...even though you and I both agree that Jesus is our Risen Lord, I don't really agree that the "evidence is clear." If it were, people would be lining up in droves to get into the Kingdom. The reality is that even in the Bible itself, we are given indication that God has purposely presented prophetic images in epistemologically
obscure ways. In fact, people--even the Israelite/Jewish people--haven't been necessarily privy to understanding all that God has had planned.
So, when we speak about the 'truth' of the Gospel of Christ with non-believers, we need to keep the above in mind. Too often, I see many fellow Christians who present the Gospel as an obvious option when it really isn't.
Furthermore, and in direct relation to the OP, we see Jesus indicating that relationships with loved ones, even those who are dying or who have died, can stand in the way of one's decision to accept Christ. In fact, I have a mother-in-law who is not a Christian, and because her relationship with her own dearly departed mother was so strong, she really can't find it in herself to just 'skip on over' to the Christian faith because she knows that to do so would be to have to accept the strong likelihood that her mother won't also be present with her in eternity. So, she basically rejects the proposition that Jesus is the "only way," and she does this for what seems to be the very reasons implied by Jesus.
With all of this in mind, it would probably be wise for us to be circumspect in how we present the Gospel of Christ since not only are portions of it obscure, but it is very psychologically challenging to many people all by itself, and this is without our additional aims to make it even more socially pressurized.
