The conditions for entering God's Kingdom are simple in concept: "repent and believe in the gospel." Repentance is a complete turning or changing of the mind and way of life to follow God. And God's way of life is defined by His commandments (Matthew 19:17). We repent by quitting our former sinful way of life and keeping God's commands.
Believing the gospel encompasses both believing in Christ as well as believing what He said (John 8:30-31). Millions believe that He came as their Savior and now lives eternally as their soon-coming King, while paradoxically rejecting the very message He brought to save them!

The True Gospel
Is there any doubt in our minds that we are within striking range of the return of Jesus Christ? The gospel of Jesus Christ has been preached for almost two thousand years, and prophecies made by Him and others regarding His return are being fulfilled. The crisis at the close is almost upon us. Mankind's only hope is revealed in the gospel, yet we find great ignorance regarding what His good news is.
The complete secularization of the Western, "Christian" world is almost accomplished, and doctrinal confusion abounds. It seems as though the vast number of professing Christians believe that all one must do is believe in the name of Jesus Christ to be saved. This is most certainly required, but Jesus Himself says in Mark 1:15 that one must believe in the gospel in order to be saved.
That is quite a bit different than merely believing in Jesus. While it is definitely true that Jesus died for our sins, the true gospel provides a great deal more instruction regarding Christianity and its purpose than solely Jesus' part in our salvation. It reveals that a Christian must play an active part in the spiritual creation that God is working in and through men.
One of the more effective deceptions Satan has palmed off on mankind is that all God is attempting to do is to "save" people. Most Christians somehow fail to think of God and His Son, Jesus Christ, as actively involved in doing something more with those who are converted.
Consider this process, which most people believe: At some time in his life, the "saved" one had perceived the need to be forgiven of his sins. He then asked God to forgive him, and from that point on, because of Christ's blood, he was "saved." Is this true? Though this illustration has been simplified a great deal, it is nevertheless close to the prevalent belief.
We will add a biblical fact to that scenario. Almost all Bible commentators hold that the Israelite's experience of walking through the wilderness following Israel's release from bondage to Egypt is a type of a Christian's walk following his conversion. Walking is typical of laboring or working to reach an objective.
Did the Israelites arrive in the Promised Land - a type of the Kingdom of God - immediately upon release from their bondage? No! They had ahead of them a forty-year journey filled with trials. As they journeyed, God worked with them and supplied their needs, preparing them for their inheritance. Release from Egypt only began another aspect of God's work with them. To reach their objective, a great deal of labor lay ahead of them.
We all need to come to grips with the reality that our Creator is a God who works. He is not merely observing mankind, or worse still, having gone way off somewhere in the vastness of the universe, letting things run more or less on their own. Jesus says in John 5:17, "My Father has been working until now, and I have been working." More plainly, the Father began working in the indefinite past and has continued working right up till now. God is not sitting around passively saving people.
In Psalm 74:12, notice the psalmist Asaph's revelation of what God is doing: "For God is my King from of old, working salvation in the midst of the earth." The salvation of human beings requires God to work, yet some seem to think that all He does is as simple as turning a "forgiveness switch," and the person is saved. However, in various places both the Father and the Son are called "Saviors." It ought to be apparent that saving a person from circumstances he needs deliverance from requires a savior to work. If a deliverer or savior does not make a strenuous effort, the one in need of rescue will not be saved.
Jesus testified that the Father was working at that very moment. The Bible provides abundant records of Jesus, our Savior, working on behalf of mankind: teaching, counseling, praying, healing, setting the example for His disciples, and obeying His Father flawlessly in order to be the sacrifice for the forgiveness of our sins. Further, He says in John 14:10, "Do you not believe that I am in the Father, and the Father in Me? The words that I speak to you I do not speak on My own authority; but the Father who dwells in Me does the works." Jesus thus shows the Father to be His partner in His ministry.
In addition, when Jesus rose from the grave and ascended to heaven, He was made Head of the Church, as well as its High Priest. As such, He is responsible to the Father for working with the members of His Body, interceding on our behalf. He thus bears great responsibility for the salvation of its individual members and the success of the church as a whole. These vital tasks require His careful attention, especially as events near the crisis at the close of the age.
The conclusion is obvious: The work of God abounds with works for all concerned in seeking the objective He has set before us in His purpose. That objective is the Kingdom of God.

Is the Christian Required To Do Works? (Part Five)
Christ links repentance with the Kingdom of God and believing the gospel. Once one hears the true gospel and believes it, he begins to change the way he thinks. Peter ties repentance with forgiveness of past sins and God's giving of His Spirit. Once the Ethiopian eunuch heard Philip's explanation of the Bible, he changed his thinking (repented) and was baptized. Initial repentance includes recognition, acceptance, and belief of the true gospel and making changes in one's life to conform to the new way.

"This Gospel of the Kingdom Shall Be Preached"
What is the gospel—the "good news"? "Just believe on the name of Jesus and you will be saved" is a common message of many preachers. Others proclaim that the gospel is that Jesus came to die for our sins. Still others preach a rather insipid and saccharine "Jesus loves you" message. All of those catchy phrases have relevance to Jesus' message—we certainly must believe in Jesus, He did die for our sins, and He surely loves us—but nowhere does Jesus directly state that the gospel is about Him!
Instead, the good news is about a momentous purpose that God is accomplishing. Jesus spoke the words that the Father gave Him to preach, most emphatically confirmed in John 12:49-50:
For I have not spoken on My own authority; but the Father who sent Me gave Me a command, what I should say and what I should speak. And I know that His command is everlasting life. Therefore whatever I speak, just as the Father has told Me, so I speak.
What is Jesus' own testimony about the subject of His preaching? Notice these verses:
» Matthew 4:23: "And Jesus went about all Galilee, teaching in their synagogues, preaching the gospel of the kingdom, and healing all kinds of sickness and all kinds of disease among the people."
» Matthew 24:14: "And 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."
» Luke 4:43: "[Jesus] said to them, 'I must preach the kingdom of God to the other cities also, because for this purpose I have been sent.'"
» Luke 16:16: "The law and the prophets were until John. Since that time, the Kingdom of God has been preached, and everyone is pressing into it."
Jesus' announcement of the good news is that the Father will establish His Kingdom and His capital city on earth. He Himself will be here, no longer separated from His children—no longer unseen and ruling indirectly through agents from His present location in heaven but ruling directly on earth. It is to this awesome, mind-boggling future that we, as a part of His Family, are being summoned to prepare for and to participate directly in.
Jesus is certainly mankind's Savior, having died for our sins, but to be properly understood, that event must be seen within the context of preparation for and the establishment of the Kingdom of God on earth. A kingdom has four basic elements: a king, a territory it occupies, subjects within that territory, laws, and a form of government through which the will of the ruler is exercised. Each of these elements is part of the gospel.
Has the founder of any other religion offered a message and program that can even begin to match what Jesus taught? This is truly the most wonderful message mankind could possibly receive, and it came only through Jesus.

Where Is God's True Church Today?
From these three verses (Acts 2:38; Mark 1:15; Acts 8:12), we understand the two prerequisites for baptism: repentance and belief of the gospel of the Kingdom of God. The people of Acts 2 showed by their reaction that they believed what Peter had preached (verse 37), and thus they needed only to repent of their sins and their human nature before they were baptized (verse 41). One need not be a Bible scholar or be living perfectly to be baptized; these things are part of growing in the grace and knowledge of Jesus Christ after baptism (II Peter 3:18).
