The gospel of Jesus Christ as contained in the Bible has sufficiently been preached to all nations. This does not mean, however, that every different denomination of Christianity has to be established in all the world as some suppose, no, and neither does the scripture say that, only that the gospel as contained in the Bible would be preached, and it has been. This is a testament to the time of the end.
The problem is that most people are still – and are ONLY looking for some fellow to show up and save them from the misery of this mortal existence, when in fact, the Second Coming of Christ has already occurred.
