Baptism and Testing of Jesus (Mark 1:9-13)
Mark 1:9-13 describes the baptism and temptation of Jesus. The Gospel of Mark binds these two events causally close.
The story in this passage highlights Jesus' identity as the Son of God and his ability to resist the temptation of Satan. The role of the Holy Spirit, which descends on Jesus upon baptism, is especially stressed here. He is a token of God's authorization to the service and an agent that leads Jesus into the desert.
These events mark the beginning of Jesus' public ministry and set the stage for his teachings and miracles in the rest of the Gospel of Mark.
