We understand your urgent desire for your husband's salvation and the unity in your marriage. It is commendable that you are seeking God's intervention in your husband's life and your marriage. We will pray with you and offer biblical guidance.
Firstly, it is essential to remember that we cannot force someone to become a born-again Christian; it is a personal decision that each individual must make. However, our prayers and testimony can have a powerful influence. As Peter said, "Wives, in the same way, be submissive to your husbands so that, if any of them do not believe the word, they may be won over without words by the behavior of their wives when they see the purity and reverence of your lives." (1 Peter 3:1-2 WEB)
Regarding the unity in your marriage, it is wonderful that you are seeking to be in total agreement. The Bible tells us, "I appeal to you, brothers and sisters, in the name of our Lord Jesus Christ, that all of you agree with one another in what you say and that there be no divisions among you, but that you be perfectly united in mind and thought." (1 Corinthians 1:10 WEB)
However, we must address that the desire for your husband to have eyes only for you and for your love to grow more passionate each day should be approached with biblical understanding. The Song of Solomon teaches us that intimacy and desire are God's design for marriage, but we should also be aware of God's will for our lives as a whole.
Let us pray together:
"Father, we come before you in the name of Jesus Christ, lifting up our sister and her husband. Lord, we pray that you would soften his heart and draw him to you, that he may become a born-again Christian. We pray for unity in their marriage, that they would be of one mind and heart, aligned with your will. We ask that you bless their relationship, strengthening their bond and deepening their love for each other, but above all, their love for you. Help them to be a testimony of a godly marriage and guide them in your paths. We pray that you will help them to be an example of a Christian marriage, with love and devotion that aligns with your will for them. In Jesus' name, we pray. Amen."
We encourage you to continue praying fervently for your husband's salvation and your marriage. Remember that God's will is paramount, and His ways are higher than ours. Trust in Him and His timing. Be a testimony of God's love and grace, and let your light shine before your husband that he may see your good deeds and glorify your Father in heaven (Matthew 5:16 WEB).
We are reminded that the husband is to be the spiritual leader of the home, and the wife is to be his helpmate. A relationship in courtship is always looking for a marriage with a Christian Believer. Continue to study the scriptures together when appropriate to become equal yolks. When marrying a Christian man and woman together, they should be a set of oxen together pulling the load under the guidance of the Holy Spirit. God intends for the best marriage to be a man and woman united to Him first and then to each other.
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.
