What does Luke 8:24 mean?
Jesus and the disciples are in a boat in the middle of the Sea of Galilee. It's night, and a violent storm has sprung up. The disciples are afraid of dying, but Jesus is asleep.The repeat of "Master" indicates how anxious they are. This word, however, is different in each Gospel. Matthew uses a single "Lord," and Mark uses one "Teacher." This demonstrates the concept of ipsissima vox: that the words recorded are the "very voice" of the event, not necessarily a transcription of exact words. The effect is the same in that the disciples are going to Jesus as their authority figure to rescue them. Then again, it may be that in that moment Matthew used "Lord," Peter—Mark's source—used "Teacher," and whoever told the story to Luke used "Master." It's reasonable to think not everyone in the boat used the same word when they cried out to Jesus. In any case, the three words refer to an authority, but even "Lord" does not mean they understood Jesus to be the Messiah and Son of God.
Greco-Roman mythology claimed certain rulers had power over the sea. However, in their view, that power was not expressed so casually as controlling the waters with just a brief spoken phrase. The sea is a symbol of chaos: from a human perspective, it is the ultimate in uncontrollable and unpredictable forces. That Jesus' mere words calmed the storms would have been just as astounding to readers of this Gospel as it was to the disciples who witnessed it.
Scholars argue over whether Jesus confronts the storm as He does demons. "Rebuke" could be seen as a response to a natural evil like illness or as a response to a supernatural enemy. Either way, Jesus responds to the storm as an evil that is hindering His purposes of crossing the lake. But He also reveals Himself as the Creator who brought order to the waters (Genesis 1:1–10). "Rebuke" refers to strong disapproval, and can imply a more aggressive or strident tone. Jesus told the wind and waves, "Peace! Be still!" (Mark 4:39). "Raging," here, suggests the waves kept coming, one after another.
When Jesus speaks, the wind and waves cease and the water becomes flat and motionless. The waves that were coming in succession simply stop. As with many of Jesus' miracles, "He has done all things well" (Mark 7:37).
