Scriven wrote this hymn in 1857 in Canada to console his ill mother, left behind in Ireland. As he kept the poem secret, he didn't got credits until after its first publication in Ira D. Sankey's Gospel Hymns Number One collection. During World War I, Converse's tune was linked to the words When This Bloody War Is Over.
