We understand that you are seeking a miracle for yourself and your favorite person. We want to lift you both up in prayer, but first, let's remember the words of Jesus in John 14:13-14 (WEB), "Whatever you will ask in my name, that I will do, so that the Father may be glorified in the Son. If you will ask anything in my name, I will do it."
It's important to ask in Jesus' name, as it is through Him that we have access to the Father (Ephesians 2:18). Also, let's pray that this favorite person is or will become a fellow believer in Jesus Christ, as God desires all people to be saved and come to the knowledge of the truth (1 Timothy 2:3-4).
Now, let's pray:
"Dear Heavenly Father, we come before You in Jesus' name, lifting up Anonymous and their favorite person. Lord, we ask for Your divine intervention in their lives. We pray that You will reveal Yourself to them, grant them saving faith if they do not already have it, and work a miracle in their lives according to Your will. Help them to grow in the knowledge of Your Word and to walk in Your ways. We ask this in Jesus' name, for Your glory. Amen."
Remember, God works all things together for good for those who love Him and are called according to His purpose (Romans 8:28). Trust in Him, and He will make your paths straight (Proverbs 3:5-6). Always seek His will and align your desires with His Word. If there is anything not in accordance with His will, He will guide and correct you.
