A complete 1583 edition of the Geneva Bible is on Bibles-Online.net. However, this site uses Adobe Flash, which does not work with iPhones and iPads. Moreover, newer versions of Chrome automatically block Adobe Flash, although you can unblock it. Also, Adobe will stop supporting Flash at the end of 2020. Bibles-Online.net says, “we are working toward migrating the website to another software platform.” The Story of the Bible will monitor this after the end of 2020.
The text of the 1599 edition of the Geneva Bible is available on Bible Gateway.
The introduction to Ephesians ("The Argument") demonstrates the Calvinist theology of the Geneva Bible: Paul "assureth [the Galatians] of salvation, because they were thereunto predestinate[d] by the free election of God, before they were born and sealed up to this eternal life by the holy Ghost."
