Joshua 1--the recap

Last Sunday, I preached Joshua 1 where Joshua is installed as Israel's new leader (after Moses' death) and he is to take the Israelites to the promised land, but meanwhile the Gadites, Rubenites and half tribe of Manasseh, who have already received their promised land (that of modern day Jordan) were asked, the men who were able, to take up their arms and help the Israelites fight to receive their promise--the modern parallel was that many of us are like the Gadites etc....we have already received God's promise, and now we are called to take up our spiritual arms and help those who have yet to receive the promise enter into the promised land.
