When she was 6 months old, she was blinded due to misdiagnosis by quack doctors, which made her unable to appreciate the green mountains and green waters, spring flowers and autumn moon. of beauty. Her grandmother was a very devout Christian. When she was a child, her grandmother would put her on her knees, read God’s words to her, tell her how beautiful the sun was, how beautiful the world was, and how beautiful the world was. She talked about God's creation, so she had God's words and the grace given by God in her little heart. Crosby opened up a new realm from her misfortune, in which she saw Jesus Christ as her helper, friend and savior. Therefore, her pure heart and devout faith enabled her spiritual eyes to appreciate the endless beauty of heaven, and she continued to write beautiful, moving and inspiring poems.
