If we’re honest with ourselves, we know there are libraries full of books that are full of information that we have no knowledge of. This realization, however, does not stop us from acting like know-it-alls when it comes to living our lives. But thanks be to God, there are those times when he has us fail miserably at something so that the blinders of our false self-perception are removed and we see how ignorant we really are. In those times it can be easy to fall into despair or hopelessness in regard to our lack of knowledge, which is why the doctrine of God’s omniscience should be the strong arm we grasp to lift us out of that pit.
The Apostle John gives us a profoundly simple definition of God’s omniscience when he writes, “[God] knows everything” (1 John 3:20). Not one of us on this earth operates on full knowledge, but God, the one who is in control of everything, also knows everything and works out his plan based on that knowledge. Wayne Grudem unpacks what it means that God knows everything when he writes, “Since [God] fully knows himself (1 Cor. 2:10-11), he fully knows all things that he could have done but did not do and all things that he might have created but did not create. He also knows all possible events that will not actually happen, and events that would have resulted if some other events had turned out differently in history” (Christian Beliefs, p. 27).
Essentially, what Grudem is saying is that we can rest assured that what actually happens in every second comes from the mind of our God who has weighed out every single possible option of how each moment could go and has determined, in his perfection, that what he planned is the best choice for that moment. So, whether you’ve failed miserably at something or you are suffering in some other real way, you can know that God has determined what takes place in that moment to be what is absolutely best for you. The doctrine of God’s omniscience is the reason why God can work all things together for the good of those who love him (Romans 8:28). We can’t have the promise of Romans 8:28 without the doctrine of God’s omniscience! Whatever you’re going through right now, you are not getting God’s plan B, C, or D. Because of God’s omniscience, it is his plan A for you every moment of every day!
