The Baptism and Genealogy of Jesus

²¹When all the people were being baptized, Jesus was baptized too. And as he was praying, heaven was opened

²²and the Holy Spirit descended on him in bodily form like a dove. And a voice came from heaven: "You are my Son, whom I love; with you I am well pleased."

Luke 3; 21- 22
