Dear saints, let us pray that the saints would proclaim the glad tidings concerning the wonderful person of Christ and His unsearchable riches (Luke 2:10-11; Acts 5:42; Rom. 1:1-4; Eph. 3:8).
Actually, you have to realize that [in Ephesians 3:8] to announce…as the gospel in Greek is just one word. This word is not the ordinary word in Greek for announce, or preach. This is the word that means to announce something as the gospel, to announce something as the glad tidings, or as the good news. Therefore, to Paul, his gospel is the all-inclusive Christ. In other words, his gospel is the unsearchable riches of Christ. In this sense the entire book of Ephesians is a gospel because the contents of the gospel announced by Paul are the unsearchable riches of Christ. His gospel is not just about sin. It is not just about going to hell. It is not just about repenting and believing for the forgiveness of sins that you may be reconciled to God, saved from eternal perdition, and have the eternal life. Even if you include eternal life in the contents of the gospel, still that does not compare with what Paul announced. He announced the unsearchable riches of Christ as the gospel.
