The answer is: Peter

Acts 3:6-7 - Peter was the first apostle to perform a miracle after Pentecost, healing a beggar at the Temple gate. This act demonstrated the power of faith and set a precedent for apostolic authority in miraculous signs, echoing Jesus' own miracles and foreshadowing the spread of Christianity throughout the world.

When Peter healed the beggar at the Temple gate, it was not just a striking display of divine power but also a transformative moment in the life of early Christianity. Serving others and communities was not a random act but a resurrection of the spirit bestowed by Jesus. This miracle at the Beautiful Gate harmonizes beautifully with Jesus’ promise in John 14:12, that those who believe in Him will do greater things than He did. What an ambitious boost to the confidence of the apostles!

Consider this: the Temple was interconnected to the Jewish identity, and this miraculous act was not just to showcase Peter's abilities but to reaffirm the continuity of God’s work from the Hebrew Scriptures to the clinical hands of the apostles. The beggar’s restoration echoes several stories from the Old Testament, notably the miraculous healings by the prophets like Elisha. These connections enhance our understanding that early Christians didn’t see their faith as entirely different, but as a fulfillment of what came before.

Miracles played an essential role in attracting the attention of skeptics and seekers alike. Each act of healing and compassion was an invitation into a new way of life—a departure from mere adherence to law towards a living faith enriched by grace and communal support. Peter's healing was thus not just a personal gift but an emblem of collective potential! It hinted at the unfolding mission to heal both individuals and communities through faith in action.
