"And the king said unto Esther the queen, The Jews have slain and destroyed five hundred men in Shushan the palace, and the ten sons of Haman; what have they done in the rest of the king's provinces? now what is thy petition? and it shall be granted thee: or what is thy request further? and it shall be done" - Esther 9:12
God has promised to provide us. Look at how He has done so for Esther. He's softened the heart of a king who has proven to be harsh with his former queen. King Ahasuersus loves Esther greatly and allowed her to write the decree that would save her people.
It's amazing to see how God can change a heart. I am thinking of someone to whom I've been very close that has come close to serving the Lord, but ultimately chose to reject Him. I'm so thankful to the Lord that He provides us with examples of people like Ahasuerus. When we see his proud heart at the beginning of the book of Esther we might think that he's not capable of the kindness that he has shown to Esther, but nothing is to difficult for God. If you are praying that the Lord will change the heart of someone that you love, do not be discouraged. God is powerful enough to change any heart! Keep praying!
