Romans 1:1-6 and 16:25-26.
How the book of Romans begins. Paul, a servant of Christ Jesus, called to be an apostle, set apart for the gospel of God, which he promised beforehand through the prophets in the Holy Scriptures, the gospel concerning His Son, who, as to his earthly life, was a descendant of David, and was declared to be the Son of God in power, according to the Spirit of holiness by His resurrection from the dead, Jesus Christ our Lord, through whom we have received grace and apostleship to bring about the obedience of faith among all the unreached peoples  for his name’s sake, including you who are called to belong to Jesus Christ.
How the book of Romans ends. Romans 16:25-26 Now to the one who is able to establish you in accordance with my gospel and the proclaiming of Jesus Christ, in keeping with the revelation of the mystery hidden long ages past, but now revealed and made known through the prophetic writings by the command of the eternal God, so that all the unreached peoples might come to the obedience of faith—to the only wise God be glory forever through Jesus Christ! Amen.
 Obedience of faith: ὑπακοὴν πίστεως. See Romans 16:26.
