This is my 3:15 PM (Prayer Model). Pray for 3 minutes, once a day, for 5 children. I believe that God will save one or more of those children even though we don’t have names or places to be specific about.
Of course, this is a model, a starting point, you can pray however the Holy Spirit leads you. It's less important how you pray than that you pray. I believe that God cannot change the situation without our prayers.
Ask God to save one child who has never been abused from being molested – to literally stop an abuse that is about to happen, and to protect that child from any further attempts at abuse.
Ask God to deliver one child who is being abused at this very moment from its abuser, and to protect that child from any further attempts at abuse.
Ask God to deliver one child from chronic sexual abuse like child marriages or forced prostitution. To break her bonds whether they are physical, emotional, chemical or psychological, and give her the courage and opportunity to escape. Ask God to direct her steps to the help she needs to fully recover.
Ask God to stop one little girl from becoming a child bride.
Ask God to save one little girl from the horror of female circumcision.
If you have the faith pray for 100 children rather than one.
Thank Him for hearing our prayers.
Other matters we should pray about:
Ask God to deliver the men involved with these girls from the evil they commit and save them if at all possible. If that is not possible, then ask the Lord to do what He has to do to stop them from committing further abuse.
Pray for cultural changes in populations where girls are seen as burdens and are treated as sexual toys by men.
Pray for the billions of sexually abused children and adults to be set free from the bondage of their abuse, and brought into a healthy relationship with Jesus Christ.
Pray against the poverty that is so severe in so many countries that parents sell their little girls to grown men for marriage or outright prostitution.
Pray for governments, the police, and the courts to become far more sympathetic to child sex abuse victims, and much more protective of our children.
Pray for a way to eliminate child pornography.
Pray for a way to end the 'Rape Culture' that is so prevalent in our universities and elsewhere. This may require an end to, or difficulty accessing, pornography for adolescents.
Ask God what you can do to help.
