As intimidating as it might sound, an experience of the wide expanse of the world and human nature is precisely what is needed to bring us to fully use and appreciate our own gift of being human. If the world is, in fact, a gift of God lovingly granted that we might know Him better, coming to know and appreciate it in fullness will be a sincere endeavor in Christian education.
The human experience itself is the greatest education we can find and a well-rounded education pushes us towards loving it fully.
How can education keep focused on being a well-rounded introduction to the wonderful life-long hobby of being human? A student who loves math should be stretched to learn to love a good story full of the observations about human character that come with good writing. When a student would love to spend his days tearing through novel after novel, he also needs to work through the world of mathematics and the careful world of analytic thought. The rhetorical puppy dog who only loves to debate politics or other easily controversial topics needs to learn to sing in harmony and experience the joy of dance with pleasant female companionship.
As we seek to live well and gain wisdom, the whole counsel of life is often a wonderful guide and friend. Living life is an education itself, so a good teacher pushes the student to use the freedom of his youth to take the time to learn from a wide scope of experience and take advantage of the learning that can be found scattered about the playground of life.
