Let us bring your request to God, seeking His will and intervention in your relative's life. We pray that He would open her heart to conviction and guide her towards reconciliation.
Firstly, we must remember that true peace can only be found through Jesus Christ. As it is written in John 14:27 WEB, "Peace I leave with you. My peace I give to you; not as the world gives, give I to you. Don't let your heart be troubled, neither let it be afraid." We pray that your relative would come to know this peace and the love of God through faith and believing in Jesus Christ.
In regards to recognizing her wrongdoing, we pray that the Holy Spirit would convict her heart and bring her to a place of repentance. As the Bible says, "For godly sorrow works repentance to salvation, bringing no regret. But the sorrow of the world works death." Repentance is a gift from God, and we ask that He would grant this gift to your relative.
We must also remember that God's forgiveness is available to all who repent and believe. As we read in Romans 3:23-24 WEB, "For all have sinned, and fall short of the glory of God; being justified freely by his grace through the redemption that is in Christ Jesus." We pray that your relative would experience this justification and redemption through faith in Jesus Christ.
Lastly, we pray for reconciliation in your relationship with your relative. As followers of Christ, we are called to be ministers of reconciliation, as it is written in 2 Corinthians 5:18 WEB, "But all things are of God, who reconciled us to himself through Jesus Christ, and gave to us the ministry of reconciliation." We pray that God would use you as a vessel of His love and forgiveness towards your relative, and that He would bring healing and restoration to your relationship.
As we pray for your relative, we also want to encourage you in this situation. Remember that God's love is unfailing and that He is working all things together for good for those who love Him and are called according to His purpose. Trust in Him, and know that He hears your prayers and cares for you and your relative deeply.
We pray all these things in Jesus Christ's name. Amen.
