INTRODUCTION

When Bro. Aldrich and some of our Fiji team went up to Togovere Hill, we couldn’t help but ask ourselves: How can anyone look around and think there is no God?

The majestic mountains laid out before us, the expansive sea, the shifting clouds, and every living creature speak clearly of the invisible God. What amazed us most was watching how the fruit trees produce their yield right on schedule. Not just one random tree, but every tree after its own kind, doing the exact same thing season after season. Creation operates under a divine order. There must be Someone caring for them, maintaining them, and sustaining them—and we know that Someone is God.

Yet, despite the obvious evidence in creation, many still struggle in their hearts. The most important thing about you is not who you are on the surface or what you can achieve. The most important thing about you is what you truly believe in the core of your being.

Why? Because what you believe determines your identity!

• People with behavioral problems ultimately have belief problems.
• If a person doesn’t believe right, he is not going to behave right.
• When a person behaves wrongly, it is because he is believing wrongly—he is clinging to something that is false or deceptive.

The Pattern of Unbelief:

• If a person believes there is no God, he will behave as if there is no God.
• If a person believes he can get away with sin, he will commit sin.
• If he believes a situation is hopeless, he will sink into despair.
• If a person believes prayer accomplishes nothing, he will cease to pray.

To correct misbehaviour, we must correct misbeliefs. We must stop believing a lie and start believing what is true.

I. FAULTY FAITH FOSTERS FOOLISH CONDUCT

Psalm 14:1 — “The fool hath said in his heart, There is no God…”

Wrong belief always leads to wrong living.

A. DENYING God Brings DECAY

Psalm 14:1a — “The fool hath said in his heart, There is no God.”

Notice where this denial starts—it does not begin in the intellect; it begins in the heart. In the Hebrew language, the word for “fool” (Nabal) refers to someone who is spiritually withered, dry, or sapless. A person rarely denies God for lack of evidence; they deny God because their heart wants to live without moral accountability. When you dethrone God from your heart, moral decay is inevitable. Just as a cut flower begins to wither the moment it is severed from its root, human character immediately rots when it cuts itself off from the Creator.

No God in the heart = No restraint in the life.

B. DOUBTING God Brings DECEPTION

Psalm 14:1b — “They are corrupt, they have done abominable works…”

The step after denying God is justifying evil. Satan’s oldest lie in the garden was, “Ye shall not surely die.” When a person doubts God’s holiness, His omniscience, or His judgment, they trick themselves into thinking sin has no price tag. Deception convinces a person that they are the rare exception to God’s warnings. But living in spiritual deception is like drinking salt water—it promises to satisfy your thirst, but it is secretly destroying you from the inside out.

What you excuse in belief, you will embrace in behavior.

C. DESPAIRING over God Brings DEFEAT

Psalm 14:1c — “…there is none that doeth good.”

When a person’s view of God is wrong, their view of their own circumstances becomes distorted. Unbelief paints every trial as terminal and every problem as permanent. If you believe God is indifferent to your pain or powerless to intervene, you will stop praying and surrender to hopelessness. Despair is the natural destination of a soul that has forgotten the goodness and sovereignty of God. A defeatist posture in life is almost always the child of a prayerless heart.

A hopeless belief creates a helpless life.

II. FAITHFUL BELIEF FOSTERS GODLY CONDUCT

Jesus asked three times: “Believest thou?” | Right belief always leads to right living.

A. ACKNOWLEDGE His ABILITY

Matthew 9:28 — “Believe ye that I am able to do this?”

When the two blind men came to Jesus, He didn’t ask about their qualifications, their past failures, or the severity of their condition; He asked about their conviction regarding His power. Unbelief looks at the size of the mountain and shrinks in fear; biblical faith looks at the God who moves mountains and steps forward. When you truly acknowledge that God is able, you stop measuring your future by your human limitations and start measuring it by His divine resources.

Faith in His power produces prayer and persistence

B. ACCEPT His AUTHORITY

John 9:35 — “Dost thou believe on the Son of God?”

Jesus is not merely looking for people to admire Him as a good teacher or a miracle-worker; He demands that we acknowledge Him as Lord. To believe in Him means to bow your will to His Word. Real faith doesn’t negotiate with Scripture or pick and choose which commands to follow. When your core belief shifts to “Jesus is Lord,” your behaviour naturally shifts from self-pleasing rebellion to joyful, Spirit-led obedience.

Faith in His authority produces obedience and surrender.

C. ANCHOR in His ASSURANCE

John 11:26 — “And whosoever liveth and believeth in me shall never die. Believest thou this?”

At the tomb of Lazarus, Jesus made a statement that redefined human destiny. Our anchor is not cast into the deepest sea, but is fixed in the highest heaven — in the Lord and Saviour Jesus Christ. For those anchored in Christ, physical death is not an ending—it is simply a doorway into eternal glory. When you are firmly persuaded of Christ’s promises and your eternal home, the threats, worries, and trials of this temporary world lose their grip on your heart. Assurance produces an unshakeable peace that allows you to stand firm when everything around you is shaking.

Faith in His promise produces peace and purpose.

CONCLUSION:

The fool says “There is no God” and lives like it.

The believer says “I believe God” and lives like it.

To correct misbehaviour, we must first correct misbeliefs. Stop believing the enemy’s lies and start standing firmly on God’s truth. Ask yourself these three heart-searching questions today:

A. What do you believe about God? Do you believe He is just a distant creator, or do you believe He is actively involved in your daily life? It is one thing to acknowledge God with your lips on Sunday; it is another thing to acknowledge Him in your choices on Monday. If you truly believe He is holy, sovereign, and present everywhere, it will change how you speak, how you act, and how you treat others when no one else is watching.

Is God real to you every single day, or only when you are inside the church?

B. What do you believe about sin? Do you see sin as a dangerous, life-destroying poison, or do you view it as a harmless mistake? The world tells us to excuse our wrongdoings, rename our faults, and justify our habits. But if you believe what the Bible says about sin—that it corrupts the heart, destroys families, and separates us from God—you will stop flirting with temptation and start fleeing from it.

Are you confronting the sin in your life, or are you constantly making excuses for it?

C. What do you believe about His promises? When the storms of life hit—when sickness comes, financial struggles arise, or grief knocks at your door—what holds you steady? If you believe God’s promises are true, you won’t throw away your faith when times get tough. You will stand on His Word knowing that He is faithful, He is able, and His promises never fail. Faith doesn’t mean you won’t face troubles; it means you trust the God who holds your future.

Are you anchoring your life on the unchanging truth of God’s Word, or are you letting fear and doubt dictate your peace?

Check your heart today. Because what you truly believe in your core will always determine who you become in your conduct.
