In the name of God, Father, Son and Holy Spirit, Amen.
The gospels tell us almost nothing about the training or education of Jesus. There is a little about his childhood in Luke, but soon we are hearing about the preaching of John the Baptist, in the passage we read today. John was a relative of Jesus, a prophet who preached that the Messiah- the one who would save God’s people- was about to appear. John called people to change their lives, to get ready for God’s saviour to appear among them. Crowds of people went down to the River Jordan to hear John’s preaching. And he would challenge them to respond by being baptised. John would immerse people in the waters of the River Jordan, to symbolise that they had died to their previous life- drowned it, if you like. They rose from the water into a new life, with their sins washed away, as water washes away dirt.
Eventually, Jesus himself appeared, and was baptised by John in the river as well- and you can see a picture of it on the front of our order of service. Jesus’ baptism marks the point when Jesus passed from being a purely private figure to becoming a public preacher. This is a day he for which he would have been preparing for years. It is Jesus’ graduation day, his passing out parade.
