Knowledge has come to be defined as what can be proven by secular evidence and arguments.

Humanism cannot survive on a purely secular platform.

Only a loving and covenant-making personal God can provide humans with unique dignity, worth, and rights. Blind nature cannot do that. So, for the Christian, "secular humanism" is an oxymoron.

The biblical writers assumed many things about reality that modern, Western people do not assume because we've been conditioned by our cultures to assume otherwise.

The biblical writers didn't need to say everything; they could assume some things. They didn't anticipate a day when even Jews and Christians would fall under influences of non-biblical religions, philosophies, and worldviews, to the extent that is now the case in our pluralistic culture and society.

Too many American (and other) Christians revel in feelings and/or morality and don't care to develop a biblically-shaped Zeitgeist or worldview. The result is folk religion rather than classical, historical Christianity which has always included sound theology.
