The phrase I must be “in my Father’s house” in verse 49 actually refers to more than the Temple in Jerusalem. Many translations say “in my Father’s house” but the King James and others also legitimately translate it as “I must be about my Father’s business.” The words “house” or “business” are not in the Greek, but the phrase may be legitimately translated as something like, I must be involved in the things of my Father. So, the word house may be understood as household affairs or business. As we are converted, it is called being born again, or born from above. We are to honor our earthly fathers, but the Father who takes precedence is God our heavenly Father.
