John Calvin published 22 volumes of commentaries on the Bible and Martin Lloyd-Jones published 9 volumes on Romans alone. What if you could remove all of the non-essential language, antiquated stories, and strip all of that knowledge down to some bite-sized, transportable truths? There is certainly room for argument against such condensation of historic works, but we have to realize that we live in a society inundated with more information in a day than Calvin consumed in a year.
In other words, the ability to be succinct and concise is worth gold when communicating truth in today’s culture. And Twitter helps. The ability to write volumes of words is impressive, but possibly not as impressive as the ability to take a deep and complex theological truth or spiritual application and package it in 140 characters or less.
