You can learn more about human nature by reading the Bible than by living in New York. (William Lyon Phelps, 19th-20th century scholar, author, critic)
With its broad spectrum of ethnic origins, levels of education, and social differences, you might think that a study of the people of New York City would render a pretty accurate description of human nature. Phelps is suggesting, however, that a better and unbiased viewpoint on the full and accurate picture of humanity is to be found in God’s own perspective, the Bible.
The sinful nature wants to do evil, which is just the opposite of what the Spirit wants… These two forces are constantly fighting each other, so you are not free to carry out your good intentions. (Galatians 5:17)
