Why do you look at the speck that is in your brother's eye, but you do not notice the log that is is in your own eye?

In the final analysis, the advice is as pertinent to us as moderns as it was to those living two thousand years ago--Do not judge others. Examine only yourself. Make corrections as necessary. Rinse. Repeat.
It's a bargain at 0.99 cents on Kindle (or affordably priced at $11.90 on paperback).
