Back in biblical times, people did not say someone like Jesus did spellwork. Instead, spellwork would have been labeled as calling for a supernatural blessing and or a miracle. But what is a miracle?
A miracle is a blessing and welcome event that cannot be explained by natural or scientific laws and is therefore considered the work of divine authority. And for the record, magic and miracles are the same things.
Yet to the mainstream religious folks, they like to say there is a big difference between the two terms. It is fair to say that Jesus performed miracles, but religious folk claim it would be wrong to attribute his magical works to magic. And that is pure pish posh.
