Final answer:
The author is describing Mordecai as a virtuous figure who, despite his grace and good works, struggles with personal temptations due to his human nature, which is flawed like any other man's.
Step-by-step explanation:
The author suggests that Mordecai, despite seeking the welfare of his people and being a symbol of peace and grace, battles with personal temptations. The reference to 'an earthen vessel' implies that Mordecai, like all humans, is fragile and flawed, susceptible to original sin and the corruption of his nature.
The phrase 'grace enough for many men' denotes that although Mordecai is a man of virtue beneficial to others, he may still find himself lacking in his battle against personal vices and temptations. The contrast between his outward grace and inward struggle highlights the complex nature of character and morality.
