I don't have a King James handy...but I believe that when Thomas said that he wouldn't believe unless he saw a miracle, I don't think Christ hid the marks on his hands and side and told him:
"Thomas! You foolish man! I'm not going to provide you any kind of evidence of God's power and glory; you're just going to have to get by on your own faith, because showing you the rapidly healing hole in my side and the shrinking wounds in my hands would be tantamount to providing proof that there is a God who would do those miracles, and if you have proof, you wouldn't be relying on your Faith, and so you would be worthless to Me, sayeth the LORD."Jesus told Thomas that his faith should be stronger...but He never hid His glory from Thomas; your own example shows God works miracles, and that they are useful teaching lessons for those whose faith is not as great as the Lord would prefer. If the Lord my God wants to allow that miracles occur, and if there are those to whom miracles provide comfort, I don't need the approval of man to believe in them. If God showed Thomas in those elder days, it is perfectly reasonable that there are proofs around us today.
Again, I don’t see the direct evidence to Jesus and the shroud beyond an image.
