What problem faced Barnabas?

Barnabas faced challenges related to his role as a leader and supporter in the early Christian community. One significant issue was the skepticism some members had about accepting Paul (formerly Saul) after his conversion, fearing his past as a persecutor of Christians. Barnabas advocated for Paul, vouching for his genuine transformation and helping him gain acceptance among the apostles. Additionally, he encountered disputes, such as the disagreement with Paul over John Mark, which led to their separation.
