Luke 2:46 “Now so it was that after three days they found Him in the temple, sitting in the midst of the teachers, both listening to them and asking them questions.”
The temple was apparently the last place they expected to find him. Otherwise they would not have spent three days looking. Evidently, since Jesus was so wise, the Jews in the temple must have assumed he was the son of someone important in Jerusalem, and thus did not ask him who exactly he was.
Heavenly Father, thank You for Christ! He has all of the answers to our questions. We will spend all eternity hearing what He has to say. Your wisdom is limitless! We will praise You for all of Your mighty works. In the Name of the Lord Jesus Christ I pray and praise You, Amen.
