1. Twelve-year-old Jesus at the temple (41-47)
Jesus grew as a good, ordinary Jewish boy, attending Passover annually. When he was twelve, they lost track of him on the way home. After three days they found him listening and asking questions among the temple teachers. What did Jesus eat, and where did he stay? Clearly, he wasn't worried about being "lost." He was drawn to the things of God from a young age.
2. "I had to be in my Father's house" (48-52)
Mary asked Jesus why he treated them like this and made them so anxious and worried. Boy Jesus said, "I had to be in my Father's house" (or, "about my Father's business"). Boy Jesus knew he must be near his Father God: in his house, doing his work. Jesus kept growing in wisdom, stature and in favor with God and man.
