Sin.
We think of the loud thunderous glaring gongs of sin—“big things” like sex, drugs, abuse, perversion, murder.
But Peter starts off chapter two with five subtly slimy subversions [1 Peter 2.1]:
So put away malice, and all deceit, and hypocrisy and envy and slander.
Five things that mostly want to harbor in my heart or spill out of my mouth.
Oh, Peter, why do you have to be so precise?
