a few things about the gospel

Paul, a servant of Christ Jesus, called to be an apostle, set apart for the gospel of God, which he promised beforehand through his prophets in the holy Scriptures, concerning his Son, who was descended from David according to the flesh 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 for the sake of his name among all the nations, including you who are called to belong to Jesus Christ,

  
(Romans 1:1-6 ESV)

 In this short section, Paul manages to cram in a lot about the gospel:

• It is "of God" - the gospel is more about God than it is about us. Do we tend to start with us and work back to God?
• It was promised throughout the Old Testament - God had a plan from the beginning of time to rescue us. The Old Testament is not irrelevant but sets up the promises of God that Jesus came to fulfill. 
• It is about Jesus
• ...who was human - he was descended from David according to the flesh
• ...and also God  - declared to be the Son of God
• it is proved by his resurrection
• it is a gift of grace
• to which we respon in obedience and faith
• it is for all the nations
