42 Lk 2.40 Jesus grew

Luke 2:40 (ESV)

40And the child grew and became strong, filled with wisdom. And the favor of God was upon him.

Consider John MacArthur's commentary on Luke 2.40: “Luke’s primary emphasis is on Jesus’ spiritual development, as He matured in wisdom until, as the Greek text literally reads, He was “filled with wisdom,” the profound wisdom of the mind of God. Jesus did not possess all of that knowledge as an infant, toddler, or young child. But by the time He was twelve, the fullness of divine wisdom had come to fruition in His mind. A feature of Christ’s incarnation was that He relinquished control of His use of His divine prerogatives to the Holy Spirit, who mediated between His deity and His humanity. By the time He reached twelve, the Spirit had disclosed the understanding of His identity and mission.”
