Why does God permit sin to rule?

Although sin rules in the human race, and God permits this to a certain degree, still, all your actions and omissions―

All your dealings and their results are in His Almighty Hand―

Everywhere, His angels are fulfilling their office as His messengers, for the good of human race [Humanitas]. 

And when you encounter the great enigmas of the divine government of the world or duobts concerning his ominpotence and the universality of his loving purposes beset you, remember that you are far more insignificant and deficient in understanding with respect to the Almighty than your child is compared with yourself. 

His ways are wonderful, but they are also holy and good.

And nothing wears so different an aspect when looked at from heaven as human prosperity and adversity.

REMEMBER THAT!
