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 Color of Heaven's Throne
There is a shade that dwells between earth and sky, a hue that appears only once in all the sacred writings—hyakínthinos, the color of deep blue, the shade of jacinth. In the Revelation given to Yochanan, this single word appears like a jewel set in the foundation of the New Yerushalayim, and its rarity is its power. The Holy Spirit does not waste words; when He speaks but once with a color, that color carries the weight of eternity. The number of its occurrence is one, and that oneness echoes the singularity of the throne it adorns.
From Flower to Foundation
This word springs from hyákinthos, the name of a flower whose petals bore the deepest blue of the Mediterranean sky at twilight. The Greeks knew this flower, and they knew its dye—a precious pigment extracted with labor, worth its weight in silver. But when the inspired writer of Revelation reached for this adjective in the twelfth chapter of that great unveiling, he was not merely describing a gemstone's color. He was reaching back through the Septuagint, where this same word translated the Hebrew techelet, the sacred blue of the Tabernacle's curtains and the priest's garments. In the scroll of Exodus, the Lord commanded that the loops of the Tabernacle covering be made of techelet (Exodus 26:4), the very blue that would later adorn the high priest's robe and the fringes of every Israelite's garment. The rabbis of old observed that this blue was the color of the sea, which is the color of the sky, which is the color of the sapphire throne of the Holy One. What began as a flower's name became, through the furnace of Scripture, the very color of divine presence.
The Foundation That Holds the City
In the twenty-first chapter of Revelation, as Yochanan describes the New Yerushalayim descending from heaven, he speaks of foundations adorned with every precious stone. The eleventh foundation is hyakínthinos, and the apostolic tradition teaches that this is the jacinth—a stone of deep blue, sometimes flashing with fire. The early church understood that these foundations were not merely decorative; they were the very truths upon which the people of God are built. Each stone reflects a facet of the Messiah's glory, and the jacinth foundation speaks of heavenly authority and priestly intercession. For just as the high priest of old wore the techelet upon his robes when he entered the Holy of Holies, so the foundation of jacinth supports the city where the High Priest forever dwells. The writer of Hebrews tells us that Yeshua has passed through the heavens, not with the blood of goats and calves, but with His own blood (Hebrews 9:11-12). The blue of the foundation whispers that this city is built upon His priesthood.
The Bridge Between Two Testaments
When the translators of the Septuagint rendered the Hebrew Scriptures into Greek, they faced a sacred task: to carry the weight of revelation from one tongue to another. For the word techelet, they chose hyakínthinos in the book of Exodus, describing the yarns woven into the Tabernacle's fabric (Exodus 25:4). This is no accident. The same color that veiled the Holy Place in the wilderness now appears as the foundation of the eternal city. The bridge between the two covenants is built of this very blue—the color that once separated the holy from the most holy now becomes the bedrock upon which all the redeemed stand. The rabbis of old taught that the techelet in the tzitzit, the fringes, reminded Israel of all the commandments. But here, in the Revelation, the hyakínthinos foundation reminds the faithful of something greater: that the commandments have been written not on stone, but on the hearts of those who dwell in this city. The color that once pointed to the law now points to the law's fulfillment.

Yeshua, the Foundation and the Color
The Messiah is not merely the one who reveals the meaning of this word—He is the reality that the word signifies. In the vision of Yochanan, Yeshua appears with feet like burnished bronze, eyes like a flame of fire, and a voice like many waters (Revelation 1:14-15). But it is in the heavenly throne room that the connection becomes clearest: the One who sits upon the throne has the appearance of jasper and sardius, and around the throne is a rainbow like an emerald (Revelation 4:3). The hyakínthinos foundation is part of this spectrum of divine glory. The apostolic faith teaches that Yeshua is the chief cornerstone, the foundation upon which all other foundations rest. He is the blue of the priestly garment and the blue of the heavenly city, for He is both the High Priest who intercedes and the King who reigns. In His person, the Tabernacle and the Temple find their ultimate meaning; in His blood, the veil is torn, and the blue curtain becomes the open door.
The Single Thread of Testimony
That this word appears only once in the New Testament is a lesson in itself. The Holy Spirit does not scatter treasures carelessly; He places them where they will be found by those who search. The single occurrence of hyakínthinos calls you to consider the weight of divine economy—how every word, every color, every stone in Scripture is chosen with infinite precision. The fathers of the faith observed that the New Yerushalayim has twelve foundations, and each one bears the name of an apostle of the Lamb (Revelation 21:14). The jacinth foundation carries the name of one who witnessed the resurrection, one whose testimony was sealed with blood. You are being built into this city, stone by living stone, and the blue of the foundation is the color of the covenant faithfulness that holds you secure. The single thread of this word weaves through all of Scripture, from the Tabernacle to the Temple to the throne, and it finds its end in the heart of the city where the Lamb is the light.
Walking in the Color of Heaven
What does it mean for you to walk in the reality of hyakínthinos? It means to live as one who has seen the heavenly throne and knows that the blue of the priestly garment is the same blue that holds the foundations of your soul. You are called to be a living stone in a spiritual house, a holy priesthood offering spiritual sacrifices (1 Peter 2:5). The color of heaven is upon you—not as a dye that fades, but as the unshakable foundation of the One who has called you out of darkness into His marvelous light. When you pray, remember that you approach the throne where the jacinth gleams. When you suffer, remember that the foundation beneath you is eternal. When you worship, let the blue of the sky remind you that your citizenship is in heaven, and from it you await a Savior. The sages of old taught that the techelet was like the sea, and the sea like the sky, and the sky like the throne of glory. Now you know the One who sits upon that throne, and His name is Yeshua. Walk in the color of His covenant, and let your life be a foundation stone in the city that is to come.
