Prayer to Lord to Convince My Partner’s Parents to Our Marriage and Accept me Happily as their Daughter in Law

Dear Lord

Please convince my partner’s Mother and Father to our marriage and make them accept me happily as their daughter in law.

I promise to love and cherish them like my own parents. Lord please give some clarity to his mother who refuses to get us married because of different caste. Please clear and remove any and all doubts she has and fears she has due to caste.
