There is a special reason for why we are all created. This passage is very powerful. I am not sure if you know who Esther was in the Bible but she was a Jewish Queen, very interesting story (Link above).
God wants to use us for his Glory, which is much more fulfilling than the Glory for ourselves, it provides you with a joy and presence so strong it could bring you to tears. Ultimate happiness. This scripture is saying that God will deliver the Jews with or without her. If she would deny God, he would use someone else. What a wonderful blessing when God wants to use us.
“For if you remain silent at this time, relief and deliverance for the Jews will arise from another place, but you and your father’s family will perish. And who knows but that you have come to your royal position for such a time as this?”
