There is a reason why many Christians around the world have latched so quickly and tenaciously onto the discovery of what may be the ossuary or burial box for James, the brother of Jesus. There's a reason why every time archaeologists discover some inscription referring to King David, Pontius Pilate, or some other biblical figure that this news immediately makes a splash in the pages of Christianity Today. Here, we are told, is further "proof" that the stuff in the Bible really did happen! There's a reason why there is now a huge enterprise that is literally scouring the universe for evidence that the formation of the cosmos required the hand of a Creator God. It's not just that we want to meet evolutionary and atheist scientists on their own turf--most folks also quietly hanker for something tangible that can bolster the confidence they have in their faith. Over and again we find ourselves wanting more.
Jesus himself knows that faith is both a blessing and a miracle. That's why he says in verse 29 that while it was one thing for Thomas to believe with Jesus standing right in front of him, it would one day be quite another thing to believe without such undeniable physical proof standing in the same room.
