One of the reasons Christ came was so that this could happen. If the Spirit of God can make a virgin give birth around the same time as her aged aunt, and that man can live a holy life, so that we may be reconciled with God, we should not be shocked that the church can have acts of power happen.
Nor should we be surprised when the enemy disavows such as superstition, or (having shredded reason and truth) claims to do such.
12 At the hands of the apostles many signs and wonders were taking place among the people; and they were all with one accord in Solomon’s portico. 13 But none of the rest dared to associate with them; however, the people held them in high esteem. 14 And all the more believers in the Lord, multitudes of men and women, were constantly added to their number, 15 to such an extent that they even carried the sick out into the streets and laid them on cots and pallets, so that when Peter came by at least his shadow might fall on any one of them. 16 Also the people from the cities in the vicinity of Jerusalem were coming together, bringing people who were sick or afflicted with unclean spirits, and they were all being healed.
