A worldview is a set of presuppositions (or assumptions) which we hold (consciously or subconsciously) about the basic makeup of our world. Another way of saying it is that a worldview is your basic belief system of how the world operates; some people are very conscious that they have a worldview, others are not quite aware of the worldview they possess.
Western, Australian culture has a worldview that it structures, and the worldview also helps structures the culture. In general, Western worldview renders our thinking and senses incapable of understanding spiritual realities, including the spirit world of angels, demons, heaven, hell, etc. This is because our worldview trains us to be materialists and rationalists — we default to believing that the only dynamics that influence us are the natural principles of cause-and-effect, and that if we can’t scientifically measure something, it’s unreliable.
This has resulted in many Western Christians not knowing what to do with the spiritual phenomena that we find abundantly scattered across the Bible. Instead of seeing supernatural work as a reality we can engage in, we have limited it to the role of authenticating Scripture — a role that is no longer needed today with the canonization of Scripture.
Of course, we challenge that limited view of the role of miracles, signs and wonders. Our position at MCChurch is that these supernatural works are crucial and vital to the ministry of the church today — that the primary role of spiritual phenomena (especially works of healing, the supernatural gifts of the Holy Spirit, miracles, signs, and wonders as we see in the Gospels and Acts) is not merely Scripture’s authentication, but the invasion of the Kingdom of Heaven on the earth today. These phenomena are signs that the Kingdom has come upon a person or a place, and that the kingdom of Satan is being pushed back and losing ground.
Romans 12:2 encourages us not to conform to this world, but to be transformed by the renewing of the mind. For Christians to be involved in a supernatural that mirrors the works of Jesus and the Early Church in the Bible, the renewing of our minds in the area of our worldview is crucial. Worldview becomes the foundation upon which we exegete or interpret biblical texts; and if our worldview is biased against the supernatural, we suffer a blindspot that causes us to miss much of what God wants to do in and through us.
