Here is a sample prayer for a good marriage that you can use as a guide:
Dear God,
I pray for my marriage today. Please bless our union and help us to grow in love and respect for one another.
I pray for your guidance and wisdom as we navigate the ups and downs of life together. Please give us patience and understanding as we work through challenges and conflicts.
Help us to always put each other first and to seek your will in all that we do. May our love for each other be a reflection of your love for us.
Please bless our marriage and keep us united in your love.
In your holy name I pray, Amen.
