"Clouds and darkness surround us, yet Heaven is just, and the day of triumph will surely come, when justice and truth will be vindicated"

In this quote, Mary Todd Lincoln is acknowledging the problems and difficulties that we deal with in life, represented by the "clouds and darkness" that surround us. Nevertheless, she also reminds us that regardless of these battles, there is still hope for a simply and reasonable outcome. She thinks that ultimately, justice and reality will prevail and be proven right. This can be viewed as a message of determination and faith, encouraging us to keep the belief that in the end, things will exercise for the better. It acts as a pointer to remain strong and keep fighting for what is right, even in the face of hardship.
