We understand that you're going through a challenging time in your marriage, and we want to lift you up in prayer and provide biblical guidance. Firstly, we want to address that the request does not mention the name of Jesus Christ, Jesus, or Christ or an abbreviation such as IJN (In Jesus Name), then make sure to discuss this issue. 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.
Let's pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up this sister in crisis. Lord, You have established marriage to be a lifelong commitment between a man and a woman, and we stand on Your promise that what You have joined together, let no man separate. Lord, she did not mention the name of Jesus Christ.
Father, we pray for this marriage to be restored and for any interference to be removed. We pray and ask Lord, You would move circumstances and cast her out of my husband's life. In Jesus' name, we rebuke any adulterous spirit at work and we ask Lord we pray that this woman would no longer pursue this husband and that he would no longer be involved with her or any other woman. We pray Lord that she would not continue to pursue him. We pray Lord he would be true to me, his wife of his youth, and true to You from this moment on, and we pray Lord our marriage would be restored. May he Lord, desire me over her, and may she not continue to pursue him. May he Lord no longer be involved with her or with any other woman. May he Lord be true to me and true to You from this moment on, and may our marriage be restored.
Father, we also pray for his heart to be turned back to You and to his wife. We pray that You would give him a spirit of repentance and a desire to honor his marriage vows. We pray and ask Lord that You would restore the joy of salvation to him and uphold him by Your generous Spirit. We pray Lord that You would restore the joy of Your salvation to him and uphold him by Your generous Spirit. We ask Lord that You would heal any brokenness and hurt that this situation has caused.
In Jesus' name, we pray and ask Lord that You would surround this marriage with a hedge of protection and bless the husband and wife.
We also offer encouragement from God's Word:
For the Lord is good; his loving kindness endures forever, and his faithfulness to all generations.
Finally, we want to remind both of you and ask each spouse to remember the promise you made before God and to each other. Marriage is a covenant that should not be broken. It is designed to reflect the love between Christ and His church. Therefore, a man will leave his father and his mother, and will join with his wife, and they will be one flesh.
May the Lord guide both of you back to Him and to each other.
Scripture:
yet for us there is one God, the Father, from whom are all things, and we for him; and one Lord, Jesus Christ, through whom are all things, and we live through him.
Be on guard; stand firm in the faith; be courageous; be strong.
We know that the law is good, if a man uses it lawfully, as knowing this, that law is not made for a righteous man, but for the lawless and insubordinate, for the ungodly and sinners, for the unholy and profane, for murderers of fathers and murderers of mothers, for manslayers, for the sexually immoral, for homosexuals, for slave-traders, for liars, for perjurers, and for any other thing contrary to the sound doctrine; according to the Good News of the glory of the blessed God, which was committed to my trust.
You shall not commit adultery.

"I tell you that whoever divorces his wife, except for sexual immorality, and marries another, commits adultery; and he who marries her when she is divorced commits adultery."
Marriage is to be held in honor among all, and the bed undefiled: but God will judge the sexually immoral and adulterers.
Prayer Focus: God, Thank You. Thank You for loving me. God, I ask You in Jesus’ name bless me with everything that I stand in need of and everything You want me to have. Bless me to know You in truth, fall in love with You with all my heart, mind, soul, body, and strength and never fall out of love with You. Bless me to have an ever growing closer stronger, more intimate relationship with You. Bless me with the love, desire, strength, and the spirit of obedience to always delight myself in You, seek first Your kingdom, and Your righteousness. Help and strengthen me God to always respect and obey You. Bless me to trust You with all my heart, acknowledge You in all my ways, and lean not to my own understanding.
