Flavil was the son of Robert Tooms Hall and Sarah Doliska Mills. He married twice, to Martha Jay King of Tennessee (died 1913) and Bertha Williams (married 1919).
He attended the Nashville Bible School, and began preaching in Trion, Georgia, in 1896.
Hall started submitting articles to the Gospel Advocate early in his career, and 1908–12 worked on the staff of Stanford Chamber’s Christian Word and Work out of New Orleans, Louisiana. In 1913, he began writing for the Christian Leader.
Around 1911, Hall started expanding his evangelistic ministry northward, traveling to the Ohio Valley, and later as far as Canada.
In 1928, Hall moved to Pontiac, Michigan, where he stayed two years until returning to Georgia. In 1931, he moved to Portland, Indiana, and later to Cincinnati, Ohio; Millport, Alabama; and Pine Apple, Alabama (1940–52).
