- I started using Logos nearly 2 years ago when I started back to school (this time, Bible School). As I am a pastoral and an academic studier of the Word, I have found Logos invaluable for both disciplines. The passage guide tool is among my favorites when preparing a sermon and the Facebook and quick search ability of innumerable references have become the lifeblood of my academic career. This tool, for the lay preacher, the pastor, the evangelist, the scholar, or even just the person who wants to go a little deeper, is an absolute necessity. To say that this tool is a necessity is an understatement...I would go so far as to say that neglecting to utilize Logos for your Bible study purposes is nearly a sin (nearly...only God decides what's a sin and what's not). LOL.
