Mark begins his gospel account of Jesus’s life with a direct statement:
The beginning of the gospel of Jesus Christ, the Son of God.
The beginning means the starting point. And Mark begins with the beginning of Jesus’s ministry and message as the starting point for his gospel narrative.
Perhaps the reason Mark begins his gospel account at the beginning of Jesus’s ministry is because he is introducing Jesus to the Gentile world. (More about this later point will come further into this commentary).
