Would the bible draw parallels between the spies returning from Canaan and modern biblical criticism?

When the spies returned from Canaan, to verify the kind of land God was going to gives them, all but two said, among other problems, that there was 'big strong men' there. Therefore, if they tried to take the land they would be killed.   Not only did these spies doubt but the whole camp wanted to stone the two spies that had faith, as they hated their blind confidence on being able to destroy those 'big men'. God himself says: >“How long will these people treat me with contempt? How long will they refuse to believe in me, in spite of all the signs I have performed among them? (NIV Numbers 14:11) In light of all this, I am wondering whether we can draw the similarity that many who are exposed to Christianity and feel certain 'doubts' they have are 'too big' to kill are really no different then these faithless explorers (assuming these doubts keep them from faith. ) **Is it fair to say biblically that such cases are just modern intellectual honesty, or would it be reasonable to say biblically it is contempt of God, as in the case of the spies? Where does intellectual honesty turn into wicked contempt from a biblical perspective?** I am only looking for answers that are made from the scriptures. Is this a fair biblical comparison, or would the Bible not draw these parallels?
