during his entire life, but because of "efforts" of St. Paul, they became the "Fundamental article of Faith" for Christianity.
03. Jesus did speak of "many false prophets to come after him" but at "No Place" Jesus said that he is the Last and Final Prophet!! He gave a test to distinguish between a True prophet of God and a False prophet of God.
Jesus while going away about "Another Comforter" who will come after him and guide people to "All Truth".
04. Any "unbiased and free minded person" when he or she studies teachings of Our prophet and his true life history" would be "more than convinced" that our prophet was a Genuine Prophet of God and he was the one which Jesus talked about as "Another Comforter".
Hundreds and thousands of Christians (including their Scholars and Priests have come into fold of Islam in past 1400 years and many more are accepting Islam every day.).
That is why islam is the fastest growing religion in the world today and it is growing in almost every Christian country!!
I have collected many such stories of new converts to Islam, you can view them by link given below:
This is a sample list and there could be many times more people who have accepted Islam in past 100 years. Only God knows their exact numbers.
How many were convinced of the truth of islam, but did not have "moral courage" to come forward and declare it, only God knows their numbers.
The "die hard" believers of St Paul like yourself and your friend Shielaa the Great have to answer many Questions when you confront Jesus in the hereafter!!
May be your post is a cue. I will start posting the Journey from Christianity to Islam by Capt. Odonga
