I don't think you have ever read the bible with complete comprehension, maybe just bits and pieces of it. Because if you had ever read the whole thing, with a clear head, you would know that first off, only when the israelites did not heed fully to God's advice did they begin to encounter problems. When they killed. God did not tell them to kill, they wanted to kill. God told them they were murderous, stiff-necked and hardened. that is what God told them time and again. After the Exodus, within the very first battles where God led the hebrews, with Joshua at the lead of their army, they were told to smite their enemies, in fact to kill all of them and leave not even their cattle alive. They did not do that. They chose instead let some live, take women and children, whatever. After that, God refused to lead them. It was never God's original plan. It was a sequence of events where the hebrews did not do as God wanted them to do, and thus they suffered the consequences, and are still fighting today in the middle east. The entire bible is the story of man's failure time and time again, to heed God's advice. And God trying time and time again to make things right even in the face of their disobedience, faithlessness and selfishness.

God has never been inconsistent, in his love for his people, in his promises. Read the book without hatred in your heart and you might gleen some insight about how man is murderous and inconsistent. God keeps forgiving and keeps trying to make things right.

It's amazing you are a teacher and have never comprehended the main plot. I am glad you don't teach my kid. God only knows what kind of misconstrued lessons she'd learn about anything.
