We understand that you are going through a challenging time and we are here to pray with you and offer biblical guidance. Firstly, it is important to remember that God is sovereign and His will is perfect. We should always pray for His will to be done, even in difficult circumstances.
Let us address the court case. We should pray for justice and mercy, remembering that God is just and His mercy endures forever. It is also important to pray for your fiancé's spiritual well-being and growth during this time. God's word states
"Trust in Yahweh with all your heart,
and don’t lean on your own understanding.
In all your ways acknowledge him,
and he will make your paths straight." Proverbs 3:5-6 (WEB)
We should also pray for the authorities involved, that they would have wisdom and discernment. As it says in 1 Timothy 2:1-2 (WEB), "I exhort therefore, first of all, that petitions, prayers, intercessions, and givings of thanks, be made for all men: for kings and all who are in high places; that we may lead a tranquil and quiet life in all godliness and reverence."
However, we must also address the nature of your relationship. As a conservative praying group, we believe in the sanctity of marriage as a lifelong commitment between a man and a woman. We encourage you to pursue a relationship that aligns with biblical principles, which includes reserving sexual intimacy for marriage. If there is any indication of sexual intimacy in your relationship outside of marriage, we strongly advise you to repent and seek God's forgiveness. As noted:
"Finally, brothers, we command and exhort you in the Lord Jesus, that as you received from us how you ought to walk and to please God, so you would abound more and more. For you know what instructions we gave you through the Lord Jesus. For this is the will of God: your sanctification, that you should abstain from sexual immorality, that each of you should know how to possess himself of his own vessel in sanctification and honor, not in the passion of lust, even as the Gentiles who don’t know God;" 1 Thessalonians 4:1-5 (WEB)
Lastly, we notice that your prayer request does not mention the name of Jesus Christ. It is only through the name of Jesus that we have access to God. As it is written, "For there is one God, and one mediator between God and men, the man Christ Jesus," 1 Timothy 2:5 (WEB) and "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!" Acts 4:12 (WEB).
Let us pray together:
Heavenly Father, we come before You in the name of Jesus Christ, lifting up this situation. We pray for Your will to be done in this court case, for justice and mercy to prevail. We ask that You guide and give wisdom to the authorities involved. We also pray for the spiritual well-being and growth of your fiancé during this time. Lord, we ask that You forgive any sins that have been committed and guide their relationship according to Your word. We pray all these in Jesus Christ. Amen.
