God wants to give us stolen goods?

Deuteronomy 6:10 says, “And it shall be, when the LORD thy God shall have brought thee into the land which he sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give thee great and goodly cities, which thou buildedst not,

6:11 And houses full of all good things, which thou filledst not, and wells digged, which thou diggedst not, vineyards and olive trees, which thou plantedst not; when thou shalt have eaten and be full;”  Who built these cities?  Who dug these wells?  If they were done by someone else.  Where did they go?  Why would god have to kill people to save his people work.  Doesn’t god love all of us?  Before you say they displeased him think about what you would do to people who displease you.  Would you kill them and then steal their stuff?  The christian’s loving god obviously would.  So far he scares me.  Remember.  He is living with the Israelites and that is the only thing keeping them on the road to salvation.  The people god killed didn’t have him living in their midst.  He must not have liked them to much.
