Regarding the question which books you should read?
First of all it’s the bible you should read. That is the only book you will ever need.
Then comes the question which Bible version should i read?
If you are english speaking then you should read the king james bible. If you are swedish then you should read the king james bible. Because there is no correct bible available for sale in swedish in roman type. Karl XIIs bible is available online in roman type but its not available in roman type printed on paper.
If you are non english then it might exist a version in your language. The correct version of the bible were published before 1880. For example I think there is a correct version of the bible in farsi and in spanish etc. To find out more about this check the shop of avpublications.com.
Then comes the question which king james bible should i buy?
There are king james bibles that have been changed. For example Broadman Holman Publishers have copyrighted the king james bible text in some of the bibles they sell. Which means they must have done a significant change to the text because you are not allowed to take out a copyright unless there is a substantial change.
Often you can find these bibles in your national internet bookstore. Search on ISBN number. First find the book on the international publishers homepage. Take the isbn number and put it directly into google or into the search field of the national internet bookstore.
Good enough for reading unless you get tired.
Same as above but leather.
Cheap but small text.
Nice large text but too large to take with you.
Complementary since only NT
I also recommend listening to the king james audio bible narrated by Alexander Scourby. Its available for free on youtube.
How often should i read in the bible?
I recommend that you read the new testament of the king james bible for an hour every day. Start the day by an hour of reading in the new testament. Reading the old testament can be done in addition to that hour of reading of the new testament but its optional. Listening to the audio bible can also be done in addition to that but optional.
So do I have the inerrant written word of God now when i have the king james bible?
Its my opinion yes.
