"Who can understand his own errors?" None can to the depth and bottom. In this question there are two considerables: 1. A concession; 2. A confession. He makes a grant that our life is full of errors; and the Scriptures say the same while they affirm that "All we like sheep have gone astray" (Isa. liii. 6); "I have gone astray like a lost sheep" (Psa. cxix. 176); that the "house of Israel" hath "lost sheep," Matt. x. 6. I need not reckon up the particulars, as the errors of our senses, understandings, consciences, judgments, wills, affections, desires, actions, and occurrences. The whole man in nature is like a tree nipped at the root, which brings forth worm-eaten fruits. The whole man in life is like an instrument out of tune, which jars at every stroke. If we cannot understand them, certainly they are very many."

Robert Abbot, 1646, was an English theologian who promoted puritan doctrines.
