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 creatures, so we have limits.

Only God has no limits (except those he voluntarily imposes on himself). The mantra "no limits" is actually a call to idolatry.

If the biblical writers were writing today they might spell out some things more clearly, given how easily even Christians fall into thinking in ways alien and foreign to the biblical story of God and creation.

To some of us, raised and trained in allowing the Bible to absorb the world (that is, to "see" all of reality through the biblical story), the Bible is quite clear about all really important matters.

Human beings are special, of higher dignity and worth than other animals, because they're created in God's own image and likeness. It's actually true humanism.

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