As soon as Jesus was baptized, he went up out of the water.  At that moment heaven was opened, and he saw the Spirit of God descending like a dove and lighting on him.  And a voice from heaven said, “this is my Son, whom I love; with him I am well pleased.”

Notice the presence of the Holy Trinity at the baptism of Jesus.  Jesus is present in baptism, The Holy Spirit descending to light on him, and God the Father’s voice: “This is my Son…”  Amazing.
