During his lifetime, Jesus himself didn't call himself God and didn't consider himself God, and ... none of his disciples had any inkling at all that he was God. ...
You do find Jesus calling himself God in the Gospel of John, or the last Gospel. Jesus says things like, "Before Abraham was, I am." And, "I and the Father are one," and, "If you've seen me, you've seen the Father." These are all statements you find only in the Gospel of John, and that's striking because we have earlier gospels and we have the writings of Paul, and in none of them is there any indication that Jesus said such thing...
But if you think about it for a second, it makes sense that the empty tomb wouldn't make anybody believe. If you put somebody in a tomb and three days later you go back and the body's not in the tomb, your first thought isn't, "Oh, he's been exalted to heaven and made the son of God." Your first thought is, "Somebody stole the body." Or, "Somebody moved the body." Or, "Hey, I'm at the wrong tomb." You don't think he's been exalted to heaven. In the New Testament it's striking that in the Gospels the empty tomb leads to confusion but it doesn't lead to belief. What leads to belief is that some of the followers of Jesus have visions of him afterward.Read complete article over here.
