The kingdom of heaven will be like ten maidens who took their lamps and went out to meet the bridegroom. Five of them were foolish and five were wise. The foolish ones, when taking their lamps, brought no oil with them, but the wise brought flasks of oil with their lamps.
Matthew 25:1-3
So Jesus tells a parable about ten bridesmaids. At that time, a bride and groom would get married in one location and then move to the wedding feast or reception, just as we do in our day. However, the bridesmaids in that time had a different job than they do today. They had a definite service of having torches that burned with oil to light the procession so people could see where they were going.
Like the bridesmaids in the parable, God has given us a definite service. We are to let our light shine through the opportunities to serve that God sends our way so that others can see Jesus who is represented by the bridegroom in the story.
Pray for the grace to know the definite service God has given you to serve him today and for the whole of your life.
