Here is a short Bible study on the contents of the gospel of the kingdom as John the Baptist and the Lord Jesus Himself presented in Matthew, Mark, and Luke. I have decided to not comment until the end, and just leave God’s word to speak for itself.
According to Matthew
In those days came John the Baptist, preaching in the wilderness of Judæa, And saying, Repent ye: for the kingdom of heaven is at hand. For this is He that was spoken of by the prophet Esaias, saying, The voice of one crying in the wilderness, Prepare ye the way of the Lord, make His paths straight. (Matthew 3:1–3)
From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand. (Matthew 4:17)
And Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people. And His fame went throughout all Syria: and they brought unto Him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and He healed them. (Matthew 4:23–24)
And Jesus went about all the cities and villages, teaching in their synagogues, and preaching the gospel of the kingdom, and healing every sickness and every disease among the people. (Matthew 9:35)
These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not: But go rather to the lost sheep of the house of Israel. And as ye go, preach, saying, The kingdom of heaven is at hand. Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give. Provide neither gold, nor silver, nor brass in your purses, Nor scrip for your journey, neither two coats, neither shoes, nor yet staves: for the workman is worthy of his meat. (Matthew 10:5–10)
Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for My Name’s sake. And then shall many be offended, and shall betray one another, and shall hate one another. And many false prophets shall rise, and shall deceive many. And because iniquity shall abound, the love of many shall wax cold. But he that shall endure unto the end, the same shall be saved. 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. (Matthew 24:9–14)
According to Mark
John did baptize in the wilderness, and preach the baptism of repentance for the remission of sins. (Mark 1:4)
Now after that John was put in prison, Jesus came into Galilee, preaching the gospel of the kingdom of God, And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel. (Mark 1:14–15)
According to Luke
And it came to pass afterward, that He went throughout every city and village, preaching and shewing the glad tidings of the kingdom of God: and the twelve were with Him, And certain women, which had been healed of evil spirits and infirmities, Mary called Magdalene, out of whom went seven devils, And Joanna the wife of Chuza Herod’s steward, and Susanna, and many others, which ministered unto Him of their substance. (Luke 8:1–3)
Then He called His twelve disciples together, and gave them power and authority over all devils, and to cure diseases. And He sent them to preach the kingdom of God, and to heal the sick. And He said unto them, Take nothing for your journey, neither staves, nor scrip, neither bread, neither money; neither have two coats apiece.
And whatsoever house ye enter into, there abide, and thence depart. And whosoever will not receive you, when ye go out of that city, shake off the very dust from your feet for a testimony against them.
And they departed, and went through the towns, preaching the gospel, and healing every where. (Luke 9:1–6)
This is mostly for the benefit of those who insist that the gospel of the kingdom is the message that we are to preach today and that there is no difference between it and the gospel of Jesus Christ that is all about His death, burial, and resurrection. It actually amazes me that to say that there is a difference is considered a “heresy”.
If anyone claims that they are still preaching the gospel of the kingdom, they absolutely should expect to be able to heal the sick, cleanse the lepers, raise the dead and cast out devils. If they are not able, then they are not preaching the gospel of the kingdom. If they claim that they are able, they should certainly do it for free, with no donation or faith promise required. They should also be going on their missionary efforts without a penny in their pocket.
In this day of grace, we preach the gospel of the GRACE OF GOD, that although the kingdom was rejected, God in grace postponed His righteous judgment and sent the “chief of sinners” to declare the gospel that although we are all enemies of God, Jew and Gentile alike, Christ died for us while we were yet sinners, and salvation is by grace through faith in Him. The kingdom will yet be established, but not until Christ comes and in righteousness “doth judge and make war” (Revelation 19:11).
We are in no way seeking to establish the kingdom of God on earth. The Lord Jesus Christ Himself will establish it. We are to preach to a lost and dying world the word of reconciliation, the word of the cross. To declare the kingdom and seek to do great things for God is admirable, but do great things for God, it should be expected that we do as He says in His word to us.
