Today's Gospel acclamation, Luke 21.36: Be vigilant at all times and pray that you may have the strength to stand before the Son of Man ~ Jesus said this. That we shall stand before him one day is inevitable. Sins weaken us, so to be vigilant is to be sure that they are taken away by the Lord as soon as possible. Of course, if you are pure enough to receive Holy Communion, you should have the strength to stand before him. Nevertheless, the best preparation is made by seeking union with God. When you attain it, you'd want to go to him in earnest so as to meet your most beloved.
