When the days of their purification according to the law of Moses were finished, they brought Him up to Jerusalem to present Him to the Lord. -- Luke 2:22
Each of the steps Mary and Joseph took after Christ's birth was typical of devout Jewish parents. What made it atypical is that their infant would ultimately fulfill the prophetic representation of each of these rituals.
When Jewish parent presented their firstborn son to the Lord, they were symbolizing the act of giving him up by saying, "He is Yours and we give him back to You." Then they should immediately redeem him or, in effect, buy him back with their offerings.
How interesting, though, that the New Testament tells us Christ came to fulfill for us the very rite Mary and Joseph observed as they presented the Christ child to the Lord.
The Word made flesh first entered the temple wrapped in a baby blanket. His earthly parents lifted Him to His Father and, in essence, purchased Him from Heaven -- for awhile -- for a lost world.
One day that baby would buy them from earth for the glory of heaven. Wow.
In Him we have redemption through His blood, the forgiveness of our trespasses, according to the riches of His grace. - Ephesians 1:7
