How can we store up such a great accumulation of wisdom as we find in this book? Not all at once, but by constant reflecting on what God says to us. Memorization of course but the constant bringing of what we have already learned to each new issue we face in life. The gaining of knowledge is a gradual process involving spiritual growth. We have to be constantly giving attention to it. Like all growth, it happens by the accumulation of small increments. Yes, there are certain key experiences which seem to advance us in a significant way which we look back on as deeply formative, but mostly it is something we have to be doing constantly. Knowledge is not something which we take and store somewhere within us in a separate room. It must become part of us. It is more like material which we use to build new rooms in the house. As food is broken down into its elemental parts by the digestion process, and then reassembled into specific molecules which repair and form new tissue in our bodies, so it is with knowledge. Knowledge is digested by the mind as it reflects on all its implications and weighs its reliability and accuracy. Once trusted as truth, it is accepted into the inner sanctuary of the soul and adds to it, becoming part of our thoughts. We think using that knowledge and our thoughts take new paths that they would not have taken without it. Knowledge is like strong muscles that are able to walk up steep hills; it is like a solid frame that is able to bear considerable weight; it is like skilled movement that is able to accurately perform a complex task.
