Though God's name is never mentioned, the Book of Esther is filled with examples of God at work behind the scenes for the benefit of His beloved children.
Here we see that the author chose a fascinating literary choice - never once is God mentioned in the entire Book. This behind-the-scenes take of God at work is brilliantly displayed throughout Esther's chapters through "coincidences" and "happen chances" that help to save the Jews from Haman's wicked plot to destroy them.
Even today Jewish people celebrate Purim each year by reading Esther, enjoying fun traditions, and giving gifts as described in Esther Chapter 9:20-32. Christians, too, can benefit from reading Esther as it reminds us that even though it appears God is absent, He is still at work in our lives and will not abandon His promises while we are living in a murky and ambiguous world.
