How to Use These Verses
Write two or three of these verses on an index card and place it where you will see it during your routine, such as the bathroom mirror, the dashboard, or inside your Bible. Choose the verse that matches your current season rather than reading the whole list at once, so each passage has room to work in your heart.

Bless my spouse today with your presence and peace. Make our marriage a place where your steadfast love is seen and felt. Help us keep our promises to each other and to you, for your glory and our good. Amen.
