Well, a knoweldge man or 'wise' man should know that, but what we get with people who talks against it, talks of more of points with acquired knowledge and some other points that are not in the bible!, like a teaching of some sort.
If God gives you wisdom for you in a particular situation in you life, personal matters or something you could do etc, then that is wisdom from God, that you could not get with the bible.
I'd say we got it/get it "because of the Bible", but that may just be me...
I think "everything we have now, or can even get now", is because of the Bible and what Jesus and his apostles, and His servants through the ages, all the way to today, did for us/does for us, because of and starting with Jesus Christ, and what (all) He did for us shown in and by the Bible, ect...
Where would the world be today with what Jesus (His apostles/servants, ect) did, do today, ect, and/or because of and by the Bible...?
I shudder to think what the world would be like today, and where the world would have gone (the course it would have took) (or will take in the future without it and God, ect) (If certain ones succeed in that agenda to eliminate it/Him/Them) Anyway, I shudder to think what the world would be like today, and where the world would have gone without Jesus Christ and God and the Bible or Scriptures...
We owe it and Him/Them (God) not only our lives, but "everything else", we owe it all to Him/Them and the Scriptures being recorded and or written (down) for us...
God Bless!
