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.
Roger E. Olson"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.
Roger E. OlsonThe 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.
Roger E. OlsonToday we cannot assume people, even all Christians, understand the Bible's implicit, underlying view of reality. We have to dig it out and show it to people, including Christians, and ask them to "see reality as this" rather than "as that" - where "that" refers to any number of unbiblical ideas about reality.
