We understand your concern for your elder daughter, and we want to assure you that we are here to pray and seek God's will together with you. Let us remember the words of Proverbs 22:6 (WEB), "Train up a child in the way he should go, and when he is old he will not depart from it." Though she may be straying now, we trust that the seeds of wisdom and faith you've planted in her will bear fruit.
Firstly, we want to encourage you to continue praying in the name of Jesus, as it is the only name by which we can be saved and have access to God. As it is written in Acts 4:12 (WEB), "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
Now, let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus, lifting up our sister's elder daughter to You. Lord, we ask that You grant her wisdom and a willing heart to understand and obey her parents. Help her to see the value of hard work and responsible stewardship of her resources. Turn her heart away from any bad habits and the distractions of the world, and draw her closer to You.
We also pray for our sister and her husband, that You would grant them patience, wisdom, and grace as they guide their daughter. Help them to set a godly example, and to love and discipline her as You do for us, Your children.
Lord, we trust in Your promise in Philippians 1:6 (WEB), "Being confident of this very thing, that he who began a good work in you will complete it until the day of Jesus Christ." We know that You are faithful to complete the good work You've started in our sister's daughter.
In Jesus' mighty name, we pray. Amen.
Lastly, we want to encourage both you and your husband to be steadfast in your love and discipline. Continue to demonstrate a godly marriage and family life, and trust that God is working in your daughter's heart. Be vigilant in your guidance, but also be patient, remembering that God's timing is perfect.
