I imagine some were just the normal urge we all feel at times to help out. For example, we might volunteer to make the beer run or bring extra food to a pot luck supper. Others seem to be motivated by an urge to help someone in pain or suffering.
If the miracles actually happened, I would imagine they were motivated by the same things that we experience today. That He was more successful than you or I might be simply shows that like a great athlete he was better at praying than we are.
Remember, if the miracles happened they were not done by Jesus but by GOD through him.
And I doubt that they really could be called evidence. Even if they were done in the presence of James Randi, I think the best we could hope for would be a decision that it was unexplained.
I think the important part of the miracles is not whether or not they happened or even if they were miraculous as opposed to magic, but that they teach us a lesson.
We are charged to try to do what is right with the capabilities given us. Maybe I cannot perform miracles, but perhaps I can help feed someone, or bring joy to a festive occasion, or comfort someone who is sick, or through the World Grid Project help develop methods to screen for cancer or find a new drug for diabetes.
Do the miracles invalidate faith? I don't think so.
