What Jesus Talked About the Most

Many people assume the goal of Christianity is to go to heaven. However, throughout the New Testament, not a single sermon concludes with “if you follow these steps, you can go to heaven when you die.” Far more often we find sermons proclaiming Jesus’s status as the anointed King (Christ) and Ruler (Lord). For example, in Peter’s Pentecost sermon, he declared “God has made him both Lord and Christ, this Jesus whom you crucified” (Acts 2:36). Similarly, Peter preached to Cornelius’s household about “Jesus Christ,” who is “Lord of all” (Acts 10:36). Even in Roman custody, Paul tried to convince others about Jesus and the Kingdom of God (Acts 28:23). Jesus’s kingship and lordship are at the very heart of the gospel (Romans 1:1-4).

The New Testament mentions the “kingdom” over 150 times, more than twice the frequency of the word “church.” While it is certainly worthwhile to study what the New Testament teaches about the church and heaven, it is unfortunate that the kingdom does not receive greater emphasis in modern Christianity. This was not the case with Jesus, who talked more about the kingdom than any other subject.

Jesus Preached the Kingdom

The gospel authors consistently emphasize the Kingdom as the main emphasis of Jesus’s teaching. For example, Mark 1:15 summarizes Jesus’s preaching throughout Galilee in one sentence: “The time is fulfilled, and the kingdom of God is at hand; repent and believe in the gospel.” Matthew 4:23 describes him as teaching in synagogues and “proclaiming the gospel of the kingdom.” Similarly, Matthew 9:35 and Luke 8:1 also highlight the kingdom as subject of Jesus’s message while healing diseases and afflictions. These passages all underscore the kingdom as the central focus of Jesus’s teachings.

When Jesus taught his disciples to pray, he taught them to pray about the kingdom (Mt. 6:9-13). Jesus instructed them to preach about the kingdom (Lk. 9:2; 10:9). His miracles, such as healing the sick and casting out demons, demonstrated that the kingdom was breaking into the world (Lk. 11:20). Jesus continually taught about how to enter the kingdom (Mt. 5:3; 6:33; Mk. 10:15; Lk. 13:3; 14:15-24; Jn. 3:3-5). Most of Jesus’s parables were used to explain the nature of his kingdom (Mt. 13:24, 31, 33, 34, 44, 45, 47; 18:23; 20:1, 22:2; 25:1; Mk. 4:26, 30, Lk. 13:18, 20).

Why did Jesus spend so much time talking about the kingdom? Because Jesus understood this to be the reason he was sent.

He said to them, “I must preach the good news of the kingdom of God to other towns as well; for I was sent for this purpose.”
Luke 4:43

What Is the Kingdom?

To put it simply, the Kingdom of God is the place where God reigns supreme and His will is done (Mt. 6:9-10). It is the “dome” (or “dominion”) over which God reigns as King.

Everyone in the first century knew what a “kingdom” was, but today we tend to use words like “nations,” “countries,” or “states” to describe political dominions. While modern rulers don’t typically use the title “King,” democratically elected rulers continue to hold similar authority to govern their respective states. Despite differences in how today’s rulers ascend to power, the concept of kingdoms and dominions with authoritative rulers persists in today’s world.

God also has a “kingdom” where choices are made in harmony with His will. Jesus, who is sinless, loving, and obedient, is the perfect example of what it looks like for God to reign over a person’s life completely. To enter his kingdom, one must be born again of water and Spirit, surrendering their life to continual imitation of Christ (John 3:3, Rom. 6:1-14; Phil. 2:5-8).

In the Sermon on the Mount, Jesus taught his disciples to pray, “Your kingdom come, Your will be done” (Mt. 6:10). God’s kingdom is where God’s will is done.

When is the Kingdom?

The Kingdom of God was not preached as a distant future event but as something imminent. John the Baptist and Jesus each preached that the Kingdom was “at hand” (Mt. 3:1-2; Mk. 1:15).

Similarly, in Luke 11:20, Jesus said,

But if it is by the finger of God that I cast out demons, then the kingdom of God has come upon you.

Jesus even told his disciples that some of them would witness the coming of the kingdom in their lifetime.

Truly, I say to you, there are some standing here who will not taste death until they see the Son of Man coming in his kingdom.
Matthew 16:28

For this reason, it should be no surprise when Paul and John also speak as if Christians were already in God’s kingdom at the time of their writing (Col. 1:13; Rev. 1:9). While there is a sense in which we still wait for the ultimate appearing of his kingdom, when the kingdom is delivered to the Father, when death is no more and every tear is wiped away (1 Cor 15:24, 2 Tim. 4:1; Rev. 11:15; 21:3-4), the kingdom of God is not merely a future hope for eternal life. It is a real kingdom presently here on earth.

If God’s kingdom is here, where is it?

Where is the Kingdom?

When questioned by the Pharisees about the arrival of God’s kingdom, he answered them:

The kingdom of God is not coming in ways that can be observed, nor will they say, “Look, here it is!” or “There!” for behold, the kingdom of God is in the midst of you.
Luke 17:20-21

Unlike earthly kingdoms with defined borders, Jesus’s kingdom exists anywhere things are done God’s way. Most of the world, filled with filled with war, violence, coercion, poverty, child abuse, sex trafficking, theft, injustice, hatred, and more, stands in opposition to God’s kingdom. But there are places where God’s will is done on earth as it is in heaven.

Jesus clarified to Pilate that while his kingdom is not of earthly origin, and is not sustained by earthly means, it is nonetheless a real kingdom, where Jesus reigns as a real King.

Jesus answered, “My kingdom is not of this world. If my kingdom were of this world, my servants would have been fighting, that I may not be delivered over to the Jews. But my kingdom is not of this world.”

Then Pilate said to him, “So you are a king?” Jesus answered, “You say that I am a king. For this purpose I was born and for this purpose I have come into the world – to bear witness to the truth – everyone who is of the truth listens to my voice.”
John 18:36-37

Jesus’s kingdom is as real as any other kingdom, and it is on earth now. If you want to know where God’s kingdom is, look to the places where people have reborn by both water and Spirit, and are heeding Jesus’s voice.

Who is the Kingdom?

Before identifying who is in the Kingdom of Christ today, it is helpful to differentiate this kingdom from the kingdom of God as it is otherwise described in the Bible. All that God did prior to the establishment of the Kingdom of Christ was done with that purpose in mind.

In the sense of rightful authority, all creation belongs to the Creator. But in the garden of Eden, something pivotal happened. Adam and Eve, rather than obeying the voice of their Creator, obeyed the voice of the Serpent. In so doing, they ceded authority to him who would eventually lead the whole world astray. In this sense, Satan too has a kingdom. But his kingdom only exists because he has usurped authority which did not at any point rightfully belong to him.

Since that time, two kingdoms have existed side by side, God’s and Satan’s, each bidding for mankind’s allegiance. After rescuing Abraham’s family from slavery in Egypt, God ruled over His kingdom of Israel through the law of Moses. Even as God anticipated a king (Deut. 17:14-20), He warned against the attitudes and actions which would defy his ultimate authority. Unfortunately, Israel rejected God’s reign, choosing instead to imitate surrounding earthly kingdoms (1 Sam. 8), leading to Israel’s decay and punishment (Hosea 13:11).

It was during this period of decay when the prophets announced that God would establish a new eternal Kingdom, where God would reign through His anointed King (Is. 9:6-7). Daniel too spoke of a Kingdom that was coming that would cut in pieces and destroy other earthly kingdoms (Dan. 2:36-45; 7:13-14).

Jesus was and is the fulfillment of this hope for a Kingdom. Paul refers to those who “boast in the cross of the Lord Jesus Christ” as the new “Israel of God” (Gal. 6:14-16), and Peter refers to Christ’s church as “a holy nation” (1 Pet. 2:9). That’s because Jesus has made them to be, “A kingdom of priests for God” (Rev. 5:10).

What Kingdom Are You a Citizen Of?

Salvation is much more than simply going to heaven. It includes rescue from the political forces and evil structures of this world which have aligned themselves with Satan (Col. 1:13; 2:15; 1 Jn. 3:8). The fact that Jesus established a Kingdom means that people are now forced to choose which Kingdom they pledge their allegiance to. We may be “born” into an earthly nation, but we are “born again” into God’s Kingdom.

It is important to note that the Bible rejects the concept of a “dual citizenship,” emphasizing that Christians live as foreigners, strangers, or exiles in their earthly nations. Our citizenship is not on earth, but in heaven (Phil. 3:20). The faithful are those who acknowledge themselves as strangers and exiles on the earth (Heb. 11:13). Christians are exiles, and as such, they are to abstain from the passions of the flesh which characterize the world (1 Pet. 1:17; 2:11).

The Kingdom of God is here now. This truth lies at the very core of the gospel which Jesus proclaimed, and it should be central to our message as well.
