The use of the phrase signs and wonders ties the work of the apostles to the prayer from Acts 4:30, possibly also connecting their work to that of Moses (Deuteronomy 34:10–12).¹ The phrase itself simply refers to miracles, in this case miracles of healing and exorcisms (Acts 5:16). Even though Peter will be mentioned by name (Acts 5:15), we are to understand that all of the apostles were involved in preaching and performing miracles of healing.² These miracles were meant to authenticate the apostles as eyewitnesses to the risen Christ and affirm the fact that the new Messianic age has arrived.³ Typically they would involve the apostles placing their hands on those who were sick (see Acts 3:7; Acts 9:41; Acts 28:8). We should remember that the apostles were instruments and not agents of miracles. That is to say, Jesus Christ was working through them; he is ultimately the one who does all the healing.
