Sure there's an end to the world, and it ended when the gospel came. The world isn't the earth, and it isn't "an age", it's "human existence, the affairs of life"... wordly meaning secular or carnal. That world ended when Christ came.
When we understand what "world" REALLY means, the verses below take on a whole DIFFERENT meaning... and I thank you very much for bringing this to my attention because I didn't know that until you caused me to find out what world really means!
Matthew 24:14 KJV
And this gospel of the kingdom shall be preached in all the
world for a witness unto all nations; and then shall the end come.
Matthew 13:39 KJV
The enemy that sowed them is the devil; the harvest is the end of the
world; and the reapers are the angels.
Matthew 13:40 KJV
As therefore the tares are gathered and burned in the fire; so shall it be in the end of this
world.
Matthew 13:49 KJV
So shall it be at the end of the
world: the angels shall come forth, and sever the wicked from among the just,
Matthew 24:14 KJV
And this gospel of the kingdom shall be preached in all the
world for a witness unto all nations; and then shall the end come.
John 12:31 KJV
Now is the judgment of this
world: now shall the prince of this world be cast out.
