"Praise for the Fountain Opened", commonly known by its first line, "There is a fountain filled with blood," is a hymn written by William Cowper.

It was one of the first hymns he wrote after his first major bout of depression.

There is a fountain filled with blood Drawn from Immanuel's veins; And sinners, plunged beneath that flood, Lose all their guilty stains: Lose all their guilty stains, Lose all their guilty stains; And sinners, plunged beneath that flood, Lose all their guilty stains.

Dear dying Lamb, Thy precious blood Shall never lose its pow'r, Till all the ransomed Church of God Be saved, to sin no more: Be saved, to sin no more, Be saved, to sin no more; Till all the ransomed Church of God Be saved to sin no more.

When this poor lisping, stamm'ring tongue Lies silent in the grave, Then in a nobler, sweeter song I'll sing Thy pow'r to save: I'll sing Thy pow'r to save, I'll sing Thy pow'r to save; Then in a nobler, sweeter song I'll sing Thy pow'r to save.
