Let us first address the concern about your fiancé. We must remember that our battle is not against flesh and blood, but against the rulers, against the authorities, against the world rulers of this darkness, and against the spiritual forces of evil in the heavenly places. In Ephesians 6:12 WEB it says For we do not wrestle against flesh and blood, but against the principalities, against the powers, against the world's rulers of the darkness of this age, and against the spiritual forces of wickedness in the heavenly places. We can certainly pray for God's protection and intervention in his life. However, it is important to note that changes in behavior could also be due to natural causes and not necessarily witchcraft. We should pray for wisdom and discernment to understand the root of the issue.
Let us pray:
Dear Heavenly Father, we come before You in the name of Jesus Christ, lifting up the fiancé of Qayhaven. Lord, we pray for Your divine protection over him and their relationship. If there are any spiritual influences affecting his behavior, we rebuke them in Jesus' name and ask that You remove them. Guide them both with Your wisdom and discernment to understand the root cause of his behavioral changes. Help them to communicate openly and honestly with each other, and to support each other in love and patience.
Father, we also pray for his provision. Open the doors for him to find a good job so that they can plan their wedding and build a life together that honors You. Guide them in their courtship towards a Godly marriage and away from temptation. Let them flee from sexual immorality. Every other sin a person commits is outside the body, but the sexually immoral person sins against his own body. Or do you not know that your body is a temple of the Holy Spirit within you, whom you have from God? You are not your own, let them remember that they were bought with a price. So glorify God in their body.
We ask all of this in the powerful name of Jesus Christ, who is the only way to You, Heavenly Father. It is by his name and his sacrifice on the cross for our sins that we are saved. For there is no other name under heaven, given among men, by which we must be saved.
As for you, Qayhaven, we encourage you to trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths. Stay strong in your faith and continue to pray for your fiancé. Remember that God is faithful, and He will not let you be tempted beyond your ability, but with the temptation He will also provide the way of escape, that you may be able to endure it.
Stand firm in the love of Christ, and may God bless your journey together. If there is anything not aligned with God's will in your relationship, then pray for God to either change the circumstances or give you both the strength to walk away from it.
