THE CONSUMING FIRE: DIVINE DESIRE OR STRANGE FIRE By: Major Frank Materu
Key Scripture:
“For our God is a consuming fire.” — Hebrews 12:29
________________________________________
Introduction
Throughout Scripture, fire is often used as a symbol of God’s presence, power, holiness, and purification. Fire can illuminate, refine, and energize, but it can also destroy and consume. The question that every believer must eventually face is this: What kind of fire is burning within? Is it the holy fire of divine desire for God’s Kingdom, or is it the strange fire of carnal lusts and worldly ambitions?
Every human being is driven by some form of inner fire. This fire manifests in desires, ambitions, passions, and pursuits. For some, the fire is a desire for wealth and possessions. For others, it is a desire for recognition, influence, or pleasure. Still others are consumed by intellectual pride, addiction, or the endless pursuit of worldly success. These fires can appear harmless or even admirable from a human perspective, yet they may be entirely disconnected from the purposes of God.
God calls His people to burn with a different kind of fire—a holy fire that originates from His Spirit. This divine fire produces love, righteousness, truth, and devotion to God’s Kingdom. It is a fire that purifies rather than corrupts and energizes rather than enslaves. Those who walk in this fire are motivated not by selfish ambition but by a deep desire to know God and fulfill His purposes.
However, Scripture warns repeatedly against offering “strange fire” before the Lord. Strange fire represents any passion or desire that originates from the flesh rather than from the Spirit. It includes not only obvious sins but also subtle forms of self-centered ambition and worldly attachment. When believers allow strange fire to burn within them, they risk drifting away from the path that God has prepared.
This lesson explores the nature of the consuming fire, the danger of strange fire, the battle against carnal desires, and the call to burn with divine passion for the Kingdom of God.

The Nature of the Consuming Fire
“For the Lord thy God is a consuming fire, even a jealous God.” — Deuteronomy 4:24
________________________________________
God is described as a consuming fire because of His holiness and purity. His presence burns away impurity and exposes everything that is false or corrupt. This fire is not destructive to those who walk in obedience; rather, it refines and strengthens them.
The consuming fire of God is meant to ignite the hearts of believers with a passion for righteousness. It produces a desire to know God more deeply and to live according to His will. This fire brings clarity and purpose, guiding believers along the path of truth.
When the fire of God burns within a person, it becomes the central motivation of their life. Their thoughts, decisions, and actions are shaped by their desire to honor God. They begin to see the world differently, valuing eternal things above temporary pleasures.
This divine fire is not forced or artificial. It is the natural result of a living relationship with God. As believers draw closer to Him, His fire begins to burn more brightly within them.

The Danger of Strange Fire
“And there went out fire from the Lord, and devoured them, and they died before the Lord.” — Leviticus 10:2
________________________________________
The concept of strange fire originates from the account of those who offered unauthorized fire before the Lord. This act represented a failure to honor God’s holiness and a willingness to substitute human initiative for divine instruction.
Strange fire represents any passion or pursuit that originates from the flesh rather than from the Spirit. It includes desires that may appear acceptable or even admirable but are ultimately rooted in self-centeredness rather than devotion to God.
Many people burn with the fire of ambition, seeking recognition and status. Others burn with the desire for wealth and possessions. Still others are consumed by the pursuit of pleasure or intellectual achievement. While these pursuits may not always be sinful in themselves, they become dangerous when they replace devotion to God.
When strange fire burns within a person, it gradually draws them away from the path of righteousness. It creates a divided heart, making it difficult to fully follow God’s will.

The Many Forms of Carnal Fire
“For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father.” — 1 John 2:16
________________________________________
Carnal fire takes many forms, and it often disguises itself as something good or desirable. It may appear as the pursuit of success, comfort, or security. It may manifest as a desire for recognition or approval. It may even appear as religious activity motivated by pride rather than love.
One of the most powerful forms of carnal fire is the desire for possessions. Many people are driven by an endless pursuit of more—more money, more property, more status. This pursuit can become all-consuming, leaving little room for spiritual growth.
Another form of carnal fire is the desire for pleasure. This includes not only obvious indulgences but also subtler forms of self-gratification. When pleasure becomes the primary goal of life, it displaces the desire for God.
Carnal fire is insatiable. It always demands more, yet it never truly satisfies. Those who are driven by it often find themselves trapped in cycles of desire and disappointment.

The Battle Against the Old Nature
“For the flesh lusteth against the Spirit, and the Spirit against the flesh.” — Galatians 5:17

________________________________________
The Christian life is a continual battle between the flesh and the Spirit. Even after conversion, the old nature continues to resist the new life in Christ. This resistance often manifests as temptation and inner conflict.
The old nature seeks to rekindle the fires of past desires. It attempts to draw believers back into patterns of thinking and behavior that belong to their former lives. This struggle is a normal part of spiritual growth, but it requires vigilance and determination.
Believers must remain alert and actively resist the influences of the flesh. They must continually renew their minds and align their desires with God’s will.
Victory in this battle comes through dependence on the Holy Spirit. As believers yield to His guidance, they gain strength to overcome the desires of the flesh.

The Fire of Divine Desire
“Did not our heart burn within us, while he talked with us by the way?” — Luke 24:32
________________________________________
The fire of divine desire is a passion for God and His Kingdom. It is a longing to know Him more deeply and to fulfill His purposes. This fire produces joy, peace, and a sense of purpose.
Those who burn with divine desire are willing to let go of anything that hinders their spiritual growth. They recognize that earthly possessions and ambitions are temporary, while the things of God are eternal.
Divine desire transforms priorities. It shifts the focus from self-centered pursuits to God-centered living. It inspires acts of love and service, reflecting the character of Christ.
This fire is sustained through prayer, worship, and obedience. As believers draw closer to God, their desire for Him grows stronger.

Freedom from the Burden of Possessions
“Lay not up for yourselves treasures upon earth.” — Matthew 6:19
________________________________________
One of the greatest obstacles to divine desire is attachment to material possessions. When people become overly focused on acquiring and maintaining possessions, their spiritual lives often suffer.
Possessions require time, energy, and attention. They can become burdens that distract from the pursuit of God. In extreme cases, they can become idols that replace devotion to Him.
True freedom comes from holding possessions loosely. It comes from recognizing that material things are tools rather than treasures.
Those who are free from the burden of possessions are better able to follow God’s leading. They are able to respond quickly and fully to His call.

The Call to Spiritual Warfare
“Fight the good fight of faith.” — 1 Timothy 6:12
________________________________________
The Christian life involves spiritual warfare. Believers must contend not only with their own flesh but also with the influences of the world and the forces of darkness.
This warfare requires vigilance and discipline. It requires a commitment to truth and a willingness to resist deception.
Those who engage in this battle with faith and perseverance will experience victory. They will see the power of God at work in their lives and in the world around them.
Spiritual warfare is not fought with human strength but with spiritual weapons. Prayer, faith, and the Word of God are essential in this battle.

Burning for the Kingdom
“Seek ye first the kingdom of God, and his righteousness.” — Matthew 6:33
________________________________________
To burn for the Kingdom is to make God’s purposes the central focus of life. It is to seek His will above all else and to live in obedience to His Word.
This kind of devotion brings fulfillment and joy. It aligns the believer’s life with God’s eternal purposes.
Those who burn for the Kingdom become instruments of God’s work on earth. They bring light into darkness and hope into despair.
Their lives become testimonies of God’s power and love.

Summary
Every person is driven by some form of inner fire. This fire may originate from the flesh or from the Spirit.
Strange fire leads to emptiness and destruction, while divine fire leads to life and fulfillment. Believers are called to reject the fires of carnality and to embrace the fire of divine desire.
Through vigilance and obedience, they can remain on the path that God has prepared.
