If you’re having a religious wedding, it’s appropriate to have religious sand ceremony vows. Your officiant can add in scripture or prayers, and might already have a standard wording to use. Here is a basic format:
“Therefore a man leaves his father and his mother and clings to his wife, and they become one flesh” (Genesis 2:24). God created you as an individual, perfect by His glory and love. But God also said that it was not good for man to be alone, and so he created woman to be his partner and helper. Today as you make a covenant before God to join in marriage, you become one flesh. You have chosen to symbolize that union with a sand ceremony.
First, I will pour in white sand, representing your faith in God as the foundation of who you are as individuals. Now _____, pour some of your sand, representing yourself as an individual before you came to this union. Now _____, also pour some of your sand, representing yourself as an individual before you came to this union. I will then pour some more white sand, representing your faith in God as the foundation of your marriage.
Then, _____ and _____ pour your remaining sand together to represent your joining as one in marriage completely and eternally. Lastly, another layer of white sand represents God watching over you and protecting you with his everlasting love.
May God bless this marriage so that you are as inseparable as these grains of sand. Amen.
