Forbes magazine (http://www.forbes.com/sites/brettnelson/2013/04/03/come-to-jesus-moment-is-the-most-annoying-business-expression-on-earth/) calls it "annoying jargon" and even gives it it's own acronym, CTJM.
Answers.com (http://wiki.answers.com/Q/What_does_come_to_Jesus_moment_mean) defines it as "...based on the "concept" of the moment at which you decide to accept Jesus Christ as your Lord and Savior, but it has a secular meaning. A "come to Jesus moment" refers to a dawning, epiphany or agreement following a disagreement. It refers to when the light bulb comes on and you understand something or make a critical decision.". There's even a whole website devoted to the moments, http://cometojesusmoments.com/.
So, odd as it may seem as a phrase, I believe that we all ought to have CTJMs as often as possible; no disagreement precursors necessary. Some people might even simply call them "aha" moments.
