A couple of weeks after hearing a sermon on Psalms 51:2-4 (knowing my own hidden secrets) and Psalms 52:3-4 (lies and deceit), a man wrote the following letter to the IRS:

I have been unable to sleep, knowing that I have cheated on my income tax.  I understated my taxable income, and have enclosed a check for $150.00.

Sincerely, Taxpayer

P.  S.  If I still can't sleep, I will send the rest.
