We join you in prayer, seeking God's will for your relationship with your fiancé. It's wonderful that you acknowledge the power of prayer and the need for God's intervention in your relationship. We will look at your requests and respond to them. Already, you have asked in the name of Jesus Christ which is the way that we have access to God according to the Bible.
Firstly, let's address the use of the term "fiancé." In biblical principles, a couple should be moving toward a lifelong commitment in marriage. We encourage you to view this period as courtship, a time to prepare for a godly marriage. We have Scripture that says, "Therefore a man will leave his father and his mother, and will join with his wife, and they will be one flesh." (Genesis 2:24 WEB) and "Nevertheless, each of you should have his own wife at home, and each woman should have her own husband." (1 Corinthians 7:2 WEB) This means that God's design is for a man and a woman to be joined in marriage, not just in a relationship or engagement.
Regarding the chains, you are asking God to break the devil's hold on you, Jesus said, "If therefore the Son makes you free, you will be free indeed." (John 8:36 WEB) The Bible says, "Be sober and self-controlled. Be watchful. Your adversary, the devil, walks around like a roaring lion, seeking whom he may devour." (1 Peter 5:8 WEB) This means you must be aware of the devil's schemes and resist him. You can use the Scripture, "Submit yourselves therefore to God. Resist the devil, and he will flee from you." (James 4:7 WEB)
God can certainly open your eyes to see each other in a new light and soften your hearts towards each other. The Bible says, "A new commandment I give to you, that you love one another. Just as I have loved you, you also love one another." (John 13:34 WEB) This love is not just a feeling but a commitment to act in the best interest of the other person.
Negative thoughts and feelings can be addressed with the Scripture, "Finally, brothers, whatever things are true, whatever things are honorable, whatever things are just, whatever things are pure, whatever things are lovely, whatever things are of good report; if there is any virtue, and if there is any praise, think about these things." (Philippians 4:8 WEB)
Healing from past hurts is important. The Bible says, "Be kind to one another, tenderhearted, forgiving each other, just as God also in Christ forgave you." (Ephesians 4:32 WEB) Forgiveness is key to healing and strengthening your bond.
We pray that you both feel appreciated, loved, and happy within yourselves and with each other. Remember, "Love is patient and is kind; love doesn't envy. Love doesn't brag, is not proud," (1 Corinthians 13:4 WEB)
God can certainly give you the strength, knowledge, mindset, and heart to work things out. The Bible says, "I can do all things through Christ, who strengthens me." (Philippians 4:13 WEB)
Lastly, listening, following directions, and paying attention to each other are crucial. The Bible says, "Therefore as the elect of God, holy and beloved, put on a heart of compassion, kindness, lowliness, humility, and perseverance; bearing with one another, and forgiving each other, if any man has a complaint against any; even as Christ forgave you, so you also do." (Colossians 3:12-13 WEB)
Let's pray together:
Dear Heavenly Father, we come before You, lifting up this couple in prayer. We ask that You guide them in Your will, breaking any chains that the devil may have on them. Open their eyes to see each other in a new light, soften their hearts, and remove any negative thoughts or feelings. Heal them from past hurts and strengthen their bond. Help them to feel appreciated, loved, and happy. Give them the strength, knowledge, mindset, and heart to work things out and to listen, follow directions, and pay attention to each other. We pray for their future marriage, that it would be a godly union that honors You. In Jesus' mighty name, we pray. Amen.
Continue to trust in God, and seek His will for your relationship. Remember, "For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future." (Jeremiah 29:11 WEB)
We encourage you to continue praying together and studying the Bible to deepen your relationship with God and with each other. If there is anything that does not align with biblical principles, always check with the Scriptures. If you should be convicted of anything, repent and turn to God and believe the Gospel. Paul says, "I am not ashamed of the Good News of Christ, for it is the power of God for salvation for everyone who believes." (Romans 1:16 WEB) We pray that you both grow stronger in your faith and in your relationship with each other as you prepare for a lifelong commitment in marriage.
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.
