Here is an excerpt from a previous online discussion I was involved with:
Most people reading this (in the UK) will have a version of Christianity ... from Ma and Pa. Not many will be Zen Bhuddist, for example. But the Zens also get it from their parents. In the words of the old graffito "Religion, like life, is a sexually transmitted disease". Statistically, never mind any otherwise, it's pretty unlikely that we just happen to be hearing about the one true religion from our own mum and dad.
Next, as e.g. Jacob Bronowski pointed out, there is a wide range of religions on offer, each with definite claims to their being the only true one. Obviously, even on their own terms, all but one of them must wrong. Statistically (again) therefore, it's highly unlikely any one of them is right. Logically, you have to reject the lot.
So this is the question I want to examine next: Does the presence of a plethora of other religions invalidate the claims of Christ? Is Christianity just another religion? And, If there is only one path to God, how can we be so sure we have found it? Is there more to faith than just a "geographic lottery" as the above writer would suggest?
First, lets examine this from a purely logical point of view. If you are presented with a set of mutually exclusive statements (about anything) there are only two logical alternatives: either they are all wrong, or only one is correct.
[This is the fallacy in modern "political correctness" about religions. The only way they can all be of equal merit is if they are all equally wrong! This is nothing more than atheism dressed up in the guise of religious "tolerance". Being tolerant of other people irrespective of their beliefs is a good thing (just so we are clear on that!) but the pretence that everyone's opinion is equally valid is pure nonsense!]
However, the logic that the more alternatives there are the less likely that one will be correct is totally wrong. If anything it is the other way round. If a statement (about anything) is true, then it remains equally true regardless of how many false statements are made in opposition.
So if Christianity is true, if what Jesus claimed about himself and recorded in the Gospels is accurate, then it is not affected one jot by the presence of other religions. Christianity stands or falls in the claims made by the historical person, Jesus of Nazareth.
So what did Jesus claim? Well the first thing to note is that Jesus was not keen on religion and religious types. The last thing Jesus came to do was to institute "just another religion". If his mission had been as banal and inconsequential as that, they would never have crucified him! What he came to do was to restore relationship with God. (If you are confused what the difference between religion and relationship with God is, let me point you to a couple of excellent articles my friends Ricky and Mark have recently posted on the subject.)
Next, Jesus did not claim to have one of may ways to know God. He claimed the one and only way. More than that, unlike every other religious leader, he did not just claim to know that way, he claimed to be the way.
Jesus said to him, "I am the way, and the truth, and the life. No one comes to the Father except through me." (John 14:16)
This faith in Jesus is passed on, not by family tradition, or by church attendance, but as each one individually accepts the claims of Christ and surrenders their life to him. The fact that your mum and dad believe in Jesus means nothing if you do not choose to bow the knee to him yourself.
Finally, there is no geographic boundary to the Gospel. Jesus gave clear instructions that his disciples were to take it to the people of every nation, tribe and tongue.
How do we know that we have found the truth? We know because the Gospels, other historic evidence, and millions of transformed lives all over the world proclaim: Christ is risen indeed!
In the past God overlooked such ignorance, but now he commands all people everywhere to repent. For he has set a day when he will judge the world with justice by the man he has appointed. He has given proof of this to all men by raising him from the dead. (Acts 17:30-31)
