We understand your concern and we empathize with your desire for all prayers to be heard and answered. Firstly, we want to remind you that God is sovereign and He hears every prayer, even those that might not be publicly visible. As it is written in 1 Peter 3:12 (WEB), "For the eyes of the Lord are on the righteous, and his ears open to their prayer; but the face of the Lord is against those who do evil."
However, we want to address something important. We noticed that your prayer request does not mention the name of Jesus Christ. It is only by the name of Jesus that we have access to God the Father. As it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father except through me.'" And in Acts 4:12 (WEB), "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."
So, let us pray together in Jesus' name for all the prayers that are lifted up to God, whether publicly seen or not:
Dear Heavenly Father,
We come before You in the mighty name of Jesus Christ, Your Son. Lord, we lift up all the prayers that have been deleted or gone unseen by human eyes. You, Lord, see and hear all. You are El Roi, the God who sees. We ask, Father, that You answer these prayers according to Your will. We claim the promise in 1 John 5:14-15 (WEB), "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."
Father, we also pray for the person who submitted this request. Open their heart more to the knowledge of Jesus Christ. Help them understand that it is through Jesus alone that we can come to You.
In Jesus' name, we pray. Amen.
We encourage you to always pray in Jesus' name, as it is the key to accessing God's throne of grace. Keep praying and trust that God hears and answers every prayer according to His perfect will.
