Let us begin by addressing the issues present in your request. First, it is important to note that the Bible teaches us to pray in the name of Jesus, as it is through Him that we have access to God. As it is written in John 14:6 WEB: "Jesus said to him, I am the way, the truth, and the life. No one comes to the Father, except through me". And in John 14:13-14 WEB: "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it."
We also need to address the nature of your relationship. You mentioned that you want God to restore your relationship with your partner. In the Bible, the only relationship that is blessed by God is that between a husband and a wife, and any focus should be on courtship for the goal of a godly marriage. As it is written in Hebrews 13:4 WEB: "Let marriage be held in honor among all, and let the bed be undefiled: but God will judge the sexually immoral and adulterers." So we encourage you first to examine the nature of your relationship and ensure it aligns with biblical principles. To be sure, God's will is for you both to be Christians.
Regarding the issues in your relationship, it is important to remember that God wants us to be in peaceful and loving relationships. As it is written in Romans 12:18 WEB: "If it is possible, as much as it is up to you, be at peace with all men." And in 1 Corinthians 13:4-7 WEB: "Love is patient and is kind; love doesn't envy. Love doesn't brag, is not proud, doesn't behave itself inappropriately, doesn't seek its own way, is not easily provoked, and doesn't take account of evil; doesn't rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, and endures all things."
Let us then pray for you both.
Heavenly Father, we come before You in the name of Jesus, seeking Your will and intervention in this situation. We pray that You will convict both of their sins and bring them to salvation and to be baptized. We pray that You will guide them and give them wisdom to be in a relationship that honors You, Lord, a courtship looking towards a godly marriage. We ask that You bless the person who submitted this request to forgive their past and point their life towards your will. We pray for healing and reconciliation between the two people in this situation if it aligns with the Bible. We pray for restoration where possible and for both parties to have hearts that are open and willing to communicate. We pray for any negative thoughts or influences to be removed from their minds and relationship, and we rebuke any evil forces that may be at work, for it is written in James 4:7 WEB: "Be subject therefore to God. But resist the devil, and he will flee from you." We ask for a hedge of protection around them, to shield them from harmful influences. We pray that Your will be done in their lives and that they will always seek first Your Kingdom and righteousness.
Finally, we encourage both of you to be an example of Christ even in this situation. Godly interactions and honesty will establish trust. This is not an opportunity to be deceitful or dishonest. As it is written in Proverbs 12:22 WEB: "Lying lips are an abomination to Yahweh, but those who do the truth are his delight."
We trust that God will work in your lives and that His will shall be accomplished.
