If you can financially manage to secure this set of resources, you will never regret it. Find a way. The depth and versatility of Logos 9 Diamond are nearly impossible to describe, even marginally. I am repeatedly amazed by the vast wealth of spiritual instruction now available on my computers and my phone—none of which devices weigh the least bit more, of course, though the weighty materials they now contain are massively enlightening and influential to anyone whom I'm privileged to teach. I had been compelled to study more and more, becoming more prolific and more hungry, with my Logos 9 Gold. Now, I am exponentially more productive—and absolutely ravenous for the meat of God's word. Thanks to all these authors represented. And thanks to Logos and Faithlife for making these resources available in such a remarkable form. May God bless us all.
