I was brought up to follow Christ

"The people who sit in darkness have seen a great light." Isaiah and Matthew knew the power of light shining in darkness, but for them, it wasn't the sun. It was the Word of God piercing a world in which power and greed seemed rampant, that Word becoming incarnate in Jesus, calling all to conversion.

I don't think it's an accident that Matthew recalls the words of Isaiah just before he records the call of the disciples. Perhaps light is what Peter, Andrew, James, and John saw when Jesus walked by their boats and called them into new lives as his disciples. It was light that made them drop everything to follow him. Jesus is our light, too, and he's never stopped calling us to follow him.
