How do we know apostleship is true?

The truth of apostleship is grounded in the direct calling by Christ. According to Mark 6:7, Jesus called the twelve apostles personally, endowing them with authority and responsibility. Their ministry was affirmed by miraculous signs and wonders, which served to verify their divine appointment. The acts they performed, alongside their teachings, were integral to the establishment of early Christianity, distinguishing them from regular teachers. This divine calling is in accordance with God's sovereign purpose and reflects both their significance and the unique role they played in the early church.
