In each of the other 3 Gospel Accounts (Matthew, Luke and John), Jesus is introduced either by His birth (Matthew and Luke) or by His Creation (John). In Mark, He is introduced in today's Text.
One day Jesus came from Nazareth in Galilee, and John baptized him in the Jordan River. As Jesus came up out of the water, he saw the heavens splitting apart and the Holy Spirit descending on him like a dove. And a voice from heaven said, “You are my dearly loved Son, and you bring me great joy.” (Mark 1:9-11 NLT)
The story of Jesus' Baptism is also given in Matthew 3:13-17 and in Luke 3:21-23.
Luke's account gives His age of 'about 30 years old'. It is interesting that at the age of 30 most Jewish father's would proclaim their eldest son as 'heir' to all that is theirs. This is also the age a Levite could begin Temple Service.
Chronologically, the last time Jesus was mentioned in the Gospels was when He was in the temple as a boy (Matt 2). Nazareth (Jesus' home) was a town of 500 where Jesus had been a carpenter. That had been what others would say was Jesus' Identity...a carpenter, the son of a carpenter or the son of Joseph.
Each of us are known by something. We are known by our jobs, our family, our attitude, our accomplishments, etc. Our identity (in the minds of others) is made up of many parts of who they say we are. We typically find a lot of value in being 'identified' in certain ways. Men typically enjoy being identified with a successful career. Ladies can sometimes find value in being identified as a super-mom. Good careers and good parenting are both good things but there is a danger in letting your identity come from those things. Notice that each of those things are quite temporary. They can change. If all of your value is wrapped into being an X (fill in your job here) then what happens to your heart when that changes? It could be devastating.
Our true identity (who we really are at our foundation) best be linked to something that is not temporary. We best be identified with something (and someone) who will not change and will not leave. There is only one identity that fits that description. It is the identity of the follower of Jesus. It is the identity of a child of God.
Our text shows a time when Jesus' was identified to everyone that was paying attention. No longer was he just the Carpenter from Nazareth or the Son of Joseph. He was dearly loved Son of God.
Where do you find your identity and your value?
