"Be completely humble and gentle; be patient, bearing with one another in love." (Ephesians 4:2)
For the next day, demonstrate patience and say nothing negative to your spouse. If you are tempted choose not to say anything. It is better to hold your tongue than to say something you'll regret.
"Everyone must be quick to hear, slow to speak and slow to anger."(James 1:19)
Feel free to share a moment that happened today that you were able to demonstrate patience.
Were you able to go an entire day with this dare? If not keep practicing today and then try again for tomorrow to be an entire day. Let us know how you did. And not speaking to your spouse at all doesn't count :).
