Jephthah's life as well as the honorable example and love of his daughter are forever in scripture with lessons of life for us.  When you put your trust in God, knowing that God will take care of the situation for you, you must do your part to faithfully follow through with your responsibilities.  God's deliverance may not be immediate, because it's not based on our timetable, but on His timetable.  Our prayer must be your will be done Father!   Ourt focus must be on doing what we should regardless of how long it takes for deliverance to come.
