Purim began last night at sundown. Purim celebrates the success of Esther, Mordecai and many other Jews in captivity who overthrew the plot of Haman to kill them all. Esther, after rising to the position of Queen of Persia from being a lowly Jewish exile, found herself in the midst of a genocide plot. But she wasn't sure she should risk revealing her ethnicity to the king. Her uncle Mordecai told her that perhaps God placed her in this situation for "just a time as this."
God tends to place us in all sorts of situations for "just a time as this." It may be at work, or on the bus, or in the grocery check-out line or where ever. We often miss those moments because we're not anticipating God to use us in our everyday situations. But He wants to use us. We just need to keep our eyes and ears open.
