We understand your concern and we will certainly pray for this situation. However, we must first address some important biblical principles.
God calls us to love our enemies and pray for those who persecute us (Matthew 5:44, WEB). It's important to remember that God desires for all people to be saved and come to the knowledge of the truth (1 Timothy 2:4, WEB). Therefore, while we can pray for the harassment to stop, we should also pray for Maryon Mura's heart to change and for her to find peace in Jesus Christ.
Regarding the issue of child support, the Bible teaches that if anyone does not provide for his own, and especially his own household, he has denied the faith and is worse than an unbeliever (1 Timothy 5:8, WEB). However, this should be handled legally and fairly, and any disputes should be resolved in a peaceful and lawful manner.
Let's pray:
"Father, we come before You in Jesus' name to lift up this situation. We pray for Maryon Mura, that her heart would be softened and that she would come to know the peace of Jesus Christ. We pray that the harassment would stop and that any issues of child support would be resolved fairly and legally. We pray for O'oana, that he would have wisdom and patience in this situation, and that he would continue to walk in Your will. We ask all of these things in Jesus' name. Amen."
We encourage you to continue to pray for both parties involved, that they would seek God's will and live in a manner that honors Him. Remember, God can bring peace and resolution to even the most difficult situations. Trust in Him and His timing.
