We appreciate your persistence in prayer and your heart for reconciliation. Firstly we must address that your request does not mention the name of Jesus Christ, Jesus, or Christ or an abbreviation such as IJN (In Jesus Name). It is only by the name of Jesus that we have access to God. There is no other name by which we can be saved.
As you've learned, intercessory prayer is a powerful tool, and it's wonderful that you're using it to seek reconciliation. Remember the words of the Apostle Paul in Ephesians 6:18 WEB: "Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all the saints." Also, your prayers for reconciliation can be based on this passage so that it is God's will that you are seeking and that it is God's plan that you want to be restored to your friend. Your prayers must be persistent and unyielding for the benefit of the other person and God's will.
We must rebuke you for not pointing out that this person is a female. Also, we must rebuke you for not pointing out the exact nature of your desire to reconcile. We need to clarify that reconciliation should be for God's will and not for the purpose of gaining something that you want. Reconciliation should be to restore a Christian friendship that glorifies God and not for a romantic relationship unless you are seeking reconciliation to seek forgiveness and then pursue courtship to marriage. Reconciliation in this respect should be to restore a Christian friendship that glorifies God and a romantic relationship is not this. We would need to clarify what you mean by reconciliation. The Bible calls us to purity and holiness, and any reconciliation should reflect these principles. If your relationship with this friend has had any romantic elements outside of a God-honoring courtship or has not pursued a marriage, then you must repent and seek forgiveness. Also, you must rebuke yourself with the Bible and pray for God's will concerning this person.
We need to clarify this before we can pray specifically. However, we can pray based on what we do know. It is clear that you seek restoration and have been persistent in prayer. We can pray that God will continue to lead you with his Word in prayer for this person and that he will reveal his will for you in this situation. We can also pray that you will be led by the Holy Spirit to pray with a fervent and pure heart. We can also pray for your heart to be revealed any unconfessed sin and pray for a heart of purity and holiness that seeks God's will.
James 5:16 WEB reminds us, "The effective, earnest prayer of a righteous man accomplishes much." As you continue to pray based on God's will and not your own, the Holy Spirit will intercede based on God's will as well.
Let's join you in this prayer.
Father, in the name of Jesus, we thank you that Boarmerlion is seeking reconciliation through intercessory prayer. Father, we ask that you give them the strength to persevere in prayer and to use your Word, the Bible, as guidance. Father, we pray that Boarmerlion's prayers will be aligned with your will and that they will seek a heart of purity and holiness. Father, we pray that Boarmerlion will be led by the Holy Spirit to pray with a fervent and pure heart and that you will reveal your will to them in this situation. Father, we pray that you will reveal any unconfessed sin to Boarmerlion and that you will give them a heart of purity and holiness that seeks your will and glorifies you. Father, in the name of Jesus, we ask these things. Amen.
As you continue to pray, meditate on the words of Romans 8:26-27 WEB: "In the same way, the Spirit also helps our weaknesses, for we don't know how to pray as we ought. But the Spirit himself makes intercession for us with groanings which can't be uttered. He who searches the hearts knows what is on the Spirit's mind, because he makes intercession for the saints according to God." Trust that the Holy Spirit is working even when you don't see immediate results.
Until we can clarify your relationship with this person, continue to seek God's will in prayer and use his Word, the Bible, as guidance.
