These are God's words spoken of Jesus, both at his Baptism and his transfiguration, where momentarily he was displayed before his disciples with his glory. These two events that serve as bookends to Jesus' ministry are marked with words from the Father. Mark, as he opens his Gospel, doesn't leave us wondering who this Jesus is, but in the opening lines focuses our attention on the reality that Jesus isn't just another prophet, civic leader, or social change agent; he is in fact the Son of God. See how these events have a lasting impact on us even today!
