Acts 20 provides a biographical overview of the life and work of Paul in serving the Lord and His church. At least six times in v. 17-35 , the phrase "You know" or "I know" is used to make declarations of facts regarding Paul's life of service. Summarizing the key points: 1) Paul was with the brethren constantly 2) served with humility and endured much opposition 3) preached to both Jews and Gentiles 4) "completed" the task of testifying to the gospel of God's grace 5) innocent of the blood of all men, since he did not hesitate to proclaim the whole will of God to all everywhere 6) warned of "savage wolves" that may infiltrate and draw believers away 7) supplied for his own needs and those of his companions 8) by working hard, was able to help others in need. There are also at least three challenges that Paul gave to the church leaders before his departure : 1) Keep watch over yourselves and the flock 2) Be shepherds of the church 3) Be on your guard and remember his many repeated warnings. The final quote in v.35 of Jesus is a fitting summary of Paul's life of self-less giving in the work of sharing the good news. "It is more blessed to give than to receive".
