John 16, 12-15
Jesus said to his disciples: I have much more to tell you, but you cannot bear it now. But when he comes, the Spirit of truth, he will guide you to all truth. He will not speak on his own, but he will speak what he hears and will declare to you the things that are coming.
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.
So, the gospel of the kingdom must first be spread throughout the world, that is, the new word of the son of man must be spread before the end comes.
