If knowing more about people and the world around us helps us better understand God and his creation (see Psalm 19 for encouragement here), how does that change my day-to-day life? For starters, we should not take education lightly. As we just saw, it is a deep and weighty thing that we have the privilege to engage in.
More practically, we should see a call to be faithful and diligent in our studies. It can be easy to lose sight of that in the midst of a busy life. When you have bills to pay, a job to work, family and relationships to manage, one paper for one class might seem inconsequential. Perhaps it is something we can skip, just this once. While the paper itself may be inconsequential, the study and care behind it are not. If God is with us, and we can be more aware of his presence when we devote ourselves to learning about him, then that is an obligation you and I must take seriously.
Follow my thinking here. The greatest commandment is to love God and love your neighbor as yourself (Mark 12:30-31). Jesus equates loving God with obeying the commandments he has given (John 14:15), but this also assumes we know what those are. And how can we know who God is and what he wants if we have not studied: studied the Bible, studied the world and studied ourselves? Applying ourselves to our education is vital, then, to following God.
Now this does not mean that getting a C or, heaven forbid an F, on a test means you have somehow failed in your Christian walk. God wants you to apply yourself with the gifts he has given you, but he is not judging you based on the eventual outcome, only the faithfulness of your effort. It is so important to remember that two servants were called good and faithful in the parable of the talents (Matt. 25:14-30). They did not start at the same place, or achieve the same results, but both simply applied what they had; that is all God asks of us here as well.
