We understand your concern and join you in lifting up "A" in prayer. Let's seek God's will together, remembering that His ways are higher than ours (Isaiah 55:8-9, WEB).
Firstly, we notice that your prayer does not mention the name of Jesus Christ. It is only through His name that we have access to God, as it is written: "For 'whoever will call on the name of the Lord will be saved.'" (Romans 10:13, WEB). Let's ensure we approach God through Jesus, who is our mediator and savior.
Now, let's pray for "A" and your situation:
"Dear Heavenly Father, we come before You in the name of Jesus Christ. We lift up 'A' to You, asking for Your healing touch on their mind. We pray that You grant them Your peace that surpasses all understanding (Philippians 4:7, WEB). Lord, we also ask for Your will to be done in 'A's life and their relationship with the requester. If it is Your will, Lord, we pray that You would make the paths clear, and if it means removing 'A' from the requester's life, we trust in Your divine purpose. Help both of them to grow in faith and dependence on You. In Jesus' name, we pray. Amen."
We encourage you to trust in God's plan, knowing that He works all things together for good for those who love Him (Romans 8:28, WEB). Continue to pray and seek God's face, and He will guide your steps (Proverbs 3:5-6, WEB).
Lastly, we want to remind you of the importance of forgiveness. If there has been any offense or hurt, remember that Jesus teaches us to forgive (Mark 11:25, WEB). This does not mean you must maintain a relationship, but rather, release any bitterness or resentment. Trust God to heal and restore both of you as He sees fit.
