Worldview is really about the glasses one looks at life through. Glasses, because we are not speaking about seeing objectively through the native or natural lens that's part of the eye, but of something that is adopted by the seer or instilled by the environment, and through which one sees their all-compassing perspective of life. Belief in Christ is one such viewpoint, which when adopted is meant to impact the believer sufficiently to change, develop and instill an all-encompassing way of looking at life and living. The gospel is meant to cause us to see life, not through blue eyes or brown eyes, but through Jesus eyes.
So, it’s important to understand the means by which one adopts such a Christian worldview. Using a phrase like this may lead one to think that a believer merely accepts a series of propositions and endeavors, as best he or she can, to apply those precepts to their living. That is not at all the case, though I think sometimes Christians think that way and that teachers of the faith sometimes teach like that is the case. Whereas that certainly is the case in other ideologies, it is not at all the case in true faith in Christ.
Belief in Christ is about a quantum change in our nature. A metamorphosis so fundamental that the Christian, upon coming to sincere trust in Christ, becomes a new being--a creature different in its nature than it was before. That is not to say that the Christian decides this, or adopts this by choice and thereby makes it so, even if by remarkable effort. This change is the result of the introduction and infusion of a catalyst, a change agent, in this case a change person, namely, the Holy Spirit.
The simple truth is that no one can even come to Christ and believe in him unless that one is drawn by the Father (through auspices of the Holy Spirit, it seems to me). The conviction of heart and mind in regard to Christ which undergirds repentance, in my mind, comes through the Holy Spirit as well. It is the Holy Spirit interacting with humans that empowers them to have a faith which allows Christ to dwell in their hearts at all. It is that presence, power and action of the Holy Spirit which is the foundation of a Christian worldview.
The Holy Spirit is our lens.
Christians do not see life in a Christian manner by mere choice, but through a lens actualized and activated by the Holy Spirit. The faith that responds to and partners with the Holy Spirit becomes an all-encompassing perspective on life for the one born again. If that is not present in one claiming the faith, there is no way that one can truly be in the faith. Actually being born again matters.
Are you born again? Do you have a Christian worldview?
