As we gear up for the new school year, it is important to remember how a biblical worldview affects the correct instruction of our children:
"Now the fact that two times two are four does not mean the same thing to you as a believer and to someone else as an unbeliever. When you think of two times two as four, you connect this fact with numerical law. And when you connect this fact with numerical law, you must connect numerical law with all law. The question you face, then, is whether law exists in its own right or is an expression of the will and nature of God. Thus the fact that two times two are four enables you to implicate yourself more deeply into the nature and will of God. On the other hand, when an unbeliever says that two times two are four, he will also be led to connect this fact with the whole idea of law; but he will regard this law as independent of God. Thus the fact that two times two are four enables him, so he thinks, to get farther away from God. That fact will place the unbeliever before a whole sea of open possibilities in which he may seek to realize his life away from God. And it is this basic difference between what "two times two are four" means to the believer and what it means to the unbeliever that the doctrine of common grace has helped us to see."
