What does the Bible say about the work of the apostles?

The work of the apostles is primarily outlined in the New Testament, where they are described as instruments of God chosen to spread the gospel of Jesus Christ. In Romans 15, Paul writes about his ministry, emphasizing that he will only boast in what Christ has accomplished through him. He highlights that it was not his efforts but the Spirit of God that enabled him to preach effectively and lead others to obedience. The apostolic ministry is confirmed through signs and wonders, which were fundamental to establishing their authority and the truth of their message. Additionally, Acts and Hebrews affirm that God bore witness to their ministry through miraculous acts, further validating their role in building the early Church.
