She writes to God, because she has no one else to write to.
She feels that what happened to her is so terrible that she can only talk about it to someone she feels loves her.
The Color Purple, by Alice Walker, is a very intense book to read.
By intense, it is a book touching very difficult and hard aspects of life of a poor, black oppressed woman in the early twentieth century.
Celie was able to survive physically and spiritually, and is able to mature into a full, modern twentieth century woman.
In The Color Purple, Alice Walker is able to illustrate the abuse, neglect, and oppression a black woman had to go through in the early twentieth century, but she also illustrate how a woman must fight back to regain the self esteem and confidence lost way back in the early adolescent years.
Walker does social criticism in her novel, mostly criticizing the way black women were treated in the early twentieth century.
Walker uses the life experiences of Celie to illustrate her social criticism.
The Color Purple is a story about growth, endurance, and fight, all nurtured by love.
