Blessings In Using The KJV
For me, the one main blessing in using the King James Version through the years, has been the ease of memorization. Because of it using the King’s English (the Thee’s, Thou’s, verily, peradventure, etc.), it makes for easy memorization: http://www.songsofscripture.com/King-James-Version.html
Another blessing is the great reverence toward God that the KJV text presents. It’s beauty of reverential expression is unequaled: http://www.solagroup.org/articles/historyofthebible/hotb_0015.html
