Christ provided a metaphor for his return in Matthew 24 with a fig tree that begins to leaf and get tender.
No to read too much into the juxtaposition but when you hear Boney M in the shopping centres then you know Christmas approaches. Of course there are other clues.
The word advent means ‘coming’, the expectation of an arriving person or thing. I can mark the hours, days and weeks to the start of my vacation, or the arrival of family members from another city. Or, the ultimate advent, marking the time to the return of Christ.
It occurs to me that looking at Christmas, the first coming of Christ evokes his second. He has come, and will come again.
