Being fully and perfect man, a pre-occupation of Luke, Jesus grew physically. Most significantly, He grew spiritually, emotionally, intellectually and socially.
It would be a sad fact of life if a 30-year old man stayed on the lap of his mom suckling away at her breast. Sadly, many of us do exactly that in the church. Year in and year-out we stay put, afraid to venture out into God's zone of faith and favor.
Rather than be stagnant, impassive or bored in our lives, Christ examplifies for us and calls us to a life of active social engagement, spiritual growth, intellectual exploration, and emotional integrity. By stating to his parents at the age of 12, "Why is it that you were looking for Me? Did you not know that I had to be in My Father's house?" (Luke 2:49), Christ demonstrates to us the imperativeness of clarifying our mission and purpose early in life.
