Joseph naturally dreads his marriage to the young maiden, Mary since she is pregnant; and that, out of wedlock. Joseph ought to report Mary, have her stoned to death per the Law of Moses. Yet, he listens to the angel of the Lord who comes to him in his sleep.
The angel of the Lord says something truly extraordinary, that Jesus “shall make His people safe from their sins.” The angel doesn’t say, “Jesus shall make His people free from sin.” Rather, the angel verifies that Jesus is to make His own people “safe from their sins.”
“But while he thinks these things, lo! the angel of the Lord appears to him in sleep, and says, Joseph, the son of David, do not thou dread to take Mary, thy wife; for that thing that is born in her is of the Holy Ghost. And she shall bear a son, and thou shalt call his name Jesus; for he shall make his people safe from their sins.”
That we sin is a fundamental truth in the Christian life. That Jesus died for our sins is also a fundamental truth of the Christian life. Jesus nails the Law to the tree, and washes away the wage of death with His blood.
The longing in His human heart perhaps is enormous; for the boy Jesus leaves His earthly parents and finds His Father’s house at the conclusion of the Feast of the Passover. “The boy Jesus stays behind in Jerusalem. His parents do not know it, but supposing Him to be in the group they go a day’s journey, but then begin to search for Him among their relatives and acquaintances.” (Luke 2:43-44)
Joseph and Mary spend three days searching “in great distress” for their son, Jesus. (Luke 2:48) Oddly enough, they fail to look in the most obvious place — the temple. They look “in the group,” “among their relatives,” and even among their “acquaintances;” but they fail to look “in My Father’s house” as Jesus says when they find Him. (Luke 2:49) Of course, Jesus is there “in the temple, sitting among the teachers, listening to them and asking them questions.” (Luke 2:46) Logically, if not “in the group” or “among relatives and acquaintances” where else would He be? Joseph and Mary ought to know better.
Yet, Jesus — despite being twelve and about His Father’s business — “goes down with [His parents] and comes to Nazareth and is submissive to them.” (Luke 2:51) And His mother Mary, with her firsthand knowledge of God, the Holy Spirit, “treasures all these things in her heart.” (Luke 2:51)
