(v. 1-20) Esther chosen queen.
(Est 2:21-23) Mordecai discovers a plot against the king.
We see to what absurd practices those came, who were destitute of Divine revelation, and what need there was of the gospel of Christ, to purify men from the lusts of the flesh, and to bring them back to the original institution of marriage. Esther was preferred as queen. Those who suggest that Esther committed sin to come at this dignity, do not consider the custom of those times and countries. Every one that the king took was married to him, and was his wife, though of a lower rank. But how low is human nature sunk, when such as these are the leading pursuits and highest worldly happiness of men! Disappointment and vexation must follow; and he most wisely consults his enjoyment, even in this present life, who most exactly obeys the precepts of the Divine law. But let us turn to consider the wise and merciful providence of God, carrying on his deep but holy designs in the midst of all this. And let no change in our condition be a pretext for forgetting our duties to parents, or the friends who have stood in their place.
Good subjects must not conceal any bad design they know of against the prince, or the public peace. Mordecai was not rewarded at the time, but a remembrance was written. Thus, with respect to those who serve Christ, though their recompence is not till the resurrection of the just, yet an account is kept of their work of faith and labour of love, which God is not unrighteous to forget. The servant of God must be faithful to every trust, and watchful for those who employ him. If he appear to be neglected now, he will be remembered hereafter. None of our actions can be forgotten; even our most secret thoughts are written in lasting registers, Rev 20:12.
