@neologist,
Quote:"All scripture is given by inspiration of God. . . " (2Timothy 3:16)
I think the the two conceptually key words are 'inspiration' and 'God'. Every individual has an idea of who/what they consider 'God' to be and his or her conceptualization of that will inform what 'inspiration' they take from life they see around them. This is and has always been so. The writers of the Old and New Testament are no different in their humanness and tendencies toward individual perception and/or bias than are people of today.
One can learn as much about how not to be and what not to do as they can about what they should strive to be and do by reading the Bible.
And one can look at the world and the people in it and find as much evidence to convince them that God is love, as they can to convince them that that, in fact, can't be true.
