Joseph Hart (1712–1768) was a prominent 18th-century London minister and one of the most significant hymn writers within the Calvinistic Nonconformist tradition. His early life is somewhat obscured by a lack of records, though it is known that he possessed a solid classical education and spent several years as a teacher of learned languages. According to his own published spiritual autobiography, his early years were marked by a turbulent mixture of moral laxity and profound religious anxiety. It was not until Whitsuntide in 1757, after attending a service at the Moravian Chapel in Fetter Lane, London, that he experienced a definitive and permanent religious conversion.

This conversion sparked an intense period of creative activity. Between 1757 and 1759, Hart composed many of his most earnest and impassioned hymns, which were published as Hymns Composed on Various Subjects (1759). In the same year, he was appointed the minister of the Independent Chapel in Jewin Street, London, where he served until his death. His hymns are noted for their deep experiential quality, often focusing on the gravity of sin, the necessity of repentance, and a fervent, almost visceral love for the Redeemer. His work quickly gained popularity among Independent and Baptist congregations who shared his robust Calvinistic theology.

Hart’s most famous contribution to English hymnody is arguably "Come, ye sinners, poor and wretched," a powerful invitation hymn that remains a staple in many evangelical traditions. Other widely recognized works include the prayerful "Come, Holy Spirit, come" and the celebratory "This God is the God we adore." His writing style was distinct for its lack of sentimentality; instead, he used a direct and often stark language to describe the spiritual journey. For example, in hymns like "Jesus, while He dwelt below," he provided an exhaustive, multi-stanza meditation on the sufferings in Gethsemane, which later editors often had to break into shorter segments for congregational use.

Hart continued to expand his hymnal with a Supplement in 1762 and an Appendix in 1765, ultimately leaving behind a collection that touched on every aspect of the Christian life, from baptism and communion to public fasts and burials. He died in May 1768, and such was his influence that his funeral at Bunhill Fields was reportedly attended by twenty thousand people. Though the usage of some of his more specialized hymns has faded, his primary works continue to be valued for their theological depth and their vivid portrayal of the "Experience" of faith that Hart so famously championed in his own life.
