Just because God's chosen ones were led astray does not mean that no one else can enter the kingdom of heaven.

All it means is that Satan was focused on getting God's chosen people to chill with him in hell and in the process left out the Muslims

Another argument could be since the world super powers run on Christianity then it would be easy to corrupt the rest.

Its a futile search. Just seek God. Christians are and will always be human, prone to err and confusion. In fact if you manage to get the true Christians (those who are perfectly on the way) do not join them because you may infect them with your confusion. If it is fellowship that you seek, fellowship with fellow seekers for no single group has the bragging rights of being the 'truly compliant Christians'.

Word of advise... Pentecostals are closer to what you are seeking. Keep your search around there...

I know you've been upset with what you're seeing in Christianity. I was a Christian too. I used to get more upset after church service. The things I see them doing does not match what their book says. The things the preach, does not match they do...

Let me tell you what you should be seeking:
I believe in God
After that obey the commandments, and abandon the things that are forbidden.

So the question is: "What is Islam?"
Islam is abstinence & Obedience to God

When you read history
..you realize that God Has sent among every community and nation a Messenger.
These messengers told the people: "Worship God (Alone), and avoid (or keep away from) all false idols, etc.
They told them do not worship other beings besides God.

But some of them were guided correctly, and some of them strayed from the correct teachings.

They even changed the scripture:
Read about Constantine the Great and Nicene Creed (Nicea Creed).

You can see in the land what has been the end of those who denied the truth.

Surely, the true religion is the one the asks people to submit to God.

You can see those who were given the Scripture Jews and Christians have differed out of jealousy.
Yet knowledge had come to them.

You can see the proofs, evidences, verses, signs, revelations of God.
Then surely, you can see for yourself what is right among all these religions.

God has provided to people the same religion which He ordained to Noah, the same He inspired in Muhammad (pbuh).
And the same which He ordained for Abraham, Moses and Jesus.
God told them they should establish religion, to do what He order them to do practically.
And not to start divisions in the religion i.e. various sects in religion.

Where does the Bible say that?
John 14:6 says
I am the way and the truth and the life. No one comes to the Father except through me ...there doesn't seem to be any ambiguity whatsoever in that statement. Soon as Jesus was crucified, those are the words that apply. Between that time and when the first missionaries arrived, some 1900 to 2000 years had passed, and our African ancestors had never heard about Jesus. @kiterunner's question still remains unanswered. I posed this to a pastor once, and despite years of preaching experience, he could not provide an answer.

Meduza, you have referred me to the holy book which I read.

That holy book talks of a remnant people of God (a small part or portion that remains after the main part no longer exists).

There remains just the simple matter of finding them.

Do not discount history. I disagree with you there. Its our duty to dig into the past if we are to know and understand the present and future.

Failure to find the ark or grail shows better use could have been made of time and resources, like sticking to the faith instead of changing and modifying it.

Its not too late to learn from them and major on the majors instead of major on the minors.
