Today, under the influences of Eastern religions and philosophies imported into the West, many Christians confuse God's Spirit with our spirit and think our spirit is a spark of the divine, "the God within everyone." That's not how the biblical writers thought about our spirits or souls.

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

The idea of having no limits, either through education or money or possessions or power, is radically alien to everything the Bible assumes and says.

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.

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.

We're creatures, so we have limits.

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.
