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.

Peter's miracle of healing the beggar at the Temple gate is a thrilling moment that highlights transformative power and faith. Let’s imagine this scene: a man crippled from birth, begging for alms, must’ve watched countless worshippers pass by, givers and takers emphasizing the disparity between his suffering and their abundance. It’s this intimate setting at the Beautiful Gate that creates an electric atmosphere. Peter, filled with the Holy Spirit, doesn’t give the expected coin but instead offers healing in Jesus’ name. This action not only restores the beggar’s physical1 strength but bridges a connection to divine possibility, much like the times Jesus turned taunting despair into joy through his own miracles.

What’s notably fascinating is that Peter's action parallels Old Testament miracles, like those of Elijah and Elisha, which showcased God’s power through human agents. Just as they had protested if Yahweh was near (1 Kings 17:21; 2 Kings 4:35), Peter enacts God’s unfolding purpose through faith-filled proclamation and reception of healing. This healing at the temple embodies a new dawn for the early Church — previously unheard opportunities and boundless potential unleashed.

Additionally, for many first-century observers, witnessing such miracles lent credibility to the burgeoning Christian movement, proving that God still acted in direct ways among His people. As followers of Jesus began to experience miracles and mesmerizing testimonies, it foretold the courageous spread of Christian belief long after Peter and the other pillars of the faith had ascended into martyrdom. Each miracle wasn’t merely a spectacle but served as a testament to faith's enduring capacity to evoke hope, healing, and courage amidst adversity. Think about it; this moment launched a surge in the miraculous nature of the faith that resonates deeply across centuries!
