What does Luke 21:36 mean?
This completes Jesus' warnings about the hardships His followers and the world will experience between the time of His ascension and His second coming. The disciples will face betrayal and persecution (Luke 21:12–17). The Jews will watch as the Romans destroy Jerusalem and dismantle the temple (Luke 21:20–24). Before Jesus' return, the heavens and earth will inflict supernatural violence on the people (Luke 21:25–26). Through it all, the whole world will deal with false saviors, war, and natural disasters (Luke 21:8–11).While we wait, especially as the time of His return nears, we need to reject the escapism and hedonism of partying and drunkenness. We need to put the concerns of our earthly lives into proper perspective. When we meet Jesus, whether after death or at His arrival to claim His kingdom, will we be able to stand? Will He greet us saying, "Well done, good and faithful servant" (Matthew 25:23)? Will we enter into His rest as He rules for a thousand years (Revelation 20:4–6)? Or are we among those who have rejected Him and will tremble in horror as they are banished to eternal torment by our Judge (Revelation 20:11–15; John 3:16–18, 36)?
We can't be prepared by sheer force of will. Peter tried and failed (Luke 22:31–34, 54–62). We need the strength of the Holy Spirit, so we must pray. Only through the Holy Spirit can we stand firm against false teachers, betrayal, and physical dangers.
These warnings are especially important as Jesus' earthly ministry moves closer and closer to the crucifixion (Luke 19:28—21:38). The religious leaders and Jews have all the evidence they need to determine that Jesus is the Messiah. They will reject Him, arrest Him, and kill Him (Luke 22—23). The disciples will flee in fear. But then, Jesus will rise again. He will ascend into heaven. The Holy Spirit will come to His followers, and the disciples will find the courage they need to stand (Acts 1—2).
"Son of Man" has two facets. In Daniel 7:13–14, the Ancient of Days gives the Son of Man dominion over the world. This will happen at Jesus' return. But the phrase also points out that Jesus is wholly human as well as wholly God (Philippians 2:6–7).
