At Jesus’ baptism, a voice came from heaven saying, “You are my beloved Son; with you I am well pleased” (Mark 1:11). Mark places this statement at the start of Jesus’ public ministry.
In Mark 1:9–13 Jesus comes from Nazareth in Galilee to the Jordan and is baptized by John. As he comes up from the water, he sees the heavens opening and the Spirit coming down on him like a dove, followed by a voice from the sky naming him God’s beloved Son and expressing pleasure in him. This scene follows Mark’s opening announcement and John’s ministry of baptism and preparation (1:1–8).
Mark presents Jesus’ public story beginning with a public act: he comes from Nazareth in Galilee and is baptized by John in the Jordan.
