God was performing unusual miracles through Paul.

Even handkerchiefs and aprons he had used were taken to the sick, and their diseases were driven away, and the evil spirits would go out of them.

She said to herself, "If only I touch his cloak, I will get well."

They begged him to let the sick at least touch the edge of his cloak; and all who touched it were made well.

I am telling you the truth: those who believe in me will do what I do---yes, they will do even greater things, because I am going to the Father.
