Bible Cafe isn't just Bible study — it's a personal, intimate conversation with Him. Think less classroom, more kitchen table. It combines the original Coffee with Jesus experience with activities like quizzes, crosswords, journaling and more, all designed to let the Word shape your heart, not just your head.
Most English Bibles can't carry the full weight of what's in the original Hebrew and Greek. The F.O.G Bible Project exists to change that — three new translations built publicly (a Study Bible, a Reader's Bible, and F.O.G Jr. for younger readers), plus a word-by-word renewal of Strong's Concordance restoring the depths most translations leave behind. It is Jean Paul's lifelong work, unfolding in public — and you're invited in.
Jean Paul Joseph is the lead editor of the F.O.G Bible Project. He works from a personal encounter with Jesus first, then draws on the scholarship of respected Jewish and Christian scholars — because the church was Jewish before it was anything else, and those roots change everything about how you read Scripture.

The Turning That Unmakes the Mind
There is a moment, beloved reader, when a soul is so overturned that it no longer inhabits itself. The Greek verb peritrépō — appearing but once in all of Holy Scripture — captures this terrible and wondrous reality. Only one usage in the New Testament, yet that single occurrence trembles with the weight of divine judgment. The word means to turn around, to spin a person until their reason departs, to make them mad in the eyes of men. The KJV translators rendered it as “make mad,” but the Hebrew ear hears something deeper: the turning of a vessel until its contents spill out, and what remains is not the same as what was poured in.
The First and Only Occurrence: Paul Before Festus
You find this verb in the book of Acts, chapter twenty-six, verse twenty-four. The apostle Paul stands bound before Porcius Festus, the Roman governor, and speaks of the resurrection of the dead, of a light from heaven brighter than the sun, of a voice that spoke in Hebrew. Festus, a man of Roman reason and legal order, cannot contain himself. He cries out with a loud voice: “Paul, you are mad! Your great learning has turned you to madness!” The Greek phrase is eis manian peritrépei — your learning has turned you around into frenzy.
Here is the irony that would make the sages smile. The one who had once persecuted the Way, who had breathed threats and murder against the disciples, now stands accused of losing his mind for the very truth he once sought to destroy. The turning of Paul was not a madness of the brain but a conversion of the soul. Yet to the world, the turning of peritrépō looks like insanity. The rabbis of old observed that when a man encounters the Holy One, his former categories collapse. What the world calls reason, the Spirit may call rebellion. What the world calls madness, heaven may call the beginning of wisdom.
The Grammar of Divine Overturning
Consider the grammatical form of this verb in its sole New Testament appearance. It is present active indicative — peritrépei — a continuous, ongoing action. Festus does not say “you have become mad” as a completed state, but “you are being turned mad,” as if Paul’s very testimony is a force that keeps spinning him into a new reality. The present tense reveals a process, not a verdict. The action of peritrépō in this moment is not something Paul does to himself, but something the truth does to him through Paul’s proclamation.
Yet look deeper. The word is composed of peri, meaning around, and trepō, meaning to turn. This is the same root that gives you tropos — manner, character, turning. The classical Greeks used peritrépō to describe the act of turning someone’s mind, often with violent or magical connotations. But the Septuagint gives you a different story. In the Greek translation of the Hebrew Scriptures, this verb appears to translate the Hebrew hafakh — to overturn, to transform, to change utterly. When the Lord overturned Sodom and Gomorrah, the Septuagint uses a form of this same root. The turning of peritrépō is not merely confusion — it is divine judgment and transformation intertwined.
The Hebrew Bridge: From Overturning to Revelation
Let us cross the bridge between languages, for every Greek word in the New Testament carries the echo of a Hebrew original. The Septuagint uses peritrépō to translate hafakh in passages of profound upheaval. In the book of Lamentations, the prophet cries that the Lord has turned (hafakh) his glory into shame. In the Psalms, the righteous man sees the Lord turning the ways of the wicked upside down. But the most striking is the account of Balaam in Numbers chapter twenty-two. When the angel of the Lord stood in the way as an adversary, Balaam’s donkey turned aside — the same root of overturning.
What does this tell you, dear seeker? The turning of peritrépō is not random chaos but purposeful upheaval. When Festus accused Paul of madness, he was witnessing the overturning of a persecutor into a preacher, of a Pharisee into an apostle, of a man who guarded cloaks at the stoning of Stephen into a man who would be stoned himself. The ancient writings of Israel teach that when the Holy One turns a soul, He does so with precision — every thread of the old garment is torn so that a new one may be woven. Your own turning may feel like madness, but it is the work of the Master Weaver.
The Apostolic Pattern: Paul and the Madness of the Cross
The apostle Paul understood this turning better than any other New Testament writer. Though this verb appears only once in his recorded words (through Luke’s account), the concept permeates his letters. He writes to the Corinthians that the message of the cross is foolishness to those who are perishing, but to those being saved, it is the power of God. He declares that if anyone among them thinks they are wise in this age, they must become fools to become truly wise. This is peritrépō applied to the mind — a deliberate overturning of human wisdom by divine revelation.

The early church understood this pattern. Clement of Rome, writing to the Corinthians, described how the apostles were “turned around” from their former lives by the resurrection. Ignatius of Antioch, on his way to martyrdom, wrote that he was “the wheat of God” and that he must be ground by the teeth of wild beasts to become pure bread. This is the madness of faith — not a loss of intellect, but a surrender of self-will to the One who turned the universe from chaos into order. The apostolic tradition teaches that every true disciple must experience some measure of peritrépō — a turning so complete that the old mind cannot recognize the new.
Messianic Fulfillment: Yeshua and the Overturning of the World
Now lift your eyes to the Messiah Himself. Did not Yeshua experience the accusation of madness? In the Gospel of Mark, chapter three, verse twenty-one, His own family came to seize Him, saying, “He is out of His mind.” The Greek there is different — exestē, meaning to stand outside oneself — but the pattern is the same. The Son of God, who healed the sick and cast out demons and forgave sins, was called insane by those who loved Him. The sages teach that when a man speaks the truth of heaven on earth, earth will call him mad.
But Yeshua did not merely endure the accusation of madness — He fulfilled the deeper meaning of peritrépō. He turned the tables of the money changers in the temple. He turned water into wine. He turned the hearts of the disobedient to the wisdom of the just. And on the third day, He turned death itself into a doorway. The resurrection is the ultimate peritrépō — the turning of the grave from an end into a beginning, from a prison into a passage. Every soul that follows Him must be turned in the same way. The Messiah does not merely teach you new information; He turns your entire orientation. What you once called life, you must now call death. What you once called madness, you must now call the only sanity there is.
The Septuagint Echo: Madness as Prophetic Calling
Let us descend one level deeper into the Septuagint cross-reference. The verb peritrépō appears in the Greek translation of the prophet Hosea, chapter nine, verse seven: “The prophet is a fool, the spiritual man is mad (peritrépō), because of the multitude of your iniquity.” Here you find the Hebrew meshugga, the same word used when the Philistines called David mad, and when the prophets of Baal were called mad by Elijah. The LXX translators chose peritrépō to describe the prophetic state — a man so overtaken by the Spirit of God that he appears insane to those who dwell in rebellion.
This is the heritage of every believer. When the Spirit of the Lord comes upon you, you will be turned. The Greek philosophical tradition, from Plato to the Stoics, valued reason above all — the logos as the rational principle of the universe. But the biblical tradition reveals a God who overturns reason to reveal a higher wisdom. The apostle Paul, the most educated man of his generation, was turned from a scholar of the law into a herald of the cross. Your education, your learning, your carefully constructed worldview — all of it must be turned by the same Spirit. The early church fathers observed that faith is not the enemy of reason but its fulfillment, yet the path to that fulfillment passes through the valley of apparent madness.
Your Calling: Let Yourself Be Turned
And now, beloved, the question lands upon your own soul. Have you been turned? Has your life experienced the peritrépō that the Spirit works in those who belong to the Messiah? You may resist this turning, clinging to the reason of this age, fearing what others will say when they call you mad. But consider: what is the alternative? To remain unturned is to remain unbroken, and to remain unbroken is to remain unhealed. The world’s reason cannot save you; it can only explain your chains. The turning of the Spirit may look like madness to Festus, but to Paul it was the only freedom he had ever known.
Let the same Spirit that turned Saul into Paul, that turned the disciples from fishermen into fishers of men, that turned the tomb into an empty sign of victory — let that Spirit turn you. Do not fear the dizziness of the turning. Do not fear the loss of the person you used to be. For the One who turns you is the same One who holds the universe in its orbit, who turns the seasons, who turns the heart of the king like water in His hand. Your madness in the eyes of men is your sanity in the presence of God. Let yourself be turned, and you will find that you have not lost your mind — you have finally found it.
