The mission is to build strong marriages using God’s model of the relationship between Christ (The Groom) and His church (the Bride).
In Ephesians 5, Paul lays out the roles and responsibilities of the husband and wife toward each other. The wife seeks to submit and respect her husband while the husband should seek to love, cherish, and sacrifice for his wife. After laying out the roles and responsibilities, Paul ends the chapter by concluding he is really referring to Jesus Christ and the church. This means that the marriage between a husband and wife has as its primary purpose to reflect the relationship between Jesus Christ and the church.
