How does Devotions upon Emergent Occasions connect physical illness with spiritual concerns?

In his 1623 work Devotions upon Emergent Occasions, written while recovering from a life-threatening illness, John Donne correlates his physical decline with his spiritual condition.12

The text is structured into 23 devotions, each consisting of a meditation, an expostulation, and a prayer triggered by specific events in his sickness—such as the arrival of a physician or medical treatments. Through these, Donne draws parallels between his bodily suffering and his spiritual state, suggesting that physical illness serves as a mirror for the soul's health.12

This connection reaches a climax when Donne hears the tolling of a passing bell, prompting him to contemplate his own mortality and the unity of all Christians in the mystical body of Christ. By utilizing Metaphysical conceits, such as the famous observation that "No man is an Iland," Donne illustrates how individual suffering is inextricably linked to the broader human and spiritual experience.1
