Anyone who actually thinks that all of His enemies have been destroyed do not have a grip on reality.
Do they really think that this has already happened?:
"The Lord at thy right hand shall strike through kings in the day of his wrath. He shall judge among the heathen, he shall fill the places with the dead bodies; he shall wound the heads over many countries" (Ps.110:5-6).
Do they really think that the following prophecy has already been fulfilled?:
"Behold, the day of the LORD cometh, and thy spoil shall be divided in the midst of thee. For I will gather all nations against Jerusalem to battle; and the city shall be taken, and the houses rifled, and the women ravished; and half of the city shall go forth into captivity, and the residue of the people shall not be cut off from the city. Then shall the LORD go forth, and fight against those nations, as when he fought in the day of battle. And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east" (Zech.14:1-4).
I challenge anybody to tell us when this prophecy was fulfilled in the past!
