Paul once more points out his unworthiness to serve the Lord and His people, then he calls the gospel "the unfathomable riches of Christ” and explains God’s eternal purpose in the gospel.
Paul continues on with the concept of unity within the church by pointing to his own undeserved ministry to the Gentiles and to the revealed mystery of Gentiles being joined together with Jewish believers in the church.
God shows magnanimous grace toward those who have transgressed against Him, treating them as He did his only begotten Son, Jesus Christ, by raising them up and making them spiritually alive.
