A difference in teaching about the gospel has occurred among various Christian churches, each holding its own understanding of what the true gospel is. Some refer to it as the gospel of grace, others as the gospel of salvation or the gospel of Christ, while some call it the gospel of God or the gospel of the Kingdom. The only true gospel is the one presented in the Bible, and it is vital to search it out. It matters greatly what gospel Christians believe, as a double curse is pronounced on anyone who preaches a gospel different from the one taught by the apostles, who were directly instructed by Christ to proclaim this message. Jesus Himself preached the gospel of the Kingdom of God, proclaiming the good news that God's Kingdom would come and restore all things. This gospel not only announces the coming of a literal Kingdom that will reign over the whole earth when He returns, but also explains how we can be a part of it. The conditions for entering God's Kingdom are to repent and believe in the gospel. Repentance involves a complete turning of the mind and way of life to follow God, while believing the gospel includes both trusting in Christ and accepting the message He brought. Jesus spoke only what His Father in heaven told Him to speak, making the gospel of God, the gospel of Jesus, and the gospel of the Kingdom one and the same, originating from God and proclaimed by His Son. The gospel of grace is also part of the gospel of the Kingdom, as God's offer of grace and salvation is intertwined with the message of the Kingdom. The gospel of the Kingdom remains relevant today, preached not only by proclaiming that Jesus Christ will return soon to establish His government on earth, but also by teaching both believers and unbelievers how to live God's way of life.

I marvel that some are turning away so soon from Him who called them in the grace of Christ, to a different gospel. It took only a short time before someone perverted the gospel into something no longer recognized as good news. The gospel preached by Paul is not according to man, for he neither received it from man, nor was he taught it, but it came through the revelation of Jesus Christ. The glad tidings proclaimed by Jesus, Paul, and the other apostles throughout the world are revealed from God and can be learned only through supernatural disclosure. The true gospel message is not readily available to all, and one cannot simply find it by chance, as God must open the mind to receive it. Jesus designed even His parables to hide meaning rather than reveal it. In the early days, the apostles battled false gospels like legalism, which held that salvation came through works of the law rather than by grace, and Gnosticism, which centered on the idea that knowledge is the means to salvation and that spirit is good while flesh is evil. Another deceptive gospel focuses on the Messenger rather than the Message He brought. When Jesus preached the gospel, He revealed the way to the Kingdom of God, not trumpeting His own virtues. In commissioning His disciples, He instructed them to preach that the kingdom of heaven is at hand, to heal the sick, cleanse the lepers, raise the dead, and cast out demons. Nowhere did He tell them to preach about Jesus; His concern was always in proclaiming God's Kingdom. Before His ascension, He emphasized that repentance and remission of sins should be preached in His name to all nations. He was so focused on preaching the gospel of the Kingdom and ensuring His disciples understood it that it filled His conversations during His post-resurrection appearances to them. What gospel is learned is vitally important, and it must be the true gospel Christ brought, the revelation of the imminent Kingdom of God. Paul warned that if anyone, even an angel from heaven, preaches any other gospel than what was preached, let him be accursed.

The gospel, as presented by God, is not a matter of argument or debate but a clear pronouncement. He states it plainly, offering the hearer the choice to accept or reject it. Jesus instructed His disciples to preach the gospel in villages and cities, staying only where it was welcomed and leaving without contention where it was not. There was no pleading or coercion, simply an announcement of the message, allowing the hearer to decide. This approach remains unchanged; the gospel is non-negotiable, a complete package that must be accepted in its entirety or not at all. There is no compromise, no alternative path to the Kingdom of God, for there is only one gospel, one faith, and one hope. The gospel that Jesus preached is the gospel of the Kingdom of God, named so because it focuses on the ultimate goal. Yet, it encompasses far more than just the announcement of a future kingdom. Jesus was sent to preach this gospel, but also to heal the brokenhearted, deliver the captives, set people free, remove blindness, and open salvation. He came to save the world, to witness and testify to the truth, to produce belief, and to give eternal life, opening the way for resurrection. Thus, the gospel of the Kingdom of God includes all preparatory teachings and background necessary to reach that goal, covering aspects like the Beatitudes, law and grace, loyalty and devotion to God, and the foundation of understanding. It comprises the complete revelation of God to man, everything needed to call, teach, correct, and motivate a person toward salvation and entry into the Kingdom. The gospel is the power of God for salvation to those who believe, a dynamic force that is not merely words but a powerful means to teach, motivate, and create salvation. This power, akin to explosiveness, works both constructively and destructively, tearing down sin and building up righteousness and holiness. It is active, always working to produce God's image in us, piercing into the deepest parts to root out evil and make room for what is good. The gospel is living and powerful, sharper than a two-edged sword, discerning thoughts and intents, cutting in and out to transform the hearer. It bridges the gap between death and life, revealing God's way of life, which is foreign to carnal minds but packaged in a way that allows growth through a lifelong educational process. The essence of the gospel message, as preached by Jesus and echoed by Paul, includes repentance and faith—cutting away evil and building up what is necessary to become godly. This dual action of tearing down and building up is central to the gospel's power to produce sons in God's image. Paul felt compelled to preach this gospel, undeterred by trials, focused solely on fulfilling his ministry. He committed the entire revelation of God to those he taught, ensuring they received the whole counsel necessary for their eternal salvation. He warned against perversions of the gospel and false ministers who would draw followers after themselves, contrasting sharply with his own motivation to please God and preach the truth. Ultimately, Paul entrusted those he taught to God and His Word, the dynamic force of the gospel that works to produce salvation and eternal life, leading to an everlasting inheritance as God's children in His Kingdom.
