Sad to say, that even if she did suddenly sit up in bed, the world would still go on as it does. Atheists would not fall on their knees. Remember the story that Jesus told about the rich man and Lazarus who was in Abraham's bosom? Remember how he begged to come back from the dead so that he might warn his brothers because surely they would believe? It is found in Luke 16:19-31. This was the answer Jesus gave in the story to the dead man's request:
But Abraham said, `They have Moses and the Prophets; let them hear them.' 30 "But he said, `No, father Abraham, but if someone goes to them from the dead, they will repent!' 31 "But he said to him, `If they do not listen to Moses and the Prophets, they will not be persuaded even if someone rises from the dead.' "
So, sad to say, even if Terry miraculously by His Hand would regain her mental and/or physical abilities, as much as we want to think that this would make all bow at the name of the Lord, it simply won't happen. Jesus Himself said this is true. If not, then all the world would follow Him at the miraculous sign of His resurrection, much less all the other miracles He performed. But like you, I would also love to see this happen.
The post A.D. 33 world has Moses, the Prophets, and One who is Risen from the dead.
What is our excuse?
