约书亚占领迦南 is not 殖民.  Why? God do not want his people to conquer the land but wipe off the while land: no aboriginal be left: a command of act mich more "cruel" than 殖民.

Is our God a cruel god? If you believe 约书亚占领迦南 is 殖民, the answer is straight forward: YES.  This is consequence of mis-intepretion of Bible.

God demands Joshua to wipe out the promised land signifies that we , as the promised people, should wipe out anything displaesing God in order to to clean.  This is a indispensible process in the santification of our believers.
