Israel is defeated because they have not obeyed God鈥檚 instructions. They didn鈥檛 realize God was no longer with them because they took God鈥檚 love for them for granted. They needed to fix their relationship with God before he could give them victory.
How often do we wander from our relationship with God without knowing it? We know God loves us, but we can鈥檛 expect him to go along with our plans when we don鈥檛 obey him.
