Luke 17:28-30 "And the world will be as it was in the days of Lot. People went about their daily business--eating and drinking, buying and selling, farming and building--until the morning Lot left Sodom. Then fire and burning sulfur rained down from heaven and destroyed them all... Yes, it will be 'business as usual' right up to the day when the Son of Man is revealed.
We can't hope that we are ready for Jesus' return, we have to live our life being ready. We have to go about making Jesus, making God our daily "business as usual" so we won't be surprised, so we won't be left behind.
Is Jesus part of your "business as usual." I know that I need to stay on top of my life so that I keep Jesus an important part of my each of my days, being careful not to get too busy!
