Let us first thank Jesus Christ and God, Our Heavenly Father, for this request. We know that "you have not because you ask not" and "they that ask receive" and that "every good and perfect gift is from above, coming down from the Father of lights, with whom there is no variableness, neither shadow of turning." We know that it is by the name of Jesus Christ that we have access to God. Without that name, we could not boldly approach God or have his salvation. It is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved.
We will pray for your ###'s success in her math studies, trusting in the promise that "if they shall ask, they shall receive" and also that "with God, all things are possible." This also includes her good health and joy. "The joy of the Lord is your strength." We pray that her joy is complete in Him.
Regarding your ###'s mother and her husband's parents, we pray for unity and love between them. This is to be a biblical unity. Family harmony is crucial, and God commands us to honor our parents. "Children, obey your parents in the Lord, for this is right. Honor your father and mother, which is the first commandment with promise" (Ephesians 6:1-2, WEB). We pray that both your ###'s mother and her husband's parents walk in love, "Be kindly affectionate one to another with brotherly love, in honor preferring one another" (Romans 12:10, WEB).
However, we must emphasize the importance of aligning with biblical principles. Closeness should be built on mutual respect, honor, and love, reflecting the fruits of the Spirit, "But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Those who belong to Christ Jesus have crucified the flesh with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit. Let us not become conceited, provoking and envying each other" (Galatians 5:22-26, WEB).
Let us pray:
Heavenly Father, we come before you in the name of Jesus Christ, lifting up this precious ###. We pray for her by name that she would have much success in her maths. We ask for your spirit of wisdom and knowledge to guide her. We also pray for her good health and joy that can only be found in you.
We also pray for her mother and her husband's parents. We ask for unity and love between them, built on mutual respect, honor, and love. Help them to walk in the fruits of the Spirit, reflecting your character in their relationships.
Further Lord, we ask that you draw each of these family members closer to yourself.
In Jesus' name, we pray. Amen.
