The message of the kingdom of God is of utmost importance to believers, yet the church can sometimes fail to preserve its passion and urgency. While the church is meant to be a vessel for spreading this message, it is not immune to shortcomings. At times, the way the kingdom message is communicated can become weakened or even distorted, diminishing its impact on those who hear it.

Jesus provides a powerful metaphor for the kingdom of God in Luke 13:20-21, comparing it to “leaven, which a woman took and hid in three pecks of flour until it was all leavened.” This analogy would have been well understood by His audience. The mention of “three pecks of flour” held deep significance, as it symbolized devotion to God, hospitality toward others, and fellowship with God. These three elements formed the foundation of a faithful life during that time.

In this passage, the woman represents the church, which serves as God’s instrument for drawing people into fellowship with Him. The imagery aligns with the biblical portrayal of the church as the bride of Christ, emphasizing a nurturing and caring role. However, the introduction of leaven into the flour conveys a more complex message. Leaven, or yeast, is a fermenting agent that spreads throughout the dough, changing its composition. While yeast is sometimes associated with growth and transformation, in biblical contexts, it often symbolizes corruption and impurity.

The function of leaven is to permeate and transform the entire lump of dough, which in many biblical passages is used as an illustration of sin. For instance, 1 Corinthians 5:6-8 describes leavened bread as representing the old sinful nature. The idea that the woman in Jesus’ parable covertly places yeast into the flour suggests a warning about how the kingdom message can become tainted. Similarly, in Old Testament times, leaven was strictly forbidden in grain offerings to God (Leviticus 2:11), reinforcing the idea that God’s people were to remain spiritually pure and untainted by corruption.

For the church to fulfill its divine purpose, it must remain pure and unblemished by outside influences. The integrity of the kingdom message depends on the holiness of those who proclaim it. If the church allows itself to be compromised, the message can become distorted, leading people away from the truth rather than toward it. Only those who truly believe in the gospel and live according to its principles should be entrusted with delivering its message. The church must be vigilant in maintaining its faithfulness to God’s calling, ensuring that its teachings remain uncorrupted.

One of the key threats to the church’s purity is the leaven of hypocrisy. Jesus warned His disciples to “beware of the leaven of the Pharisees, which is hypocrisy” (Luke 12:1). Hypocrisy occurs when a person’s outward appearance of righteousness does not align with their inward reality. It is a dangerous influence that can lead even strong believers astray, as seen in Galatians 2:13. Christians must actively reject hypocrisy, as it belongs to the former sinful self (1 Peter 2:1). The only way to avoid this danger is through a genuine pursuit of Christ. By continually seeking to know and follow Him, believers can ensure that their faith is authentic and not merely for show.

Another form of corruption that threatens the church is the leaven of rationalism. The Sadducees exemplified this mindset, as they prioritized political influence over spiritual truth and denied the supernatural aspects of faith. Rationalism, which elevates human reasoning above divine revelation, weakens the church’s dependence on God. Jesus emphasized the necessity of faith and prayer, stating that those who lack them have little faith (Matthew 16:8). To guard against rationalism, believers must rely on God’s wisdom, which grants them perseverance and joy even in the face of trials (James 1:2).

Additionally, the church must be wary of the leaven of materialism. An excessive focus on wealth and worldly success reveals a heart that is dissatisfied with God. From the early church onward, many congregations have struggled with financial hardship, yet their faith remained strong. The danger of materialism is that it can lead to lukewarm faith, where believers become complacent and spiritually stagnant. A church that prioritizes material wealth over spiritual devotion risks secularization and idolatry, losing sight of its true mission.

Jesus’ words in Luke 13:21 serve as a sobering warning: “until it was all leavened.” This phrase suggests that corruption will continue to spread unless the church repents. However, there is hope in repentance. When believers turn back to God and seek renewal, He restores them and purifies His church. Only those who are truly repentant can be used by God to advance His kingdom. Through humility, faith, and commitment to the truth, the church can resist the corrupting influences of hypocrisy, rationalism, and materialism, ensuring that the message of the kingdom remains pure and powerful.

The Kingdom of God was the central theme of Jesus’ ministry (Luke 4:43). It is not a fictional or mythical concept like Atlantis but a reality that Jesus came to reveal. The kingdom is where Jesus reigns, and as believers, we are already part of it. However, there are common misunderstandings about the Kingdom of God that must be clarified to fully grasp its significance.

Clarifying Misunderstandings Some believe the Kingdom of God is only spiritual, but Jesus made it clear that it is both spiritual and earthly (Luke 17:21, Romans 14:17). Others think the kingdom is solely an earthly rule, but Colossians 1:20 teaches that all things, in heaven and on earth, have been reconciled to Christ. Some equate the kingdom with the church, but while the church belongs to the kingdom, it is its vanguard, proclaiming the way to enter (Matthew 16:18-19).

The Kingdom: Already, But Not Yet The Kingdom of God is both a present reality and a future promise. When Jesus came, the kingdom was inaugurated (Matthew 2:11, Luke 17:21). The disciples expected its full establishment (Acts 1:6), but it will only be completed at Jesus’ second coming when He defeats all evil and reigns forever (Revelation 19:11-15). Just as believers are justified now but await glorification, the kingdom is promised but not yet fully realized.

The Power of the Kingdom Jesus illustrated the kingdom’s power by healing a woman bound by Satan (Luke 13:16). This was a demonstration of the kingdom’s victory over darkness. Today, many declare “Christ is King” in response to political turmoil, but we must understand His reign biblically (John 18:36-37). His kingdom is not of this world, yet it is stronger than any earthly power (Daniel 2:33). Jesus is the rock that crushes all human empires.

Five Truths About the Kingdom that encourage and strengthen us

1. Powerful in All Circumstances The kingdom may seem small, like a mustard seed, but it has world-changing power (Luke 13:18-19). Jesus, a humble man who was crucified, overturned the Roman Empire in just a few centuries. Likewise, small beginnings—like a few missionaries in India—can transform entire nations.
2. Supernaturally Sustained The kingdom’s growth is not by human effort but by Jesus, the divine farmer who personally tends to His people (Luke 13:8, Philippians 1:6). He nourishes, prunes, and strengthens His kingdom, ensuring that it flourishes in His perfect timing. If God is for us, no one can stand against us (Romans 8:31). We must ask ourselves: Do we truly know Him, and do we walk daily in His power, allowing Him to sustain and grow us?
3. Planted in Good Soil The kingdom is sown in God’s garden, intentionally placed in the best conditions for growth (Luke 8:5, Matthew 13:23). Unlike seeds scattered on rocky ground or among thorns, we are planted in the rich soil of God’s providence and care. No trial, hardship, or struggle occurs outside of His sovereign will. We are never abandoned, even in difficult seasons. His love is steadfast and unwavering, embracing us with an undivided heart.
4. Marked by Growth and Repentance just as a seed must grow to maturity, so must we as believers. Growth in the kingdom of God is not optional—it is essential. True repentance is the first step, leading to faith and transformation (Mark 1:15). It is not merely a momentary decision but an ongoing, lifelong turning toward Christ. Nicodemus, who initially came to Jesus in secret, was later emboldened to publicly honor Him (John 3:3, John 19:39). Are we likewise growing in our faith? Are we actively striving to enter the narrow gate (Luke 13:23-24), seeking His kingdom and righteousness above all else (Matthew 6:33)?
5. A Future of Blessing The kingdom is vibrant, a place of joy and peace. The birds resting in the mustard tree represent God’s blessing (Matthew 5:3,10). Revelation gives us a vision of a future kingdom without sorrow, only eternal joy (Revelation 21:2,4). This is our hope and our destiny.

The Kingdom of God is a present and future reality, full of power, promise, and transformation. Though it is not yet fully established, we experience its influence daily. It is powerful and transformational because Jesus is King. As we wait for its full realization, let us live as kingdom people—seeking, growing, and proclaiming Christ’s reign until He comes again. Come, Lord Jesus! (Revelation 22:20).
