My own personal belief is that Jesus is the Way, but he has saved even people who don't know about Him. There's a verse - don't know the cite off-hand - where he tells the disciples that he has "other flocks." People who are drawn to the good are by definition drawn to Jesus - the ultimate Good - whether they've actually heard of Him or not. At the same time, Christians have a responsibility to introduce others to Jesus because He wants to enter into relationship with all people.
To that end, I seem to remember many stories of Christian missionaries finding groups of people already essentially believing in Jesus and God in very remote places (down to details that couldn't be just coincidence). The people could never have heard the Truth directly, but somehow they knew. I believe that "somehow" is direct from God.
Amen to that! What do you make of islam and the followers of islam? It's foundational text, the Koran, explicitly states that Jesus Christ did not die on the cros, did not rise from the dead and is not the Son of God.
"I am the good shepherd, and I know My own and My own know Me, even as the Father knows Me and I know the Father; and I lay down My life for the sheep. I have other sheep, which are not of this fold; I must bring them also, and they will hear My voice; and they will become one flock with one shepherd." (John 10:16)
