Jesus told us he will come again - a Second Christmas, one might say.
Then he told a story about his second coming. The parable of the 5 wise women and 5 foolish. All ten were waiting for the moment the Bridegroom would arrive after being away on a long journey. Only 5 were prepared and bought extra oil in the house for their lamps. The other 5 women figured they did not know the day or the hour of his arrival, so they just went on living unprepared.
Too busy to daily fire up your lamp with Jesus? What if he came today, right now? Fifty-percent will not be ready to meet Him. Fifty-percent will be invited to the wedding banquet!
