We understand your urgency and desire to see significant changes in ###'s life and your relationship together. Firstly, we commend you for asking in Jesus' name, as it is only by His name that we have access to God and salvation. As it is written:
Acts 4:12
There is salvation in none other, for there is no other name under heaven that is given among men by which we must be saved!
It is by the name of Jesus Christ that you can ask for such important things to happen, but our concern is that you may be asking less for ###'s salvation and spiritual growth and more for your own desires. However, this can happen once ### makes a change.
1 John 5:14-15
This is the confidence which we have before him, that, if we ask anything according to his will, he listens to us. And if we know that he listens to us, whatever we ask, we know that we have the petitions which we have asked of him.
Romans 10:9-10
because, if you 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 man believes resulting in righteousness; and with the mouth he confesses resulting in salvation.
We will pray for ###'s salvation and for God's will to be done in his life, including the destruction of any idolatry or false beliefs, as you requested. However, we must also caution you about your requests regarding your relationship with ###. If you are currently married to ###, this will be our response:
It is God's will to flourish a godly marriage between a man and a woman, both living and committed to following Christ. In biblical sense if ### has already been with you in a physical intimate way such as physical premarriage sex, even if it was mutual and consensual if is still called fornication and is a sin. ### would need to repent of this behavior and should save sexual intimacy for marriage. This does not mean however, that ### must become your husband and marry you. He should ultimately seek a marriage with a Christian woman if he does.
Ephesians 5:3
But sexual immorality, and all uncleanness, or covetousness, let it not even be mentioned among you, as becomes saints.
1 Corinthians 6:18
Flee sexual immorality! Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body.
If you are not currently married you might also consider reserving some intimacy and closeness for marriage with your spouse. However, we understand you may have special close feelings and how you might desire to strengthen this heartfelt connection you have with ###. The correct view and the biblical indication are:
Romans 12:1-2
Therefore I urge you, brothers, by the mercies of God, to present your bodies a living sacrifice, holy, acceptable to God, which is your spiritual service. Don't be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good, well-pleasing, and perfect will of God.
Furthermore, it is important to note that while God can change hearts and bonds we are cautious of how you requested no ties to other potential spouses except you without considering ### completely having a choice. We must remember that God gives free will and especially now ### should only remain in a relationship with you to serve the Lord. ### should only have one spouse and if he desires to break a relationship with you, that is allowed under God's will.
Corinthians 7:39
The wife is bound by the law as long as her husband lives; but if her husband is dead, she is free to be married to whom she wishes, but only in the Lord.
The rest in Jesus name, and His shed blood and authority for a hedge of protection in the whole relationship and marriage only applies if you are both married and both saved believers in Christ. In the event you are both doing God's will, married and believing in Him we can pray for protection around you both.
Let us pray:
Dear Heavenly Father,
We come before You in Jesus' name, lifting up ### and ###. We ask, Lord, that You reveal Yourself to ###, that the allure of any false beliefs would be broken, and that he would come to know Jesus Christ as his Lord and Savior in a deep and meaningful way. We pray that You would melt his heart and draw him closer to You, that the we all would know Your will in this situation. We pray for forgiveness from any fornication as defined in your Word.
We ask if it pleases you that you would unite two Christian believers in a marriage that will be a showcase of your covenant and love. Provide a strong hedge of protection around their relationship if they are a spouse and a spouse, guarding them from any attacks or negative influences. Ultimately, this is only if they are both in your will and you desire this of them. Strengthen their bond, and help them to grow together in faith and love. We come against and bind any evil object that may be against them and presenting this relationship from coming into fruition. We declare no weapon formed against ###, ###, or their relationship will prosper if and only if it pleases you and is your will.
We ask that You would bless their relationship and give them both pure hearts, wisdom, and discernment to follow You and only You if this can occur in a marriage. We ask that they be equally yoked to serve you as a team. In Jesus' name, we pray believing that your will is done through this prayer and the declaration of our mouth and in the words of our biblical text.
Amen.
Let's remember, God's mercy is boundless. "Nothing can separate us from the love of God" (Rom 8:38-39). Suicide is a tragedy, not a condemnation. God understands our deepest pain. "He heals the brokenhearted and binds up their wounds" (Ps 147:3). Trust His love & pray for healing. In Jesus' name!
