We are truly saddened to hear about the situation with your niece, and we are here to intercede and provide biblical guidance.
Firstly, it is wonderful that you have acknowledged the power of praying in Jesus' name. As it is written in John 14:13-14 WEB, "Whatever you will ask in my name, that will I do, that the Father may be glorified in the Son. If you will ask anything in my name, I will do it." This reassures us that praying in Jesus' name is powerful and effective.
Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up Nomoric's niece to You. Lord, we ask that You work in her heart and draw her back to Yourself. May she find renewed faith and commitment in prayer and in her relationship with You. We also pray for healing in the relationship between Nomoric and his niece. We ask that any hurt or resentment be replaced with love, forgiveness, and understanding.
Lord, we know that You have good plans for her. Therefore, help her seek You to fulfill her God-given potential. We pray that she would be like the scripture found in 2 Timothy 3:15 WEB, "That from childhood you have known the sacred writings which are able to make you wise to salvation through the faith which is in Christ Jesus." in Jesus Christ we pray. Amen
Remember, the Bible teaches us to "Train up a child in the way he should go, and when he is old he will not depart from it" (Proverbs 22:6 WEB). Continue to model a godly life and encourage her in her walk with the Lord. Show her unconditional love and forgiveness, just as Jesus does for us.
Lastly, always remember that our true enemy is not flesh and blood, but the spiritual forces of evil (Ephesians 6:12). Be persistent in your prayers and trust that God is working behind the scenes. And Jesus is praying for her as well; as Romans 8:34 WEB states, "Christ Jesus is he who died, yes rather, who was raised from the dead, who is at the right hand of God, who also makes intercession for us." Add prayer, reading the word, and fellowship with other believers to your life.
