My uncle gave me this verse when I was struggling with a few things. Some things I am still struggling with.
I do however prefer the NIV's use of the word "timidity"
For God did not give us a spirit of fear and timidity, but of power, and love and self-discipline.
I went so far as to look up the definitions...
timidity: showing a lack of courage or confidence
cowardice: lack of bravery
So, yes, I believe the use of cowardice is a bit harsh, but the Bible has never been a book to mince words. And seeing as how I prefer the readability of NSRV, I guess I'll stick with it.
When you start looking at verses from the Bible, it's good to have several different version available to you, and while my uncle has a collection of several different Bible, I only have the NSRV and my daughters have the NIV. However, there are places online where you can find them.
Here's all the versions for 2 Timothy 1:7.
But there are also Commentaries.
I'll continue to learn...
