We have read your request and we want to seek the Lord together with you about this matter, though the wording is not entirely clear to us. We understand you are asking for a nullification concerning participation and non-participation of many people, and you feel entitled to ask this on behalf of another, and you desire that the matter be rendered void before the Lord as belonging to no one and proven by Bible verses.
We want to gently correct and encourage you from Scripture. We come before God not on the basis of our own entitlement, but in humility and grace. The Word tells us God opposes the proud, but gives grace to the humble James 4:6. We are not entitled to demand that God void or nullify things according to our will, but we are invited to ask according to His will. This is the boldness which we have toward him, that if we ask anything according to his will, he listens to us 1 John 5:14. We also trust in the Lord with all our heart, and do not lean on our own understanding. In all our ways we acknowledge him, and he will make our paths straight Proverbs 3:5-6.
We also must address that we cannot spiritually nullify the participation or free will of an entire population or declare before God that something belonging to Him belongs to no one. The earth is the Lord's, with its fullness, the world, and those who dwell therein Psalm 24:1. All things belong to Him and He is sovereign over all. Each person is accountable before God and has been given responsibility for their own choices, and we are called to pray for all people rather than to void their part. We exhort therefore, first of all, that petitions, prayers, intercessions, and givings of thanks be made for all men, for kings and all who are in high authority, that we may lead a tranquil and quiet life in all godliness and reverence 1 Timothy 2:1-2. God desires all people to be saved and come to full knowledge of the truth 1 Timothy 2:4, not that their involvement be rendered meaningless.
We also notice your request mentions the Lord but does not mention Jesus Christ. We want to lovingly remind you that it is only through Jesus that we have access to God. Jesus said, I am the way, the truth, and the life. No one comes to the Father, except through me John 14:6. 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 Acts 4:12. If we would see our prayers heard and our lives made right with God, we must come through faith in Jesus Christ, believing that He died for our sins and rose again, and confessing Him as Lord Romans 10:9.
Therefore we will pray together not to demand a nullification by our own authority, but to submit this burden to God's perfect will and wisdom, asking Him to bring clarity and truth and to let His purpose stand.
We pray together, Heavenly Father, we come before You in the name of Jesus Christ Your Son. We humble ourselves before You and confess that we are not entitled in ourselves, but we come by Your grace and mercy. Lord, we lift this person and this confusing and heavy matter to You. You know what is meant even when words are unclear. We ask that Your will be done and not ours. We ask that You reveal truth and expose any confusion, and that You help us not to be conformed to this world, but to be transformed by the renewing of our minds, so that we may prove what is the good, well-pleasing, and perfect will of God Romans 12:2. Father, we pray for the entire population mentioned, that You would draw each heart to Yourself, that none would be void or counted as belonging to no one, but that all would know they are Yours and accountable to You. We pray for the owner of this matter and for his mother, that You would cover them with Your peace and guidance, and that any burden that is not theirs to carry would be released to You. We ask that You teach us to pray and cry out according to Your Word and not according to our own feelings of entitlement. We ask this in the mighty and only saving name of Jesus Christ, our Lord, Amen.
We encourage you to continue to seek God in humility through His Word, to test every request by Scripture, and to bring every matter to Him through Jesus. If there is a specific situation weighing on you or on this family, we encourage you to share it more clearly so we can pray more specifically according to God's will.
