We are truly sorry to hear about the struggles you are facing in your marriage. Let us first assure you that you are not alone in this battle, and we are here to intercede for you and offer biblical guidance.
Let's pray together:
Dear Heavenly Father,
We come before you today, lifting up this sister in Christ and her marriage. Lord, you know the struggles she is facing, the pain she is feeling, and the fear that is gripping her heart. We ask, Father, that you would intervene in this situation and bring healing and restoration to this marriage.
Lord, we pray for her husband, that you would deliver him from the stronghold of alcoholism. We know that this is a battle that can only be won through your power and strength. Please help him to see the light of Christ and turn away from this destructive path. We ask that you would give him a heart that desires to spend time with his family and to be the spiritual leader in their home.
Father, we also pray for this sister, that you would strengthen her faith and give her the courage to trust in you completely. Help her to cast all her anxieties on you, because you care for her. We ask that you would fill her with your peace, which surpasses all understanding, and that you would guide her steps as she navigates this difficult time.
We pray all of this in the mighty name of Jesus Christ, our Lord and Savior. Amen.
Now, let us address some biblical principles and encouragement for you, sister.
Firstly, it is important to remember that God hates divorce. In Malachi 2:16, God says, I hate divorce, says Yahweh, the God of Israel. Therefore keep watch over your spirit, that you don't deal treacherously. So, we encourage you to keep fighting for your marriage and to not give up hope.
Regarding your husband's alcoholism, we must remember that drunkenness is a sin. In Ephesians 5:18, Paul tells believers in Christ, Don't be drunken with wine, in which is dissipation, but be filled with the Spirit. We encourage you to speak the truth in love to your husband about his drinking, and to set boundaries to protect yourself and your child.
It is also important to remember that God calls husbands to be the spiritual leaders in their homes. In Ephesians 5:23, Paul says, For the husband is the head of the wife, as Christ also is the head of the assembly, being himself the savior of the body. We encourage you to pray for your husband, that God would give him a desire to lead his family spiritually and to be the man of God that he is called to be.
Lastly, we want to encourage you to cast all your anxieties on God, because he cares for you. In 1 Peter 5:7, Peter says, casting all your worries on him, because he cares for you. We know that this is a difficult time, but we encourage you to trust in God and to rest in his promise to never leave you nor forsake you.
Remember, sister, that it is only by the name of Jesus that we have access to God. It is by Jesus’ stripes that we are healed. We pray that you both come to know Jesus more intimately and that it would be reflected in your marriage.
Stand strong in faith and continue to bring your requests before God. He is faithful to hear and answer our prayers.
