No, according to our personal epistemic 'tastes,' we think there's no "good" reason for God to withhold such information from us. Really, whether something SHOULD be one way or another will depend on the person who is wanting to be so informed and to have that information delivered in a certain way. But then again, you're talking to a person (me) who is an Inclusivist and not an Exclusivist. I don't necessarily think a person HAS, in all instances, to hear about Christ and then make a specific, so-called personal response to the Father and Jesus and the Holy Spirit as He is in Himself in order to be saved. No, I think Christ's Life, Death and Resurrection could possibly extend to any person who, even apart from a specific knowledge about Christ, reaches out to God as He IS (and not specifically as Vishnu, Buddha, or trust in some other erroneous conceptualization about God, such as the one that Muslim's have) and Christ's Grace could be extended to that person.
In other words, there could be some lone young man in India at this moment who is contemplating the shortcomings of Hinduism and is thereby, even though not informed about Jesus, reaches out existentially to that one True Being, Creator of All, God of All, who Is as He is and is not as he has been told God is, and asks for whatever mercy and hope that God might bestow upon Him. In such a case, particularly if that lone young man, let's say, is close to death, could very well still be covered by the Grace of Jesus Christ.
(And yes, yes. I know. Jesus says in John's Gospel that those who believe will be saved, and Paul says that belief in the Gospel of Christ comes by hearing and all that......I get that. I'm just saying that while God does have a main mode and plan for spreading His Gospel into the world, that however, those like Abraham who did not really know of Christ yet had faith in God as He is, then those perhaps who have come after the time of Jesus' first advent could, potentially, although not certainly, be covered by Christ's grace through a faith that discerns the difference between local customs about the divine and the biblical sense of God).
However, those who have a reason to fear are those who, like the Pharisees of old, have been definitely given a specific and epistemically clear enough message about Jesus, with no real misunderstanding, but they yet utterly refuse to come to Jesus ................................................................. those are the ones who are in trouble.
