The true method of knowledge is experiment.
There are some Christian people who taste and see and enjoy religion in their own souls, and who get at a deeper knowledge of it than books can ever give them, though they should search all their days.
Wisdom is the right use of knowledge. To know is not to be wise. Many men know a great deal, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom. – Charles Spurgeon
