Who was Jesus? The second chapter of Matthew's Gospel ends with Jesus growing up in Nazareth. Nazareth was known as a town from which nothing good could come. In fact, the word 'Nazarene' may actually have been a nickname or slang meaning for something that was insignificant.
So what does Luke 3:23 tell us about who Jesus was/is. The phrase 'so it was thought' reveals that to human eyes, Jesus was the son of an unimportant carpenter from insignificant Nazareth. His human resume was not one to boast in. Yet, in reality, Jesus was the beloved Son of God, in whom the fullness of God was pleased to dwell.
"This is my Son, whom I love, the one in whom I am well pleased." Matthew 3:17
"For God was pleased to have all his fullness dwell in him" Colossians 1:19
In God's sight, Jesus was the Beloved Son. This was His true identity. In the same way, our human resume is nothing to boast about. There is nothing great about us. Our identity in ourselves is rather insignificant in the big picture. Yet, when we are in Christ, the reality of our identity is radically different. In God's sight, we are beloved children with whom He is well pleased. This is our true identity.
