Summary: A true worldview must make sense. If Christianity is actually the truth about everything, then we can and should be able to understand it in an intellectually coherent manner.
Let's look at a progression from worldview to practice, quickly running through seven areas of growth in understanding and faith practice.
1. Intellectual Coherence - A true worldview must make sense. If Christianity is actually the truth about everything, then we can and should be able to understand it in an intellectually coherent manner. Now, there will and in fact should be certain aspects of Christianity that are mysterious. If we are in fact created beings created by an infinite God, then logically a system created by a God infinitely more knowledgeable and powerful than us will have aspects beyond our comprehension.
We will also have to assume that God's moral viewpoint is higher than ours. That is the hard part. Because often we can become quite indignant about our own moral viewpoints. But God's view must be higher and more clear, if He is in fact God of the universe and the creator of all ethics.
Intellectual coherence means that God's existence is reasonable. I've found that to be the case. Whether from science, history, manuscript authenticity, and real world experiences, there is a great amount of evidence that God exists.
2. Experiential Relevance / Experiential Integration - As we recognize the reality of the Christian worldview, it becomes integrative, it changes how we see reality. The word of God is the codex to deciphering the perceivable universe. We can decrypt reality with the Biblical documents.
This is difficult because a lot of us have opinions and viewpoints on things in the world that may have to change as Jesus transforms our worldview. But the goal is to see ultimate truth, and to see perceivable reality as it truly is, not as we would want it. That is difficult. It is very difficult. Because we have strong viewpoints and opinions on many things. But if we allow the biblical documents to begin to transform our worldview, we'll begin to see the whole world with a new clarity that amazes us.
3. Biblical Grounding - Our tendency as humans is toward drifting. If we're not moving toward something, we're actually being moved away from it. That's what it's like to swim in the current of this life. Standing firmly on the scriptures is a dedicated approach to life, a dedicated total trust in the words of the scriptures to accurately depict reality and define ourselves, the past, the future, what it means to live ethically, and our future destiny. There are four key tests of a worldview: Origin, meaning, morality, and destiny. And the Bible brings answers clearly to all four of those areas of philosophical concern.
But the point here is, that our tendency is toward drifting. If we don't intentionally move toward a biblical worldview, we will drift away from one over time. The world is communicating a worldview that is systemically contrary to biblical Christianity. If we aren't intentionally absorbing a biblical worldview, then we'll be unconsciously adopting a humanist/naturalistic worldview, or something even more spooky, like a cult, or extreme political ideology.
4. Sustaining Dependence - Recognizing our infinite need for God, a sustaining relationship makes it possible for us to victoriously live out the Christian life. This sustaining relationship heals us, delivers us, guides us through difficulty, overcomes evil within us, and without us, and guides us toward our ultimate end destination.
The will of God is constantly at work. Once again, without intentional focus on this connection, we drift. There is no standing still, we're either pressing forward or drifting away.
Our relationship with God must be constantly developed. And we look to strive deeper and deeper with God, expanding the connection continuously, as God transforms us into the likeness of Christ.
Take this relationship to a new level. Dedicate real time each day to this relationship. We can talk all we want about how "it's a relationship" but that doesn't mean anything if we aren't dedicating any time to it. The fact on the ground is, either we are really living in relationship with God, or we're really not. And our life and fruit (results of our actions practically) will show which is true, for all to see.
5. Lifestyle Method - Ordering your life means living out the convictions of the truth on a daily basis. Week in and week out. A lifestyle method is the practice of our relationships with God first, with our marriage wife or husband, and our friendships, and relationships with people and the church.
We need a weekly lifestyle method that we dedicate ourselves to. I mean a weekly pattern of life, a methodism of life. I'll tell you about my method: Monday, morning prayer, work/school, 7pm basketball, 9pm-10:30pm bible study/ prayer time. Tuesday, morning prayer, work/school, homework time/relaxation, then bible study/prayer time 9pm-10:30pm. That goes on day by day, week by week, and so on. I try to carefully order my life, Bible studies, small groups, church services on Sunday, evangelism, and service work. If we're followers of Jesus, we should order our lives carefully around Christian practices.
