Commentaries:
On at least three occasions, Jesus directs His disciples to meet Him in Galilee after His resurrection (Matthew 26:32; 28:7, 10; Mark 14:28; 16:7). Galilee is the location of the first fishing miracle of Luke 5, where He called His first disciples: Peter, John, James, and Andrew. Not only does it invite a natural comparison between the two miracles, but it also provides a sense of completion—of coming “full-circle.” Galilee is the disciples' home, and their fishing boats are docked there. Moreover, just as in the first fishing miracle, the Sea of Galilee—also known as Lake Tiberias or Lake of Gennesaret—allowed for an intimate gathering away from the masses while providing a feeling of solace and comfort following their Savior's crucifixion.
