On his third missionary journey, Paul spent three years in the region of Ephesus constantly admonishing the Ephesians with tears. In this passage (Acts 20:17-38), Paul recounts his time in Ephesus to the Ephesian elders and passes the torch to them to continue in his example. As he does, we see that Paul spoke consistently of repentance toward God and faith in the Lord Jesus Christ (Acts 20:21) because he believed that "the word of his grace" was able to save and build believers (Romans 1:16).
His single-mindedness explains why the New Testament is, first, a document describing the multiple facets of the Gospel (1 Cor. 15:1-3) and not a manual for making life work. Gospel truths light up the dark places of our soul (2 Cor. 4:4,6) and build us up for our inheritance (Acts 20:32). Therefore, a deepening understanding of Christ and Him crucified (1 Cor. 2:2) should be the central focus of spiritual life. This message attempts to examine the multi-faceted beauty of the Gospel on display in Paul's epistles.
