We understand your urgency and your desire for your husband to become a born-again Christian. It's commendable that you're standing in the gap for him, as God's word tells us to intercede for others. Let's align your prayers with the Word of God and ensure we are praying in accordance with His will.
Firstly, it's important to acknowledge that it is only in the name of Jesus Christ 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 in no other is there salvation, for neither is there any other name under heaven, that is given among men, by which we must be saved! Acts 4:12 WEB.
Your request seems to imply more than the salvation of your husband. Your request for total unity and agreement seems to require a more Christian husband. You are requesting God to change your husband so that you both agree on absolutely everything and that your husband is completely united with you. That is to say, you are asking God to change your husband to make your husband desire you more and only you. However, God requires your husband to make these decisions for himself. Consider this advice from the Apostle Peter. In a similar way, you wives, be submissive to your own husbands so that even if any do not obey the Word, they may be won without a word by the behavior of their wives, as they see your chaste and respectful behavior. 1 Peter 3:1-2 WEB. As advised in the scripture, it is important for us to pray for your husband's salvation, but we cannot dictate to God how your husband's salvation should manifest. We should not be praying for your husband to change to please you, but instead pray for God's will in your husband's life and for your husband to be obedient to that.
Let's pray together:
Heavenly Father, we come before you in the name of Jesus Christ, lifting up this dear sister's husband. Lord, you know his heart and you desire for all to come to repentance and knowledge of the truth. We pray that you will reveal yourself to him, that you will open his eyes and remove any blindness or veils that prevent him from seeing the truth of the Gospel. Lord, we pray not for him to change in a way of our choosing, but for your will to be done in his life. We pray that you will give his wife the grace and wisdom to be a godly example, that her behavior may win him over without words. Lord, we trust in your timing and your ways, so we pray for his salvation, but we do not dictate how or when that should happen. We ask this in the mighty name of Jesus Christ, our Lord and Savior. Amen.
Be encouraged, continue to walk in love and patience by faith in Jesus Christ. Stand in faith believing, and keep your heart open for God to work in your husband's life. Your husband is on his own spiritual journey and God will lead him in the way that is best for him. If your husband truly is to be saved, then God has already chosen him and will reveal himself to him in a way that only God knows is best. Trust in God and his promises. Don't fall into temptation and try to manipulate the situation to come out the way you want it to be. We serve a loving and jealous God and we should trust in his will for our lives.
