A Challenge for the Modern Christianity

 The Gospel Jesus Proclaimed: Rediscovering the Message of the Kingdom of God

When we return to the beginnings of the Christian faith, an important question naturally arises: What exactly was the gospel that Jesus proclaimed? 

A careful reading of the Gospel narratives reveals that the central theme of Jesus’ preaching was the Kingdom of God. The opening proclamation of his ministry clearly expresses this message: “The kingdom of God has come near; repent and believe the good news” (Mark 1:15). Likewise, in Luke 4:43 Jesus states explicitly, “I must proclaim the good news of the kingdom of God to the other towns also, because that is why I was sent.”

These statements reveal the heart of Jesus’ mission. He did not come primarily to establish a new religious system. Rather, he came to call human beings back under the reign of God. According to Jesus, God is the true king of the world, yet human beings live as though they are independent of God’s rule. Much of Jesus’ teaching describes this condition of alienation from God.

One of the most powerful illustrations of this reality appears in the parable of the Prodigal Son (Luke 15). In the story, the younger son leaves his father’s house and ends up living in misery, even among pigs. This image powerfully symbolizes humanity’s spiritual condition: people who have wandered away from the life of God. Yet the turning point of the story occurs when the son “comes to himself,” regains his sense, and decides to return to his father. When he returns, the father receives him with compassion and restores him.

The message of this parable highlights the essence of repentance. Entry into the Kingdom of God does not occur merely through adopting a religious identity or accepting certain doctrines. Rather, it happens when human beings recognize their lost condition, turn back to God, and accept God’s reign in their lives.

Jesus explained the nature of the Kingdom of God through many parables. One of the most striking is the parable of the yeast in Matthew 13:33. Just as a small amount of yeast eventually leavens the entire dough, the Kingdom of God begins in seemingly small ways but gradually transforms the whole. Similarly, the parable of the mustard seed (Matthew 13:31–32) illustrates how something that begins very small can grow into something large and influential. These images portray the Kingdom of God as a transforming power that spreads quietly but profoundly within human life and society.

Jesus also emphasized that the Kingdom of God is not merely an external political reality. In Luke 17:20–21 he states that the Kingdom of God does not come with visible signs, but that “the kingdom of God is among you.” In other words, the Kingdom of God is fundamentally the reality of God’s reign being accepted in human lives.

However, after Jesus’ death and resurrection, some scholars have observed a shift in the emphasis of Christian proclamation. The German theologian Albert Schweitzer famously summarized this observation with the statement: “Jesus proclaimed the Kingdom of God; the church proclaimed Jesus.” This remark does not deny the importance of Jesus but highlights a historical development: while Jesus’ own preaching focused on the coming reign of God, the early church increasingly centered its proclamation on the person of Jesus himself.

Historically, this development is understandable. The life, death, and resurrection of Jesus profoundly shaped the faith of his followers. As a result, the apostles proclaimed Jesus as Lord and Messiah. For example, in Acts 2 Peter’s sermon focuses on the death, resurrection, and exaltation of Jesus. The central claim of that sermon is that God has made Jesus both Lord and Christ.

Yet this raises an important theological question. Do beliefs about Jesus, by themselves, bring people into the Kingdom of God? The teaching of Jesus suggests that something deeper is required. Throughout the Gospels, the fundamental condition for entering the Kingdom is repentance and transformation of life. Jesus repeatedly calls people to repent, warning that without repentance people cannot share in God’s kingdom (Luke 13:3).

Beliefs about Jesus may inspire people to listen to him and take his message seriously. They may draw attention to his authority and significance. But belief alone does not automatically bring a person into the reality of God’s reign. The Kingdom of God becomes real in a person’s life when that person turns toward God and willingly lives under God’s rule.

This insight presents an important challenge for the contemporary church. In many contexts Christian preaching has focused primarily on doctrines about Jesus—his identity, his divinity, and the meaning of his death. While these beliefs are central to Christian theology, there is a risk that the message Jesus himself proclaimed—the good news of the Kingdom of God—can fade into the background.

The world today is marked by deep spiritual confusion and longing. People search for meaning, reconciliation, and hope. In such a context, the message that Jesus proclaimed remains profoundly relevant: human beings are invited to turn back to God and live under God’s life-giving reign.

Therefore the church in every generation must continually ask itself an important question: What is the primary message we are proclaiming to the world? Is it merely a set of beliefs about Jesus, or is it the transforming call to enter the Kingdom of God that Jesus himself announced?

The future vitality of Christian faith may well depend on rediscovering this original emphasis. When the good news of the Kingdom of God is proclaimed again with clarity and conviction, people are invited not merely to accept doctrines but to experience a profound change of life. They are called to repentance, restoration, and participation in the life of God.

In this sense, rediscovering the gospel of the Kingdom is not a rejection of Jesus but a return to the heart of his message. It is the good news that God’s reign is near, that reconciliation with God is possible, and that anyone who turns back to the Father can enter the joy and freedom of life in God’s Kingdom.

The Kingdom of God and the Kingdom of Satan

A Summary of the talk given at st. Mary's church, Houston on Jan 8, 2012. Listen to the talk here.

John, the Baptist, invites people to receive a baptism from him in River Jordan. Jesus receives baptism from him.  After the baptism, Jesus sees a vision—God says to him, “You are my beloved son”. He also sees the Holy Spirit descending on him. Then Jesus goes to the desert, where he fasts for forty days.  He confronts Satan there. He overcomes Satan. Then he travels around his land proclaiming the news, “The Kingdom of God is at hand.”

These are the events recorded in the gospels. But if we ask why these events happened, we don’t see the answers there. There are underlying reasons. The readers in the first century knew these reasons so well that the writers had no need to write them. If we ask why John baptized people, and why he did it in river Jordan, what was the meaning of Jesus’ vision, why he went to the desert for forty days, why Satan tried to eliminate him, why Jesus spread the news of the kingdom, we have no answers in the gospels. If the writers knew that their books would be read all over the world even after two millennia, they would have written more elaborately adding the underlying reasons.

Here I am making an attempt to find out the underlying reasons. Life was miserable for the people in Jesus’ land. They were under the Roman rule, who taxed them heavily, and they also had to pay taxes to the temple. A lot of people were sick—physically and mentally. Demon possession was mental disease. They explained this miserable situation by relating it to their own past. They knew that they were slaves in Egypt a millennia ago. Now they assumed that they are in slavery again—slaves to a new Pharaoh, Satan.

They assumed that the world has two levels—heaven, the upper level, and earth, the lower level. God is the ultimate ruler of the whole world. Satan was originally Lucifer, and he was appointed by God to rule the earth on behalf of him, but eventually he rebelled against God. The original meaning of Satan is “the rebel” or “the adversary”. Thus the earth, which was originally a part of the kingdom of God was now the kingdom of Satan.

All the problems on earth are due to the fact that the earth is ruled by Satan. God will soon overthrow Satan and appoint someone else. The one who will be appointed was called the Messiah, which means the anointed.

This is the underlying story. Now using this story let us explain the events one by one.

John the Baptist asked people to escape from the slavery of Satan and enter the land of Canaan, the Kingdom of God, anew by crossing the River Jordan. When people walked to John in river Jordan, they were rejecting the rule of Satan and joining the Kingdom of God.

After Jesus took baptism, he was also anointed by the Holy Spirit as the messiah. He got the affirmation from God that he was the messiah, the one appointed to overthrow the rule of Satan.

He went straight to the desert. He was there for forty days like the old Israel, which was there for forty years. Satan tried to eliminate him in three different ways:

1.       Satan tried to shake his conviction and his will. He said to Jesus, “If you are the son of God, turn these stones to bread”.  Satan hoped that this will discourage Jesus, and make him withdraw.

2.       Satan tried to eliminate him physically. He asked Jesus to jump from the top of the temple.

3.       Satan tried to bring him under his power. He offered the rule of all the kingdoms in the world, if only he would submit to the will of Satan.  

Now Jesus came to the midst of his people and began to proclaim the good news, “The Kingdom of God is at hand”. Wherever he went, he asked people to get out of the slavery of Satan. He also saved people from the slavery by healing sickness and casting out demons.
