Father's Business - a Christian perspective
Unbeknownst to his parents, Jesus stayed behind in Jerusalem after the Passover Feast one year. They spent three frantic days looking for him before they found him pontificating and debating with the religious leaders. He told his parents that he was doing his Father's business.
"Father's house" in the Bible: John 14:1-3
Jesus says his father's house has many rooms. He tells us to not be troubled and to trust in God and him for he is going to prepare a place for us in his father's house.
