In the book of Esther, God was not mentioned. Not even once. But there are snippets of scenes that mirrored one of the hurtfuk experience of Jesus Christ with the character of Esther.
Esther is one of the most promising woman ever told in the book of Old Testament. But she wouldn’t have been that important without someone backing her up to achieve what she had. Mordecai was faithful to his God and that is why Esther followed his footsteps and the duo made a huge impact in the history of their people up to this generation.
