Mordecai and Esther had different roles to play but were united in their goal. Similarly we are many but one body and we each have a part to play. In the light of this we should stand firm, putting on the full armour of God.
Susan reminds us of how God defeats the enemy in the places of despair and loss of hope; challenges us to identify those areas of our lives where despair and resignation have set in; and encourages us with the good news that the Lord, who is our shepherd, longs to shepherd our souls through every disappointment in life and to bring restoration. He restores our souls.
