The answer is: Paul

Acts 9:15 - The Apostle Paul, originally known as Saul of Tarsus, played a crucial role in early Christianity despite not being one of the original twelve apostles. After his dramatic conversion, he became a leading missionary, paving the way for spreading the Gospel to the Gentiles (Romans 11:13).

The Apostle Paul is an exhilarating figure in the New Testament tapestry, and his journey from persecutor to proponent of Christianity makes for riveting storytelling! Although not one of the original Twelve Apostles, Paul stands out in the early Church's unfolding narrative as a powerhouse of letters and mission work. Imagine Saul, striding through Damascus with intentions buzzing in his head, when suddenly he's blinded by divine light and transformed into Paul - talk about a plot twist!

His letters, many of which make up substantial portions of the New Testament, echo the ideas of inclusion and the universality of faith. Paul articulated the belief that the message of Jesus transcends cultural and religious barriers, treating Gentiles not as outsiders, but beloved participants in God's family. His support for the Gentiles, which he famously defended at the Jerusalem Council (Acts 15), allowed love and grace to push aside old discriminatory customs.

One cool biblical tidbit: did you know Paul was a tentmaker by profession? This meant he seamlessly connected with diverse groups, using that craftsmanship as he traveled throughout the Roman Empire. Envision him weaving away while sharing the good news, inviting digits, skills, and stories into a vibrant faith community. So even while Paul’s apostolic identity shifted from one active faith leader to another wholly committed to the cause, he paved paths that forever changed the ancient world and shaped contemporary Christian thought!
