Is Jesus the Only Way?

Are all religions different paths up the same mountain? Or is there only one way? Is this way Jesus? There are so many religious views, so many different possible ways, which is the most convincing? Which one works?

Exclusive or Inclusive
In general, these are the two types of religious view, that either they are the only way, or all religions provide a way. One popular argument is that all religions are different parts up the same mountain. However, there is a fundamental flaw in this view because to know that this is truth, you have to not only have reached the top, but also see the whole of the mountain. In other words, you are claiming divinity. If we are to take an inclusive view, we would have to accept that religions such as Islam, Judaism and Christianity are true in their views, so, we end up at position of exclusivity.

Why Jesus?
The fundamental problem according to all exclusive religions is that of sin. To be with God, one must be righteous in His eyes. All have sinned so it is a problem which all mankind faces. The reason God cannot be with sin is because He is perfect and just, He cannot be with sin otherwise He would be denying His own nature. This is where Islam falls, there is salvation only in Allah but there is no remedy for sin, which demands punishment, death. This is where Jesus comes in, He lived a sinless life and gave up His life as a sacrifice for sin, once and for all. It is the same case with Judaism, the law was never supposed to be permanent. In fact, Abraham, the father of the Jews was accredited with righteousness not because He followed the law, but because He had FAITH in God. Therefore, by the same logic, we can only get to God through faith in God, that is, through Jesus Christ.

Paul sums up all the arguments very comprehensively in the book of Romans.
