What does Luke 2:46 mean?
Jesus' family left their yearly visit to Jerusalem (Luke 2:41-42) without realizing that He was still in the city (Luke 2:43). The Bible doesn't explain exactly how things were miscommunicated—we only know that Mary and Joseph didn't realize He was still in the city until they arrived at the end of a day's travel (Luke 2:44). It would have taken another day's travel to return to the city, and some time on the third day to locate Jesus. The reference to "after three days" here doesn't mean a complete 72 hours.In contrast to the concern of His family, Jesus is found calmly discussing Scripture with the teachers in the temple (Luke 2:47). At first, Mary seems upset, suggesting that Jesus has done something wrong (Luke 2:48). Jesus' answer and Luke's editorial comment indicate He did not, even if Mary did not entirely understand what was happening (Luke 2:49, 51).
Though Jesus was entirely free from sin (Hebrews 4:15; 1 Peter 2:22), being fully human meant growing and learning (Luke 2:40, 52). As an adult, He seemed fond of asking rhetorical questions (Matthew 21:24; Luke 18:19); yet He would also have posed questions to find out information, as would anyone else (Mark 9:21; John 11:34). The queries of this twelve-year-old clearly impress others, specifically as they reveal Jesus' depth of knowledge (Luke 2:47).
