Today is the first day of Advent. For many this means absolutely nothing. In our American consumeristic culture, it marks the beginning of holiday shopping deals, a season long of special coffees, and making travel plans to visit family.
A youtuber, Maple Anglican, provides a nice overview of what advent is.
Advent actually marks the beginning of the Christian calendar. Advent is a Latin term that literally means "coming". Christians kick off the year preparing our hearts for the second coming of the Christ. You see Christ came the first time to reveal Himself and ransom people for God. His second coming will bring judgement and separation of the sheep and goats. To some it will be met with joy. To others it will be a time of great sorrow and regret.
This season of Advent reminds me of the story Jesus told of the ten virgins in Matthew 25.
