We understand your urgency and desire for unity and growth in your marriage. It's commendable that you're seeking God's intervention in your relationship. Let's pray and seek God's will together.
Firstly, it's important to remember that God's desire is for husbands and wives to be one, as stated in Genesis 2:24 (WEB), "Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh."
However, it's crucial to understand that we cannot force someone to become a born-again Christian. It's the work of the Holy Spirit to draw people to Christ. As it says in John 6:44 (WEB), "No one can come to me unless the Father who sent me draws him, and I will raise him up in the last day."
Your role is to pray for your husband, live out your faith in a way that's attractive and compelling, and trust God to do the rest. As it says in 1 Peter 3:1-2 (WEB), "In like manner, wives, be in subjection to your own husbands; so that, even if any don't obey the Word, they may be won by the behavior of their wives without a word, seeing your pure behavior in fear."
Regarding your prayer for unity and deeper love, we pray that God will bless your marriage and draw you both closer to Him and to each other. As it says in Ecclesiastes 4:12 (WEB), "Though one may be overpowered, two can defend themselves. A cord of three strands is not quickly broken."
Let's pray:
Dear Heavenly Father,
We come before You in Jesus' name, lifting up this marriage. Lord, we ask that You would draw ### to Yourself, that he would encounter the life-changing power of Your Spirit. We pray for unity in this marriage, that both would be one in mind, body, and spirit.
We ask that You would bless every aspect of their relationship, that their love would grow stronger and more passionate each day. We pray for protection over their marriage, that it would be a testimony of Your love and faithfulness.
Help them to desire only each other, and to live in a manner that is pleasing to You. May Your Word always be in their hearts and minds and may they never depart from it. In Jesus Christ's name, we pray. Amen.
