Advent is all about waiting--waiting in joyful expectation for the coming of Christ.
Historically, Jesus Christ already came in the flesh 2000 years ago when he was born in Bethlehem. But there are two other comings: his coming in glory at the end of the world, and his coming by grace into our hearts.
Although anything is possible, Jesus' second coming probably won't be during our lifetime. Here and now, though, Jesus comes into our hearts again and again through grace. Advent is all about opening our hearts to grace, letting the Lord lead us. Advent is such a short liturgical season that it goes by very fast, and we can come to the end of it before we know it. What is the Lord saying to you this Advent?
