Perhaps we do not reflect on Our Lord's Second Coming enough. I saw Jews pleading at this wall for the first coming of the Messiah. At times I get the impression that people are not too excited about Our Lord returning.
People are busy with things to do, planes to catch, etc.
But Sacred Scripture reminds us not to be caught off guard when the day of the Lord comes. And as it was in the days of Noah, even so will be the coming of the Son of Man. There are many reasons. This Second Coming is the fullness of the reign of God. Since Pentecost, the Holy Spirit has been at work bringing about this kingdom.
