This argument shows that while Christians can surely be invited to believe in the truth value of propositions that have biblical justification only, they cannot ‘know’ that these propositions are actually true.

Every biblical divine assertion concerning the necessary and sufficient conditions for one to be saved would be a prime example of an assertion that has biblical justification only. Everyverse regarding the nature of and relationship between Jesus and God also falls into this category .

If christians aren’t in a position to place probabilities on whether or not God has morally sufficient reasons beyond their understanding to lie to them, then Christians are in no position to place probabilities on the truth value of these biblical claims. If Christians aren’t in a position to place probabilities on the truth value of these biblical claims, then Christians can’t ‘know‘ that the essentails of Christianity are probably true or probably false. The actual truth of much what C.S. Lewis deemed ‘Mere Christianity‘ must be completely inscrutable to a Christian thinker. While not necessairily being a problem for justified belief in a god, it is certianly a problem for justified belief in the Christian view of God – which entails things like the salvific significance of the death and resurrection of Jesus Christ two thousand years ago.
