Lover of Ashes

This song is on my mind today. What is it that allows God to love complete messes? I am not by any means complaining, I just think it's crazy that no matter how much I mess up, He loves me through it all. These lines really stick out to me

My filthy complexion is all that I see
But up from these ashes a beauty will rise
The pride of her father
Though humble in size

These ashes are thankful for a new day everyday.
