God has a plan for your life: Nothing in the life of a Christian happens by chance. God placed Esther in a royal position for a purpose, not by chance or because of a plan from Mordecai. God uses people for his glory, and even evil can be used to fulfill his plan.
Step out in faith: If you are operating in God plan for your life, then be willing to step out in faith (Hebrews 11:1). Stepping out in faith does not mean you are blindly stepping out in faith into the unknown and putting your life and that of others at risk. Rather, stepping out in faith means you are consciously and confidently choosing to step out in faith because of the trust you have in God.
When I do not know what God’s plan for my life is or I operate outside of His plan, then I am taking risk and assuming full responsibility for the outcome(s). In faith, Esther approached the king without his permission, but she had the permission of God, the King of Kings. Esther's trust in God brought great rewards for her and her people (Proverbs 3:5-7).
God cares for his people: God set a plan to save the Jewish people from their enemies. Mordecai, Esther, and yes the nobles of the Medes-Persians, Queen Vasthi, immoral King Ahasuerus , and wicked and egotistical Haman were all part of God's divine plan.
Position of privilege comes with responsibility: Esther's position of privilege was a call to responsibility. “Great gifts mean great responsibilities; greater gifts, greater responsibilities!” (Luke 12:48 MSG).
Do not get ahead of God: François-Marie Arouet, known by his penname M. de Voltaire was a French Enlightenment writer, philosopher, satirist, and historian. Famous for his wit and his criticism of Christianity (especially of the Roman Catholic Church) and of slavery, Voltaire once wrote, “Everything you say should be true, but not everything true should be said”
Esther didn't tell her people of her kindred because Mordecai had told her not to.
Give God room to move: Esther's choice to require only what was provided for her led to her gaining favor and allowed God to display his supernatural powers in her life.
