Jonathan Edwards (October 5, 1703 – March 22, 1758) was an American revivalist preacher, philosopher and Congregationalist theologian. His influence on Joseph Smith is being examined by modern scholars in connection with the revival of interest in Jonathan Edwards and the study of intertextuality between the Book of Mormon and other texts, including the Bible and the work of Christian authors.
Jonathan Edwards was associated with Calvinist ideas, but he explained that "I utterly disclaim a dependence on Calvin, or believing the doctrines which I hold, because he believed and taught them; and cannot justly be charged with believing in everything just as he taught."
Readers of the Book of Mormon have long noticed long quotations from the KJV, including several chapters from Isaiah, Matthew, and Malachi. Many other biblical passages are quoted or paraphrased in the text. Some biblical passages are "blended" or combined into Book of Mormon verses. (See the page on blending.)
Scholars have simply assumed that these connections are directly from the KJV due to Joseph Smith's familiarity with the Bible. (Joseph explained that from age 12 onward, he was "searching the scriptures." https://www.josephsmithpapers.org/paper-summary/history-circa-summer-1832/2
However, recent discoveries suggest that much of the biblical language may have come not directly from the Bible, but through Christian authors who themselves blended and paraphrased biblical passages. These discoveries grew out of research that shows that much (probably most) of the non-biblical language in the Book of Mormon, Doctrine and Covenants, and Pearl of Great Price can be found in the works of Jonathan Edwards.
An 8-volume set of Edwards' works was on sale in the Palmyra book store starting at least in 1818, when it was advertised in the local newspaper. When we compare Edwards' writings to the language of the latter-day scriptures, we see many similarities in language and themes.
For example, the Book of Mormon uses the non-biblical terms "type" and "types" to explain how one event anticipates or helps explain another. "But this much I tell you, what you do with me, after this, shall be as a type and a shadow of things which are to come." (Mosiah 13:10)
"But notwithstanding the law of Moses, they did look forward to the coming of Christ, considering that the law of Moses was a type of his coming, and believing that they must keep those outward performances until the time that he should be revealed unto them." (Alma 25:15)
Jonathan Edwards wrote about numerous types (and shadows) in the same way. See a brief discussion here.
There are hundreds of non-biblical terms and phrases in the Book of Mormon that appear in the works of Jonathan Edwards. For background, see the book Infinite Goodness: Joseph Smith, Jonathan Edwards, and the Book of Mormon.
Joseph Smith's personal writings also exhibit the likely influence of Edwards. For example, see this annotated version of Joseph's Oct. 1829 letter to Oliver Cowdery.
In addition to intertextuality, the influence of Edwards is apparent in the themes of Edwards' work. For example, Edwards often wrote about the glory of the Church in the latter days.
Edwards final words summed up his life's work: "Trust in God, and ye need not fear."

Probably the most popular book Edwards wrote was his Life of David Brainerd, a missionary to the Indians. The book is based on Brainerd's own journal. Brainerd stayed at Edwards' home, where he died.
The Palmyra bookstore did not list the Brainerd book for sale, but the book was published in several editions and became a standard reference for Christian missionaries. According to wikipedia, "The work was a major influence on the domestic and foreign missionary movement of the eighteenth and nineteenth centuries, and has been the most frequently reprinted book by Edwards."
