We understand your urgency in wanting your husband to become a born-again Christian. It's commendable that you desire to see him come to faith in Jesus Christ. Remember, it is the Holy Spirit's role to draw people to Christ.
Conversion is between the individual and God. However, we can pray and be a Godly example for them.
Let's pray together:
"Father in heaven, we come before You in the name of Jesus Christ, lifting up this beloved sister and her husband. Lord, we ask that You soften his heart and draw him to Yourself. Grant him the gift of faith and repentance, that he may be born again and become a new creation in Christ. Help this wife to be a shining light of Your love and grace. Give her wisdom on how to love and pray for her husband during this season. Please bring him to salvation and faith in Jesus Christ. In Jesus Name we pray. Amen."
Let us be a Godly example for our spouses as Paul writes in 1 Corinthians 7:16 WEB: 'For how do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife?'
Let us trust God with our spouses.
Also, remember to walk in Love with your husband and the Lord as written in Proverbs 31:10-12 WEB: 'Who can find a worthy woman? For her price is far above rubies. The heart of her husband trusts in her. He shall have no lack of gain. She does him good, and not harm, all the days of her life.'
We encourage you to continue to be the godly wife you're called to be, trusting that God is at work in your husband's life.
