“Now His parents went to Jerusalem every year at the feast of the passover. And when He was twelve years old, they went up to Jerusalem after the custom of the feast. And when they had fulfilled the days, as they returned, the Child Jesus tarried behind in Jerusalem; and Joseph and His mother knew not of it. But they, supposing Him to have been in the company, went a day’s journey; and they sought Him among their kinsfolk and acquaintance. And when they found Him not, they turned back again to Jerusalem, seeking Him. And it came to pass, that after three days they found Him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions. And all that heard Him were astonished at His understanding and answers. And when they saw Him, they were amazed: and His mother said unto Him, ‘Son, why hast Thou thus dealt with us? Behold, Thy father and I have sought Thee sorrowing.’ And He said unto them,
‘How is it that ye sought Me? Wist ye not that I must be about My Father’s business?’
And they understood not the saying which He spake unto them. And He went down with them, and came to Nazareth, and was subject unto them: but His mother kept all these sayings in her heart. And Jesus increased in wisdom and stature, and in favour with God and man.” Luke 2:41-52 (KJB)

At the age of twelve Jesus had more knowledge and understanding than the wisest of the scholars of that time. They were awed by this boy who was asking questions and listening to their answers.

He said to His mother and to Joseph that He must be about His Father’s business. Just what is the Father’s business. Jesus would say when His ministry began,

“For the Son of Man is come to seek and to save that which was lost.” (Luke 19:10).

He would also say,

“This is the work of God, that ye believe on Him whom He hath sent.” (John 6:29).

It should be quite clear to all that the reason for Jesus coming the first time was to redeem a people to Himself; to redeem us from our sins by His death on the cross, His burial and bodily resurrection. That is the business Jesus was and is still in.

Call on His name. Believe Him and be saved for all eternity.
