What does Paul mean by being an ambassador for Christ?

In 2 Corinthians 5:20, Paul states, 'Now then, we are ambassadors for Christ.' This concept indicates that he is a representative of Christ on Earth, entrusted with the ministry of reconciliation. As an ambassador, Paul bears the authority of the King and conveys His message of salvation to the world. This foundational aspect of Christian ministry serves to remind believers that they too are called to represent Christ, embodying His love and truth to those around them, reinforcing the overarching theme of the believers’ responsibility to share the gospel actively.
