“There is one body and one Spirit, just as you were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is above all, and through all, and in you all” (Ephesians 4:4-6).
Before the foundation of the world, the one God and Father of all eternally purposed for His heirs to be one body in Christ and should live holy and blameless lives (Ephesians 1:4-5) once they had been born again by the one Spirit and one baptism (John 3:5). By the gospel (i.e., the one faith revealed by the one Spirit) penitent believers are called out of a life of sin, shame, guilt, and death (2 Thessalonians 2:14) into newness of life when they obey from the heart the form of doctrine authorized by the death, burial, and resurrection of the one Lord (Romans 6:17, 3-4).
As recipients of God’s grace, God’s sons are to walk worthy of their calling (Ephesians 4:1). They are to deny ungodliness and worldly lusts, and live soberly, righteously, and godly in the present age, looking for the blessed one hope (Titus 2:12-13)—eternal life (Titus 1:2): the resurrection and transformation of our lowly bodies into conformity with Christ’s glorious body (Philippians 3:21) and the everlasting deliverance from sin, death, sorrow, tears, and pain (Revelation 21:4).
No rags-to-riches story compares to the one hope offered by the one Lord in the one faith.
