"Mordecai the Jew was second in rank to King Xerxes, preeminent among the Jews, and held in high esteem by his many fellow Jews, because he worked for the good of his people and spoke up for the welfare of all the Jews." NIV translation
This humble servant was elevated to the number two position in the kingdom because of his love for his fellow man. Jesus told us (in John 13:36) that this is also how we, as Christians, will be known to be His disciples. We, like Mordecai, can expect God to elevate our stature if we are humbly serving Him. It may be in the world today; it may be in the future millennial reign or it may be both.
