Doug your statement divides the gospel into different messages for different times, but Jesus never taught that. Jesus preached one gospel, and He said it was for all nations and for all time. He called it “the gospel of the kingdom,” and He never said it would expire, pause, or be replaced. Jesus said, “The time is fulfilled, and the kingdom of God is at hand. Repent, and believe in the gospel” (Mark 1:15). That same call to repent, believe, and follow Him is repeated after His resurrection, not withdrawn. When Jesus sent the twelve out the final time, He did not tell them the message would later become wrong. He said, “Go therefore and make disciples of all the nations… teaching them to observe all things that I have commanded you” (Matthew 28:19–20). He also said, “This gospel of the kingdom will be preached in all the world as a witness to all the nations, and then the end will come” (Matthew 24:14). That verse alone shows the gospel of the kingdom does not stop, does not change, and is not limited to Israel or to a future tribulation period.
The idea that the twelve preached a temporary gospel creates a problem, because Jesus said His words will judge mankind at the last day (John 12:48). If their message was only for one time period, then why would Jesus’ words judge everyone? The kingdom gospel is not just about a future millennium. It is about God’s rule beginning now in the hearts of those who obey Him and being completed when Christ returns. Jesus said, “The kingdom of God is within you” (Luke 17:21), and He also spoke of the kingdom coming in fullness at the end. It is one kingdom, one message, unfolding in stages, not different gospels for different dispensations.
The prophets spoke the same way. Daniel saw one everlasting kingdom that would crush all others and stand forever (Daniel 2:44). Isaiah spoke of a kingdom of righteousness and obedience to God’s law (Isaiah 2:2–3). Jesus did not replace this message. He fulfilled it and brought it to the world.
There is no “wrong gospel” when the words come from Christ Himself. What is wrong is teaching that Jesus’ gospel had an expiration date. The gospel of the kingdom preached by Jesus and His disciples is the same gospel that saves today, and it will be the same gospel preached until He returns.
Doug, Jesus said the kingdom was “at hand” because God’s rule had arrived with Him. The King of Kings was standing in front of them! Through Jesus, God was calling people to repent, to obey, and to enter His reign now, not just wait for a future age. The kingdom was near because hearts could submit to God immediately, sins could be forgiven, and lives could be changed. The kingdom begins within those who hear His words and keep them, and it will be completed in full when He returns in glory.
