We understand that you're going through a challenging time in your marriage, and we want you to know that we're here to pray with you and offer biblical guidance. Firstly, let's pray:
Heavenly Father, we come before You in the name of Jesus Christ, lifting up this marriage that is going through a difficult crisis. We pray for Your healing power to restore their love and commitment to each other. We ask for the Holy Spirit to remove all doubts and confusion, and to guide them in Your truth. We pray for Your strength to sustain them and help them keep the promises they made to each other. In Jesus' name, we believe and ask this. Amen.
We commend you for your intentions to remain faithful to each other and to keep the promises made in your marriage. As it is written in Malachi 2:14-16 WEB:
"Yahweh has testified against the daughter of Zion, and has uttered his voice from Jerusalem; and the heavens and the earth have heard and been witnesses to the same: and there is yet one with whom I may be allied, even Yahweh: and I have sent the wife of my covenant to him who was to be her companion for life. Did not he make you one, although he had the residue of the Spirit? Why, then, did he make you one? He sought a godly family. Be watchful, then, over your spirit, and do not act treacherously against the wife of your youth. For," says Yahweh, the God of Israel, "I hate divorce; and him who covers his garment with violence!" says Yahweh of Armies; "Therefore pay attention to your spirit, that you do not act treacherously."
God hates divorce, and His desire is for husbands and wives to be committed to each other for life. It is clear that both of you (being a married man and woman) are experiencing doubts. In times like these, it's crucial to remember that God should be at the center of your marriage. Draw near to Him, and He will draw near to you, James 4:8 WEB.
However, we noticed that you did not mention the name of Jesus Christ in your prayer. It is only through His name that we have access to God and salvation. As it is written in Acts 4:12 WEB:
"There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
We encourage both of you to diligently seek the Lord Jesus Christ together, praying in His name, and studying His word. As you grow closer to Him, you will also grow closer to each other. Consider spending time daily in prayer and reading the Bible together. If there is any sin that needs to be confessed either from the past or present, do so to one another and the Lord, so that you may continue to grow in your relationship with Jesus Christ. We also encourage you to seek out a Bible-believing church where you can find fellowship and support.
Lastly, we want to leave you with these encouraging words from 1 Corinthians 13:4-8 WEB:
"Love is patient and kind; love doesn't envy. Love doesn't brag, is not proud, doesn't behave itself inappropriately, doesn't seek its own way, is not provoked, takes no account of evil; doesn't rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things. Love never fails."
Stand firm in these truths, and trust in the Lord to guide you through this challenging time. Continue to be faithful to your marriage, God will get you through this.
