We are truly saddened to hear about the struggles your daughter is facing, but we are encouraged by your faith and trust in the power of prayer. We stand with you in the name of Jesus Christ, as it is only through His name that we can approach God the Father and find salvation. Jesus is not a mere prophet or teacher, but the very Son of God.
Firstly, we acknowledge that God hates divorce. God has said, I hate divorce, says Yahweh, the God of Israel and the one who does violence to his own clothing, says Yahweh of Armies therefore pay attention to your spirit, that you do not deal treacherously Malachi 2:16 (WEB). We pray that your daughter's husband will truly repent and return to God and to his family. Pray with us, Father, in the name of Jesus Christ, we bring this marriage into your hands, if there is anything or anyone hindering this marriage from being restored, please remove it. Restore them God. We also pray for your daughter's husband, if he has not yet trusted in Jesus as his Savior. We pray that he will come to trust in Jesus and have his life transformed.
In regard to your daughter's anxiety and depression we are reminded of the following:
Do not be anxious about anything, but in every situation, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus. Philippians 4:6-7 (WEB)
Cast your burden on Yahweh, and he will sustain you. He will never allow the righteous to be moved. Psalm 55:22 (WEB)
Let us pray together:
Father, we come before You in the mighty name of Jesus Christ, lifting up our sister who is going through a difficult time. We pray for her deliverance from all anxiety and depression. We rebuke these spirits in the name of Jesus and command them to leave. Father, surround her with God-fearing people who will support, encourage, and help her draw closer to You and Your word. Guide her steps, heal her heart, and let her know Your unfailing love. Help her to fix her mind on Jesus and the truth of Your word. Please restore the marriage as only you can do. We also pray for the husband and father of these children, we pray that he will turn from his ways and return to God. We pray that he will turn from his sin and trust in Jesus if he has not. We pray that he will return to his family and be the husband and father that you have called him to be. Protect the children as well and give them the love for you needed at this age.
Sister, continue to trust in the Lord with all your heart and lean not on your own understanding and He will direct your paths. Remain steadfast in prayer and the study of God's word. Encourage your daughter to do the same.
In Jesus Christ's name, we pray. Amen.
