The ones I overlook are the small ones. Sins of the heart and tongue. Grumbling about my circumstances, judging a stranger in the checkout line, stretching a story, ignoring a need I could easily meet.
Ingratitude too. I rarely think to confess the hours I spend fretting over what I lack while saying nothing to God about what I have.
A few minutes at the end of the day asking where I was impatient or self-centered has turned up more than I expected.
