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.

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.

For Christians ultimate reality is and can only be a personal, sovereign, holy, and loving God. But even some Christians, under extra-biblical and even anti-Christian cultural influences read the Bible as pointing to something not ultimate, such as material wealth, health, happiness, power, etc.

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.

We're created in God's image, but our souls or spirits are not offshoots of God's own Spirit - as New Age teachers would have us believe.

There's nothing easy or simple or even entertaining (in our contemporary American sense of that word) in disciplining our minds to "see" reality through biblical lenses; it takes effort and time. But Christians who don't take that effort and time will inevitably succumb to some of the anti-biblical and anti-Christian messages that bombard us every day through advertising, entertainment, etc.

The Bible portrays God as entering into covenants with people which, when broken, causes him grief and sorrow. The biblical prophet Hosea and God's using him as an illustration of how much Israel's idolatry costs God emotionally points to God's vulnerability. But also the incarnation of God in Jesus Christ who, even as God the Son, suffered for our sins, points to God's vulnerability.
