I am sure we have heard a lot on the "Lost Tomb of Jesus". The documentary which I have not seen myself has been upsetting some and not because it seemed to be true but the pathetic amateurish scholarship found there.
However, my gig is tangential to that. I am more and more getting convinced that in the same way that in Eph 2:8-9 says that faith is a gift, I am also convinced that believing in the testimony of Scripture alone.... is a gift too! What prompted me to entertain this idea is based on lessons I have learned from my friends who deny Sola Scriptura. However, today that idea got re-inforced when I listen to the excellent treatmeant of Pr. Tom Baker on his program Law and Gospel found here. In this program, Pr. (Dr.)Baker was reacting on the "Lost Tomb of Jesus". I highly recommend for your listening edification.
To jump ahead - the point is John 20:24-29. Pr. Baker says that he had no desire to appear rational to the world because our faith is foolishness to them, appealing to material evidence is a "milky" was of defending the faith. Rather, the lesson is found in Thomas' experience, in that passage there Jesus said to him - "blessed are they who have not seen and yet believe".
Come home now to where we live. We have no evidence that Jesus' death was for our sins, only Scripture says that. We were not there at that time and place. You find no proclamation of that except from Scripture. Hence, since believing the Gospel promise is a gift and since that promise is in Scripture alone and in no other evidence, then believing Scripture is a gift too, absolutely it is.
It is futile exercise to look for hope somewhere else or even withing what is in ourselves, if the Scripture promise does not suffice, nothing else will.
