John Newton on how to be humble when handling the treasures of Scripture:
To be enabled to form a clear, consistent, and comprehensive judgment of the truths revealed in the Scripture, is a great privilege; but they who possess it are exposed to the temptation of thinking too highly of themselves, and too meanly of others, especially of those who not only refuse to adopt their sentiments, but venture to oppose them. We see few controversial writings, however excellent in other respects, but are tinctured with this spirit of self-superiority . . .
I know nothing, as a means, more likely to correct this evil, than a serious consideration of the amazing difference between our acquired judgment, and our actual experience; or, in other words, how little influence our knowledge and judgment have upon our own conduct. . . .
[I]f we estimate our knowledge by its effects, and value it no farther than it is experimental and operative (which is the proper standard whereby to try it), we shall find it so faint and feeble as hardly to deserve the name.
