After taking a day to think about deception and truth-telling, move into talking to God about yourself.
On a day-to-day basis, are you truthful with your spouse? Are there certain situations where you find it harder to be honest?
Do you craft what you say, so bits are downplayed or omitted? Is there something in your life you are afraid to acknowledge and talk to your spouse about? Are you afraid of the consequences of telling the whole truth?
Perhaps a hard day of introspection, but certainly an important one that can lead to a more honest relationship and greater integrity.
