A shelf in my head?

Spurgeon, "Christ- The Power and Wisdom of God" Before I knew the gospel I gathered up a heterogeneous mass of all kinds of knowledge from here, there, and everywhere-- a bit of chemistry, a bit of botany, a bit of astronomy, and a bit of this, that, and the other. I put them altogether, in one great confused chaos. When I learned the gospel, I got a shelf in my head to put every thing away upon just where it should be. It seemed to me as if, when I had discovered Christ and him crucified, I had got the center of the system, so that I could see every other science revolving around in order. From the earth, you know, the planets appear to move in a very irregular manner- some are progressive, retrograde, stationary, etc. But if you could get upon the sun, you would see them marching round in their constant, uniform, circular motion. Likewise with human knowledge. Begin with any other science you like, and truth will seem to be amiss. But if you begin with the science of Christ crucified, you will begin with the sun- you will see every other science moving around it in complete harmony. The greatest mind in the world will be evolved by beginning at the right end. The old saying is, "Go from nature up to nature's God." But it is hard work going up hill.
