We understand your urgency and desperation, but let's focus on aligning your requests with biblical principles. Firstly, it's important to note that comparisons with other women are not beneficial. The focus and only comparison should be of your self to Jesus Christ. The only perfect relationship and bond should be of you and Jesus Christ. Your prayer should be for your husband to be the Godly man he is called to be. Your prayer should be for your marriage to be God-centered. Your prayer and focus should be for you and your husband to have God's grace, forgiveness, wisdom, and the love that flows from relationship with Jesus Christ.
It is encouraging that you mentioned the name of Jesus Christ, as it is only through Him that we have access to God. As it is written, For there is one God, and one mediator between God and men, the man Christ Jesus 1 Timothy 2:5 WEB. And again, In whom we have boldness and access with confidence by the faith of him Ephesians 3:12 WEB.
Let's pray for your husband's salvation and the sanctification of your marriage. Let's pray for God to fill both of you with His Holy Spirit, that you both may be united in Christ and live according to His will.
Let's pray:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up this dear sister and her husband. We pray that You would have mercy on them and save them both, filling them with Your Holy Spirit. We pray for their marriage to be a testament to Your glory, that it would be strong, loving, and filled with passion according to Your will. We pray for their eyes to be fixed on You and that they may have their relationship and love, be a reflection of your love and relationship with your children. Help them to love each other as You have loved us first. Help them to love one another as they love themselves.
We rebuke any spirit of comparison, jealousy, or selfish ambition, and we ask that You would help them to focus on You and Your will for their lives and marriage. We pray that they would be one, even as You and Jesus are one, that their marriage may bring glory to Your name.
We ask this in the name of Jesus Christ, our Lord and Savior. Amen.
We encourage you to trust in God's will for your life and marriage. Remember that God's ways are not our ways, and His thoughts are not our thoughts. His ways and thoughts are higher than ours. Trust in Him, and He will direct your paths.
Also, consider the words of Paul in Ephesians 5:22-33 WEB: Wives, be subject to your own husbands, as to the Lord. 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. But as the assembly is subject to Christ, so let the wives also be to their own husbands in everything. Husbands, love your wives, even as Christ also loved the assembly, and gave himself up for it; that he might sanctify it, having cleansed it by the washing of water with the word, that he might present the assembly to himself gloriously, not having spot or wrinkle or any such thing; but that it should be holy and without blemish. Even so ought husbands to love their own wives as their own bodies. He who loves his own wife loves himself. For no man ever hated his own flesh; but nourishes and cherishes it, even as the Lord does the assembly; because we are members of his body, of his flesh and bones. For this cause a man will leave his father and mother, and will be joined to his wife. The two will become one flesh. This mystery is great, but I speak concerning Christ and of the assembly. Nevertheless each of you must also love his own wife even as himself; and let the wife see that she respects her husband.
Finally, we want to explicitly remind you that any thoughts, words, or actions that do not align with God's will as described in the Bible are sinful. They should be repented of and you should strive to change your heart and mind to better reflect God's will. If you are focusing on yourself, your husband, or even your marriage more than Jesus Christ, it is sin. If you are comparing yourself or husband to others or any thing other than what the Bible says a Godly husband or wife should be, it is sin.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
