I shouldn't stop that passage in mid-sentence, but it captures the essence. It reminds me of Much Afraid in Hannah Hurnard's, "Hinds Feet On High Places."
She is told she must be ready. But when the Chief Shepherd passes by singing, as a clue for Much Afraid to follow, she is trapped in a cabin with her fear-full relatives.
Ten virgins awaited the arrival of the Bridegroom. Five were ready--only half. The others were left behind.
Lot hesitated when angels urged him to hurry; "take your wife and two daughters . . . or you will be swept away when the city is punished (Genesis 19:16)." The angels grasped he and his family by their hands and led them out of danger-- away from God's judgment.
Two women will be grinding grain together; one will be taken and the other left (Luke 17:35).
If the owner had known what time the thief was coming, he would have kept watch and prevented the robbery (Matthew 24:42).
Matthew tells us we don't know when the Son of Man will come.
To me this all means I need to walk consistently, not with Jesus one day and the world the next.
To me, it means that it isn't enough to "get ready." I need to "stay" ready.
