First, like I stated in my disclaimer, I don't believe that these will lead a person directly to Jesus Christ (the One True God) and a saving faith in Him. Of course I believe that God Himself has revealed Himself to His creation through various means (i.e. creation itself, Jesus Christ His Son, the Holy Sprit, the Bible as the Word of God, etc...) Not my intention to suggest that world religions contain the "truth".
On the other hand, no anthropologist has ever stumbled across a tribe of atheists. We all have a God-sized hole in us, and I see most world religions trying to somehow fill that hole. I think it is overly simplistic to dismiss all beliefs other than Judaism or Christianity as man "worshipping himself".
Besides, can you really look at almost 2000 years of Christian iconography which portrays Jesus Christ with white skin, blue eyes and blond hair and say that Christians themselves are not just as guilty of making God into their own image?
