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.

"Ultimate reality" is the highest, deepest, eternal, unchangeable, source and ground of everything we see, touch, and experience with our five senses. It's that which gives being and meaning to everything finite, mortal, changeable. It's also that toward which we creatures look and live - whether we know it or not - our telos; our goal and purpose.

The Heidelberg Catechism rightly says, for all Christians who allow the Bible to absorb the world for them - who see reality through the biblical story - that the purpose of life is to glorify God - a personal being who is ultimate over us and everything else - and enjoy him forever. This should be clear to all Christians, but many Christians have been influenced to think otherwise even about the Bible because of dabbling in movements such as the New Age Movement or the Gospel of Health and Wealth or even naturalistic humanism.

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 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.

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.
