Tozer compiled many of Christianity's profound mystical voices. In His own word..
"The purpose of this book is to bring together in one convenient volume
some of the best devotional verse the English language affords, and thus
to make available to present day Christians a rich spiritual heritage
which the greater number of them for various reasons do not now enjoy.
For Tozer, these mystics had “been brought by the gospel into intimate fellowship with the Godhead.” Tozer didn't not want these voices to be ignored or forgotten gathered them together “to make available to present-day Christians a rich spiritual heritage which the great number of [us] for various reasons do not now enjoy.”
"This is a book is intended the worshiper rather than for the student.
It has been carefully and lovingly prepared for those God-enamored
persons who, while they feel as deeply as the enraptured poet, yet
lack the gift that would enable them to express their feelings adequately."
The hymns and poems Tozer has compiled are mystical in the sense that they are God-oriented—they begin with God, embrace the worshiping soul and return to God again.
"The word mystic as it occurs in the title of this book refers to that
personal spiritual experience common to the saints of Bible times
and well known to multitudes of persons in the post-Biblical era.
I personal came across this priceless little volume in 1980. while reading Tozer's "The pursuit of God." It was through these pages i became acquainted with the christian mystics. I'm ever grateful to Tozer for the introduction to this deep, rich and often ignored and forgotten stream of the christian tradition. My heart was emblazoned by their passion and i never turned back. The mystics have been constant companions, fellow pilgrims, bell weather voices in my journey toward the Divine.I highly recommend Mystical verse to any post modern pilgrim who hungers for solid food on the journey toward the divine presence.
