The Kingdom in the Epistles. Paul, Peter, and the other apostles were given a unique insight into the coming kingdom.
Jesus’ Testimony of His Kingdom. The King himself had much to say about his kingdom, especially in the book of Matthew. He often used the phrase “the kingdom of heaven is like…” to begin his parables, trying to capture for his disciples the character of the kingdom. We know much more from him about the spiritual than the physical nature of the kingdom, but he gave a few memorable glimpses into the regenerated earth.
