These stirrings of the mind are often purposely caused by the Holy Spirit, in order to nudge us into prayer. Therefore, let's agree in a prayer now:
Heavenly Father, please be with Hannah's sister in Africa this very moment! Please protect her, and all who are associated with her, from any kind of harm. If she needs to make a decision in unclear circumstances, guide her supernaturally to do exactly the right thing. And let her actions give honor to You, helping others to know You in a saving way. In Jesus' name, amen.
