All evil flows from one heart, the heart of Lucifer and the first “No” to God’s plan. His “no” established the Kingdom of Darkness and was quickly filled by other angels who followed him.
Ever since, all evils have come from Lucifer’s heart. If not repented, they carry the person back into Satan’s heart which is now called hell.
When the Word became Flesh, the Father created another heart. Now the two hearts clash, both seeking followers. There is a third heart, the heart of the woman who conquers. All becomes clear. War has broken out in the heavens. Its flames fall daily upon earth. All must choose either Lucifer or the Woman.
