Uh...where did you get that from?Huh? Are you saying that the Gospel doesn't preach eternal salvation through faith in Jesus?
I said that works are not part of the Christian doctrine of...salvation by grace alone (which is from God), through faith alone (faith is also a gift from God...not something we have of our own that we just decide to exercise), in Jesus alone (God incarnate...the Word that became flesh and dwelt among us who died for us).
That is to say that salvation is not based on any works that can be done by man. Rather, salvation is the free gift of God (see above). In fact, God says that our righteousness (us at our best doing the best things we can possibly do) is like filthy rags (do I need to explain what that means?) to Him.
So, unlike other world religions, Christianity is 100% based on what God has done, is doing, and will do for us...it is that way so no one can boast about doing such and such...its all about God Booty!
