I have a question I use many translations of the bible the NLT NASB KJV and the CJB why do so many people argue that we just have to stick to one version by using these versions I am able to understand the word more with commentaries and not taking the bible out of context I grew up with the KJV which is my primary but I also like the Nasb I help process it more if that make any sense just the I would put this out there may God bless you all
