What and where are Galilee and Bethsaida?
The body of water most often referred to as the "Sea" of Galilee is actually a lake through which the Jordan River flows in northern Israel. "Galilee" (John 1:43) also refers to the region around this body of water, and Bethsaida, which means, "House ('Beth') of fishing" is a fishing village on its north shore.
How do you think Andrew and Philip said what they said in verses John 1:41 and 45?
They were most likely very excited and said those words in raised voices. The Bible records events, including many that are highly emotional, in a dry, matter-of-fact manner. There is no embellishment or hyperbole, and this will become increasingly apparent as we progress through the rest of this Bible study.
What do you think of Nathanael's first reaction?
It was based on his preconceived ideas, his 'prejudices'.
How does Philip respond?
He told Nathanael to "come and see" (John 1:46) Jesus for himself.
How applicable is his advice for people today?
The vast majority of people who don't believe in Jesus base their beliefs, or the lack thereof, also on preconceived ideas. They may have heard people who claim to know the Bible talk about Jesus but they've never considered the evidence - the Bible - for themselves. They may have heard some movie critics, but they've never watched the movie for themselves. To them, Philip's invitation to "come and see" Jesus - the World of God - for themselves applies as much today as to Nathanael two thousand years ago.
