I think you make a mistake in comparing Islam and the West for one thing the West is not a religion or just one nation, it comprises of many things which does also include Islam because of some western people who have choosen to become muslim. Islam is pretty much on its own and is not a place.  Now if you say Christianity and Islam yes you may have a point, but it seems you have equated the West as Christian because you mention "their religion" the west is not Christian (even thou it comprises more of the religion), this is like saying that the east is Islam, which it isn't, the East also comprises of many religions and nations, the East is not a religion either so you can't say they are moving away from their religion (if they are).

If might be better to rephrase it: It is quiet surprizing to note that Christianity is making progress by moving away from the teachings of their religion but we are lagging behind because we are moving away from the teachings of our religion.

From what I know, Christianity had to change for it to stay, it realised that to keep the people some things had to change and change with the times, a religion is dependent on its folowers to survive. Islam needs to do the same. And Islam also needs a central body like Christianity to regulate those changes in a proper way otherswise people will make their own interpretation left right and centre, and it seems some people will make fatwas whether they are in a position do so or not. I truly think if their was a central body, then places like some places in Africa who are islamically run but do things in a corrupt way, just look at Sudan and most of the Middle east would be in line with the same teachings, Arabia wouldn't be so different to Iraq or Afghan since things would be the same, and those living in the west would also be inline with middle east and Sudan. The Catholic church is pretty much run the same with the same regulations and with any changes posed it has to go before the vatican, but Islam and mosques do not have this, so teachings would go by the way side, scholars can only do so much and then it is sort of by their own interpretations and understandings.

Anyway, just my thoughts and I'm sure there is room for improvement, and another thing Islam needs to compromise on some things and this Islam, or should I say muslims will not do. If you are in a relationship with another and a need to co exist, compromises need to be made. 

Islam is not really a nation  if it were then it should be in one place/country with the country name Islam

We should first get rid of our fear of death and love of this world.
