This dream seems to reflect concerns and insecurities regarding your relationship with your boyfriend. Let's address the issues and pray together according to God's will.
Firstly, we need to address the fact that you mention you have a boyfriend and not a spouse. It is important to consider what the Bible teaches about relationships. A boyfriend and girlfriend courtship is to prepare for marriage. The Bible teaches about the sanctity of marriage between a man and a woman as a lifelong commitment. It is written, But from the beginning of the creation, God made them male and female. For this cause a man will leave his father and mother, and will join to his wife, and the two will become one flesh, so that they are no longer two, but one flesh (Mark 10:6-8, WEB).
The Bible also teaches to refrain from any sexual relationships before marriage, for this is fornication. Again, sexual relations are only for a man and a woman in marriage. Any other sexual relationship is fornication and is considered immoral. It is written, Flee sexual immorality! Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body (1 Corinthians 6:18, WEB).
When we look at the relationship between your boyfriend and the other woman in the dream, it appears a lack of boundaries may have caused concerns. In a godly relationship leading towards marriage, it is important to honor each other and maintain healthy boundaries. It is written, Let love be without hypocrisy. Abhor that which is evil. Cling to that which is good (Romans 12:9, WEB). This applies to any relationships.
Your dream also shows a lack of peace and contentment. The Bible teaches us to trust in God to give us peace and rest. It is written, Be anxious for nothing, but in everything by prayer and petition with thanksgiving, let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus (Philippians 4:6-7, WEB).
We also notice that you did not mention the name of Jesus Christ in your prayer request. This is a serious concern. It is only through Jesus Christ that we can approach God. It is written, For there is one God, and one mediator between God and men, the man Christ Jesus (1 Timothy 2:5, WEB). This means that prayer should be made in the name of Jesus Christ. For people to be saved they must believe in Jesus Christ as their Lord and Savior. It is written, that if you will confess with your mouth that Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved. For with the heart, one believes resulting in righteousness; and with the mouth confession is made resulting in salvation (Romans 10:9-10, WEB).
Let us pray together for your concerns according to God's will:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up the one who submitted this prayer request. We pray that You will guide ### relationship with her boyfriend in a way that honors You and aligns with Your will. Help them to maintain healthy boundaries and pursue purity in their relationship. We also pray that You will provide her the same peace and comfort that comes only from You.
Lord, if there are any issues in her life that do not align with Your will, we pray that You will reveal them to her and give her the strength to address them. We also pray that You will guide her boyfriend in his relationships and help him to be the godly man You have called him to be. Help them to refrain from sexual immorality and to seek Your will in their lives.
If there is any confusion or misunderstanding about the basic salvation message of believing in Jesus Christ, we ask You to help them understand and believe. We ask You to show them they must turn away from their sin and place their faith in Jesus Christ as their Lord and Savior.
Father, we know that You are a God of mercy and grace, and we trust that You will work in their lives for Your glory. We pray this in Jesus' name.
Amen.
We encourage you to seek God's will in your relationship and to trust in Him to guide you.
