Everyone has a worldview, whether or not they are fully aware of it. A worldview can be defined as the lens through which we view everything that exists. It represents the fundamental presuppositions one has about the universe. It reveals how one answers the questions about who and what we are, where we came from, why we’re here, where we are headed, the meaning and purpose of this life, the existence and nature of the afterlife, etc.
It is nothing less than the orientation of a person’s thoughts and life. As a rule, people don’t mind if you are Christian as long as it doesn’t make them uncomfortable. Many people in our culture like a Christianity that allows them to fit in with contradictory worldviews. These opposing worldviews include naturalism (i.e. there is no God, people are only highly evolved animals, the universe is a closed system), postmodernism (i.e. there is no objective truth or moral standards, reality is what you want it to be), pluralism (i.e. all religious options are equally valid, there are many legitimate paths to salvation), and, perhaps the most common in our southern Minnesota culture, moralistic therapeutic deism (i.e. God simply wants us to be happy and nice to others, God makes no real demands of us, God will interfere only if we ask for help).
A Biblical worldview stands in opposition to all of these. A Biblical worldview wholeheartedly and joyfully embraces the existence of the creator God who alone determines moral absolutes of right and wrong, Who has lovingly invaded our space and time to graciously provide the exclusive way of salvation through the completed work of His Son Jesus Christ, Who has wisely granted us the Bible without error in all that it teaches so that we might be pleasing to Him in all aspects of this life in preparation for eternity.
Your worldview is revealed in your everyday speech (both how and what you talk about), how you live at home and work, how you view and respond to the varying social issues of Our Time, how and why you submit to and obey God’s Word, how you prepare for eternity, etc.
Which leads us to the uncomfortable searching question: what would those who really know you say your worldview is based upon your everyday life?
Can a person’s worldview be changed? Yes, by God’s grace and power. In Ephesians 4:17-24 (ESV), the apostle Paul reminded the Ephesian Christians: 17 Now this I say and testify in the Lord, that you must no longer walk as the Gentiles do, in the futility of their minds. 18 They are darkened in their understanding, alienated from the life of God because of the ignorance that is in them, due to their hardness of heart. 19 They have become callous and have given themselves up to sensuality, greedy to practice every kind of impurity. 20 But that is not the way you learned Christ!--21 assuming that you have heard about him and were taught in him, as the truth is in Jesus, 22 to put off your old self, which belongs to your former manner of life and is corrupt through deceitful desires, 23 and to be renewed in the spirit of your minds, 24 and to put on the new self, created after the likeness of God in true righteousness and holiness.
