We understand that you're facing challenges in your relationship, and we're here to pray with you and offer biblical guidance.
Firstly, we commend you for acknowledging God's will in your relationship. It's crucial to remember that God's design for a relationship is that it should be between a man and a woman with the goal of marriage, if single. If you are married then God expects a lifelong commitment and union between a man and a woman.
We are admonished to be equally yoked with unbelievers. For what fellowship has righteousness with unrighteousness? And what communion has light with darkness? 2 Corinthians 6:14 WEB
Since you mentioned a boyfriend and not a spouse, we need to address that first before discussing anything else. First, we need to make sure you are a Christian. Then we need to make sure your boyfriend is a Christian. If not, your priorities need to change immediately.
The Bible is clear that we should not be unequally yoked. That means do not be in a serious relationship with someone who is not a Christian. God desires that we be with a Christian. This is more important than any other desires.
Therefore, let us pray for you to have a godly spouse who loves and serves the Lord with all their heart.
If you are indeed a Christian and your boyfriend is also, then we can address the other issues you mentioned. We need to be clear that a boyfriend should have the intent of seeking marriage, a lifelong goal of being married. If not, then they should have no involvement physically with you and you should have no physical involvement with them.
It is apparent that there are some issues to work through. Trust is a vital component of any relationship, and it's something that should be continually cultivated. Remember, "Love is patient and is kind; love doesn't envy. Love doesn't brag, is not proud," 1 Corinthians 13:4 WEB. Trust is built over time through consistent actions and open communication.
Regarding faithfulness, it's important to note that sexual intimacy is a gift from God designed for marriage. If you are a Christian, fornication and adultery are serious sins that God warns us against. "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. Praying for faithfulness should include praying for purity until marriage.
Let's pray together:
Dear Heavenly Father,
We come before You, lifting up our sister in Christ, and asking for Your will to be done in her relationship. If her boyfriend is not a Christian, we pray that you will bring a godly spouse into her life that loves you with all their heart. We pray that you give guidance and clarity about this relationship. We pray for trust to be strengthened and for both parties to be drawn closer to You and to each other, as is fitting for a couple seeking to glorify God. We pray for purity, that they would remain abstinent until marriage, and that their love would be a reflection of Your love for the church.
In Jesus' name, we pray. Amen.
May God guide you both and grant you the wisdom and strength to follow His will. Keep praying and seeking His face. God bless you.
