How does the Christian faith reconcile the apparent conflict between the randomness observed in nature and the providence of God?
In a series of blog posts over the next few weeks, we will discuss this question, which frames a key issue for how we integrate an understanding of natural processes, scientific analysis and the Christian faith.
It is argued that the existence of randomness in physical processes is fully compatible with a biblical understanding of the sovereignty of God.
The Merriam-Webster Dictionary provides two primary definitions for the adjective “random.”
- “lacking a definite plan, purpose, or pattern”
- “relating to, having, or being elements or events with definite probability of occurrence”
The second definition is that normally used by scientists and mathematicians when referring to the processes and samplings in nature found to be governed by statistical probabilities; hence, the ubiquitous use of the term “randomness” in the characterization of nature and our limitations in the prediction of natural occurrences. The Christian doctrine of divine providence teaches that God is actively involved with his creation – directing, guiding and giving it purpose. Nature’s randomness and God’s providence appear to be in conflict.
We are very familiar with random events in our daily lives. The flipping of a coin is considered a mathematically random process with equal probability of landing heads or tails. This randomness is built into the nature of the process and the symmetry of the coin that also limits us to only two possibilities. If we flip a coin 100 times and record our results, we can generate a sequence of heads (H) or tails (T) that would look something like this:
The sequence is random, and each particular ordering of heads and tails has a very low probability of occurring (one in 2100), with all sequences having an equal probability. The most probable number of flips that come up heads is 50 (we get heads 50 percent of the time), but it is physically possible that far fewer or far more flips turn up heads.
This process is characterized by statistical probabilities. If we should complete one million coin flips, we would find that the average number of flips that come up heads will come closer and closer (converge) to 50 percent. Scientists have consistently observed that natural processes can be characterized by such statistical probabilities and “randomness.”1
This has led many scientists to suggest that nature also adheres to the first definition of random in that it lacks a definite plan or purpose. Can we assume the second definition applies to nature without concluding the first definition must also? If statistical probabilities govern the processes of nature, how could this be consistent with the definite plan and purpose of God? How could God direct His creation to fulfill His purposes? Must a Christian conclude there is an incompatibility between natural randomness and the providence of God or can these be reconciled? Does the omnipotence of God guarantee that His sovereignty governs the randomness of nature?
If there are two distinct definitions for “randomness,” would one be compatible with God’s providence? If so, then clearly when we are engaging in scientific or philosophical discourse, we must be certain which definition we are using and in what context we are using it.
We can illustrate why this is important to the Christian. Grudem’s well-cited text on systematic theology summarizes the traditional objections to theistic evolution,2 “The clear teaching of Scripture that there is purposefulness in God’s work of creation seems incompatible with the randomness demanded by evolutionary theory. … The fundamental difference between a biblical view of creation and theistic evolution lies here: the driving force that brings about change and the development of new species in all evolutionary schemes is randomness. Without the random mutation of organisms you do not have evolution in the modern scientific sense at all. Random mutation is the underlying force that brings about eventual development from simplest to the most complex life forms. But the driving force in the development of new organisms according to Scripture is God’s intelligent design.”3
And later, “But once a Christian agrees to some active, purposeful design by God, then there is no longer any need for randomness or any development emerging from random mutation.”
If we assume in this quotation “randomness” means without purpose, plan or design, then such randomness associated with evolution or any scientific theory would be in conflict with the traditional Christian doctrine of divine providence. Then, the objection to theistic evolution articulated here would be totally accurate and well substantiated.
However, if “randomness” is restricted to mean that relevant processes are characterized by statistical probabilities, then such a view might not be incompatible with a purposeful, directing, sustaining and ”providential” God.
Similarly, the reformed theologian R.C. Sproul refutes the determinative power of chance, “The mere existence of chance is enough to rip God from his cosmic throne. … If chance exists in its frailest possible form, God is finished.”4
These assertions frame our question: Can nature operate by apparently random processes that conform to statistical probabilities and simultaneously be directed by God’s providential hand?

- 1 Scientists can point out that an unpredictable process such as coin flipping may be subject to statistical probabilities, but that underlying variables (e.g. the speed, angular momentum, trajectory of the coin and how it lands) will “determine” the outcome. Scientists disagree whether physical processes governed by quantum mechanics are “deterministic.” The Copenhagen interpretation championed by Bohr and Heisenberg argues that quantum uncertainty is inherent and not deterministic, whereas Einstein, de Broglie and, more recently, Bohm argue it is only statistical based upon the limitations to measurement capabilities.
