What is the main summary of A Portrait by Christina Rossetti?

The poem describes a "she" who chooses to give up earthly pleasures and to live with the lowest of the low throughout her life. Instead, she chose to focus on Jesus and God, so that she could go to heaven at the end of her life. The second stanza shows people gathered around her bed as she faces her death. The poem makes the reader feel certain that what she gave up will, in fact, earn her the greater good of going to heaven "with the saints in paradise."
