The message begins by looking at the words and works of Jesus, followed by a consideration of the same in the life of Paul. Both of them gave their lives totally for the sake of others. As Christians, we are to do the same.

35 In all things I have shown you that by working hard in this way we must help the weak and remember the words of the Lord Jesus, how he himself said, ‘It is more blessed to give than to receive.’”
Acts 20:35 English Standard Version (ESV)
