An Interesting Luther Quote

[A]fter the children of Israel had entered into the land of Canaan, killed absolutely all the kings and destroyed their power, there still remained a natural and genuine part of the annihilated peoples of the Canaanites, Jebusites, and Amorites (as is written in Judges 1). They did not rule, nor were they equal to, the children of Israel, but were tributaries and servants, until at last David, having established the kingdom, wiped them out. So also we, having been called into the kingdom of faith by the grace of baptism, gain the rule over sin, for all its powers are smitten. Now only grumbling remnants, possessing the nature and character of what was destroyed, remain in the members. These we ought to extirpate by our own exertion, but this will happen only when Our David, having established the kingdom, will be enthroned in his majesty.
