The kingdom Gospel of Daniel 2:44 'IS' preached to the world just as Jesus said to do at Matthew 24:14; Acts 1:8.
In other words, because remote translation offices have made rapid Bible translation possible to the people living in remote areas thus they now have Scripture in their own mother tongue or native language.
Plus, video has now made 'sign language' preaching possible all over the world.
The preaching of this Gospel of the Kingdom will be done in its purity. This cannot happen until the wise have one gospel, one shepherd.
