What does the Bible say about Jesus growing up?

The Bible in Luke 2:39-40 mentions Jesus' early development, indicating that as a child, he grew strong in spirit and was filled with wisdom, with the grace of God upon him. This growth is significant as it affirms Christ's true human nature, illustrating that He developed like any other child, experiencing the same limitations and growth processes we do, yet without sin. This human experience was essential for Him to be our representative and deliverer, embodying the requirements of the law perfectly.
