Mr armughal and redvelvet have given excellent answers to your questions in their posts, however I think Sister most of your questions will also be answered if you read about or listen to the story of Hazrat Rabia Basri Rehmatullah Elahe available also in youtube:
Masha Allah She lived an exemplary life, and her grave is in Jerusalem…
the best example of her devotion to Allah SWT is indicated in one of her prayers :
She prayed:
O God! If I worship You for fear of Hell, burn me in Hell
and if I worship You in hope of Paradise, exclude me from Paradise.
But if I worship You for Your Own sake,
grudge me not Your everlasting Beauty.[6]
