His text this morning was Mk 2.13-17 about Jesus eating and drinking with tax collectors and sinners. It is here where Jesus says that people who are well don't need doctors. People who are sick need doctors. He also says, "I did not come to call the righteous, but sinners" [2.17].
The way this should hit us is huge.
Give it a listen here ["You're in Good Company" on 11/02/08]. Trust me, ye shall be blessed [two syllables on "bless-ed"].
