What does the Bible say about the miracles performed by apostolic hands?

Miracles performed by the apostles, such as those seen in Acts, served as signs to authenticate the message of the Gospel and the authority of the apostles. These miraculous acts were not an end in themselves but were intended to direct attention to the truth of Christ and His sacrificial work. As Hebrews 2:4 states, God bore witness to the Gospel with signs and wonders, confirming its legitimacy. Importantly, these miraculous gifts were temporary and were meant for the specific epoch of the early church to validate the apostles' teaching. Over time, as the New Testament was completed and the church matured, the focus shifted from miraculous signs to the preaching of the Gospel, which remains the primary means by which God effects salvation.
