The Gospel of Philip 82
2[Most (things)] of [the] world can stand up and live as long as their [insides are hidden. If they're revealed], they die, as [illustrated] by the visible human. [As long as] the human's guts are hidden, the human is alive. If their guts are exposed and come out of them, the human will die. It's the same way with the tree. While its root is hidden, it blossoms and grows. If its root is exposed, the tree dries up. That's what it's like with everything that's born in the world, not only the revealed, but also the hidden; because as long as the root of evil is hidden, it's strong. But if it's recognized, it dissolves, and if it's revealed, it dies. So the Word says, "Already the axe is laid at the root of the trees." It won't (just) cut, (because) that which will be cut blossoms again. Rather, the axe digs down into the ground until it brings up the root. Jesus plucked out the root completely, but others did so partially. As for us, let every one of us dig down to the root of the evil within and pluck it out from its root in us. It'll be uprooted if we recognize it. But if we don't recognize it, it takes root within us and bears its fruit in us. It masters us, and we're forced to serve it. It captures us so that we do what we do [not] want to; and we do [not] do what we want to. [It's] powerful because we haven't recognized it. It's active as long as [it exists]. [Ignorance] is the mother of [all evil]. Ignorance will cause [death, because] what exists from [ignorance] neither did exist nor [does exist], nor will they come into being […] they'll be perfected when the whole truth is revealed, because the truth is like ignorance. When it's hidden, it rests within itself, but if it's revealed and recognized, it's glorified inasmuch as it's stronger than ignorance and error. It gives freedom. The Word says, "If you'll know the truth, the truth will make you free." Ignorance is slavery; knowledge is freedom. If we know the truth, we'll find the fruits of truth within us. If we unite with it, it'll receive our fullness.
