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 Watchman Who Becomes the Kept One
Beloved, hear the sound of this sacred verb — phylássō — which appears thirty-two times in the New Testament, each occurrence a bell tolling the vigilance of heaven. It is a word that begins as a command to keep watch, but ends as a promise that you are kept. The first time the apostolic witness sounds this verb, it is in the mouth of the Master Himself, speaking of treasure where moth and rust do not consume and where thieves do not break through to steal. Yeshua said, “Do not store up for yourselves treasures on earth… but store up for yourselves treasures in heaven.” And then He added the weight of this verb: “For where your treasure is, there your heart will be also.” The watching and the keeping are one movement — you guard what you love, and what you love guards you.
The Isolation That Protects
The sages of old observed that the root of phylássō carries the sense of isolation, of setting something apart for its safety. It comes through the idea of a tribe, a phylē, a people set apart by covenant. To guard, in the biblical imagination, is not merely to stand watch with a weapon — it is to sanctify. When the psalmist cries out, “Keep me as the apple of the eye,” the Septuagint renders that Hebrew verb with phylássō. The apple of the eye is the most tender, the most vulnerable, the most precious part — and it is isolated by the eyelid, protected by the brow, defended by the whole face turning away from harm. The apostolic tradition teaches that this is how the Holy One guards His people: not by distant observation, but by intimate enclosure. You are not merely watched; you are wrapped.
The Grammar of Divine Vigilance
Consider the tenses in which this verb appears, for the grammar itself is a sermon. When Paul writes to the Thessalonians, he uses the perfect tense: “The God of peace Himself sanctify you wholly, and may your whole spirit and soul and body be preserved (phylachtheiē) blameless at the coming of our Lord Yeshua Messiah.” The aorist passive here speaks of a completed action — you are kept by a power not your own, once and for all. Yet elsewhere the present imperative appears: “Watch and pray,” the Lord commands in the garden. The present tense means continuous, habitual, unrelenting vigilance. The paradox is this: you must keep watch because you are already kept. The early church understood this tension perfectly — they knew that the Good Shepherd keeps the sheep, and yet the sheep must not wander. The classical Greek world spoke of phylássō as the guard duty of a soldier, but the apostolic faith transformed it into the posture of a beloved child holding the Father’s hand.
The Septuagint Bridge: From Hebrew Vigil to Greek Keeping
When the translators of the Septuagint sought a Greek word to carry the Hebrew shamar — that ancient command to keep, to guard, to observe — they chose phylássō time and again. The first occurrence of shamar in the Hebrew Scriptures is in the garden: “The Lord God took the man and put him into the garden of Eden to dress it and to keep (shamar) it.” The Septuagint writes phylássein. Adam was not merely a gardener — he was a guardian of sacred space, a watchman over the dwelling place of the Presence. When the Lord commands Abraham to “keep My covenant,” the Septuagint again uses phylássō. The Hebrew word carries the scent of the thorn hedge, the watchtower, the careful counting of the sheep at evening. The Greek translators captured this: to keep is to surround with attention, to hold with intention. Every time you read “keep” in the Greek New Testament, you are hearing the echo of Eden’s first calling — you are placed in a garden to guard it, and you are guarded by the Gardener Himself.

The Apostle Who Wrote of Keeping
The apostle John uses this verb more than any other New Testament writer — seventeen times in his Gospel and letters. This is the beloved disciple, the one who leaned on the Master’s breast, and his soul was shaped by the keeping love of Yeshua. John records the Lord’s prayer in the garden: “Holy Father, keep (phylássō) them through Your name which You have given Me.” Here the verb takes on its deepest hue — the keeping is through the Name. The Name of the Holy One is not a label but a reality, a shelter, a strong tower. To be kept through the Name is to be hidden in the identity of God Himself. John also writes in his first letter: “He who is begotten of God keeps (phylássei) himself.” The middle voice appears here — you keep yourself, but only because you have first been kept. The early church father Ignatius, walking the road to his martyrdom, wrote to the Romans: “I am the wheat of God, and I am ground by the teeth of wild beasts that I may be found pure bread of Christ.” He knew that the keeping power of God does not always preserve the body, but always preserves the soul. The apostolic tradition teaches that to be kept by God is to be made ready for whatever comes.
The Messianic Keeping: Yeshua as the Guardian of Israel
The New Testament writers apply this verb to Messiah in a way that transforms every other use. Paul writes to Timothy, “I know whom I have believed, and am persuaded that He is able to keep (phylássō) that which I have committed to Him against that day.” The deposit — the parathēkē — is your very life, your faith, your hope, your soul’s treasure. Yeshua is not merely a watchman who guards from outside; He is the One who receives what you entrust and holds it within Himself. Jude writes a doxology that thrills the heart: “Now to Him who is able to keep (phylássō) you from stumbling and to present you faultless before the presence of His glory with exceeding joy.” The keeping here is not merely defensive but triumphant — you are kept from falling, and you are presented as a gift. The rabbis of old observed that the Messiah would be called “the Keeper of Israel” — the One who neither slumbers nor sleeps, the Watcher whose eyes run to and fro throughout the earth. In Yeshua, this keeping becomes personal: He keeps you by name, by breath, by the blood He poured out.
Your Calling to Keep and Be Kept
And now, beloved, what of you? The verb phylássō stands before you as both command and promise. You are called to keep the faith — not as a grim duty, but as a bride treasures her wedding ring. You are called to keep yourself from idols — not by grimacing at the world, but by gazing at the beauty of the One who first kept you. The apostolic tradition whispers this secret: the keeping of the commandments is not the burden of the law but the joy of the beloved. When you keep His word, you are not earning His love — you are abiding in it. So let this word become your breath today. Watch, keep, guard, preserve — not in your own strength, but in the strength of the One who keeps you as the apple of His eye. The night is far spent, the day is at hand. Put on the armor of light, and let the Keeper of Israel keep your going out and your coming in, from this time forth and forevermore.
