A quick thought...have you heard the windowless room illustration?
It runs like this...Imagine you're kidnapped, blindfolded and the next thing you know you're in a featureless, windowless room with some other people. Nobody knows how they got there, or what is on the other side of the walls, but speculation is rife. However, we can find out once someone from outside enters in. That is a bit like us in the world and Jesus coming in the flesh.
While great at pointing to Jesus as the person who reveals the truth about God, the illustration has some serious problems.
- It does not seem to have room for Psalm 19: "the heaven's are telling the glory of God". In the Bible it seems like the world is not a dungeon, but a greenhouse through which the glory of God shines clearly.
- It makes the primary mission of Jesus seem like it is one of revelation and not salvation. Agnostics and atheists may think the main question is 'how can I know the truth about God?' But the Bible gives little attention to that question in comparison with 'how can I be saved?' So far as it does address the first question, it is through answering the first question.
