How do we know that Paul was a true apostle?

Paul establishes his credentials as an apostle by pointing to the 'signs of an apostle' that were evidenced during his ministry, such as patience, signs, wonders, and mighty deeds (2 Corinthians 12:12). Additionally, unlike false apostles, Paul received direct revelation from Christ and endured significant suffering for the sake of the Gospel. His unique experience on the road to Damascus—where he saw the resurrected Christ—further validates his claim to apostleship. His message and authority reflect not human endorsement but divine commissioning, underscoring the centrality of God's sovereign grace.
