Leviticus 2 

"All mankind today is a little 'off.' We're all just a little off-center."
   –Attributed to Dr. Karl Menninger 

Leviticus 4:1-12 and Leviticus 5 

"Mel Trotter told about the time he had a doctor on his missions board back in Grand Rapids, Michigan, and they got down on their knees every Saturday morning. Each board member would pray, and this man would pray, 'Lord, if we committed any sin, forgive us.' Mel got tired of him saying that little formula, that little Christian cliché you hear today, and he tried to say to him, 'Why don't you tell Him what the sin is?' And this doctor said, 'I don't know what it is.' And Mel said, "Well, why don't you guess at it?' And then the fellow made the statement. He said, 'You know, he hit it the very first thing!' "
   –Dr. J. Vernon McGee

You're Writing a Gospel, Someone Has Said...
You’re writing a gospel, a chapter a day
By deeds that you do and words that you say.
Men read what you write, whether false or true.
What is the gospel according to you?
