I’m sure that ridiculous assertion makes you two feel good. There certainly is no history of the English in the Bible, or instructions on Chemistry. However, for all Christian purposes, it is complete:
2Ti 3:16-17 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: (17) That the man of God may be perfect, throughly furnished unto all good works.
If it is capable of making the “man of God... perfect, thouroughly furnished unto all good works,” it doesn’t sound like there is anything else we need, unless there is some level beyond perfect.
Gee, I wonder how the Apostles and first Christians survived without that Bible?
Um..one other thing...where does the Bible state that it contains the COMPLETE teachings and/or that we need nothing else?
