Jesus died for the whole world, not just for those that beleived in him and followed him.
There is a reason why only God and jesus will judge come the ressurection, because they KNOW.
All will have the chance to know the Father through Jesus, in this life for some and in the next for the rest, the choice will be, as always theirs.
Matthew 25 gives a hint of things that Jesus views as worthy.
Not all will have the chance to know Jesus and some will no a false Jesus and be scarred, they will have a second chance, all will know the Lord and then...ah then...:)
Jesus is THE way because we can't know God except through Jesus, as the term son of man exemplifies one the is "man", the son of God exemplifies the one that is God.
For those that find Jesus while alive, there is a special "life after death" before the "life after the life after death", for those that don't accept or are introduced to Jesus while alive there is the hope at ressurection.
There is grace for all andhope for all for there is love for all.
