Acts 23:1
"And Paul, earnestly beholding the council, said, Men and brethren, I have lived in all good conscience before God until this day."
Paul said, "I have lived in all good conscience..." That statement is a mouth full. To be able to say that you have a good conscience is to say that you have no skeletons in the closet that you are trying to hide. A good conscience is not what you portray to others, but knowing you've done right in private at all times.
