Were miracle stories crafted after Jesus died, and then included just to make Jesus look like a Jewish messianic figure or wonder worker?

The miracles of Jesus were not added to make Him look like a wonder worker. They are included in the Bible because they really happened. God worked miracles through Jesus to reveal who Jesus was during His earthly ministry and there is strong evidence that the miracles were recorded very near the time they were performed. Of course, we trust the accounts because the Bible is God-breathed, but even secular historical ancient books and writings, as well as archeological finds, testify to the accuracy of Jesus’ miraculous works.
