Scripture states that Elijah, Peter, Jesus, and the other apostles' power didn't come from themselves. They are described as men empowered by God, but not God. Why do you not believe God can empower people to do miraculous things?
Acts 10

38how
God anointed Jesus of Nazareth with the Holy Spirit and with power, and how Jesus went around doing good and healing all who were oppressed by the devil, because God was with Him.
