When I was quite little, my mother and I went to the movies, and I wanted to sit in the balcony. When we got up there, my mother couldn't move from the back of the balcony. She was so terrified of heights that she was shaking and sweating. I didn't see anything to fear in that balcony, but she couldn't stay there. So we enjoyed the movie from the orchestra level.
That fear is one of various so-called phobias which seem illogical because they're often brought on by situations that pose no actual threat to one's well-being. The danger is generally acknowledged to exist only in the thought of the person, and so any resulting harm to that individual arises not from the situation but from the fear itself.
But consider disease, and the fear that many people have of some diseases in particular. Here there appears to be a real danger. Is the danger real? An examination of Christ Jesus' life and his healing works indicate that the answer is "no." He took the greatest fear there is, fear of death, and proved it to be groundless. Not only did he through the power of Spirit raise Lazarus, who had been dead several days, but through God's spiritual might Jesus revived his own body after his enemies had crucified him.
