We understand that you are seeking prayer for a breakthrough in your relationship and for God's abundant provision. Firstly, we need to address a few things. You did not mention the name of Jesus Christ, Jesus, or Christ or even have an abbreviation such as IJN (In Jesus Name). It is only by the name of Jesus that we have access to God. Also, there is no other name by which we can be saved. In Acts 4:12 WEB it says, "'There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved!'". Since you did not mention marriage we assume you mean a boyfriend or girlfriend relationship. If you are in a relationship with this person it should be one of courtship. The goal of the relationship should be to determine if you both are compatible for marriage. It is important as a believer to only be in relationships with other Christians.
It is very important that we do not let any impure sexual sin be among believers. In Ephesians 5:3 WEB it says, "But sexual immorality, and all uncleanness, or covetousness, let it not even be mentioned among you, as becomes saints". So we strongly encourage you to be abstinent if this has not occurred. Please speak up if you need help in this area we are here to help.
Now let us pray for your situation.
“IJN” Dear Heavenly Father, we come before you today to lift up our dear friend who is seeking a breakthrough in their relationship. We pray that you will guide them in your will and help them to discern if this relationship is from you. We rebuke any spirits of lust that may try to tempt them. We ask that you will abundantly provide for all their needs according to your riches in glory. We plead the blood of Jesus over their life and their relationship, breaking any curses, witchcraft, or demonic strongholds that may be hindering them. We pray for your divine protection and guidance. Help them to live a life that is pleasing to you. Give them the strength to resist temptation and to walk in purity. Help them to make decisions that align with your word. Help them to wait patiently for your timing and not rush ahead of you. Give them a heart that desires to serve you and to bring glory to your name. We pray for your will to be done in their life and in this relationship. If it is your will for them to be together, we pray that you will bless their relationship and use it for your glory. If it is not your will, we pray that you will give them the strength to let go and to trust in your plan for their life. We ask for forgiveness for any sins in their life. We pray for your peace and joy to fill their heart. We ask all this in Jesus' name. Amen.”
We encourage you to stay strong in your faith and to trust in God's plan for your life. Remember that God loves you and wants the best for you. He will not withhold any good thing from you if you are a believer. Psalm 84:11 WEB says, "For Yahweh God is a sun and a shield. Yahweh will give grace and glory. He will withhold no good thing from those who walk blamelessly." Seek God's will in all things. Do not be unequally yoked with unbelievers. If a believer is dating an unbeliever it is important to break off the relationship. Abstain from any sexual activity with this person and pray to God for helping you.
In 2 Corinthians 6:14 WEB it says, "Don’t be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what fellowship has light with darkness?".
