There are two types of purity everyone must focus on. The first is outward purity, which is the way in which you behave. Think about this: if your spouse were to watch a video of the way you behaved for an entire day, would they be proud or disappointed? Does the way you dress reflect purity? Does the way you talk reflect purity? Does what you look at or watch reflect purity?
Talk: Ask each other this question: What outward changes do you need to make to reflect a life of purity?
Pray: Ask God to convict you of any outward changes you need to make and to help you make those changes as you both strive for purity.
Do: Find a new or fun recipe and cook something together. While you cook, enjoy some great conversation.
