We Must Be Born Again of Water and the Spirit
God, when He created the heavens and the earth in the beginning, also created the eternal worlds, Heaven and hell. He created mankind in His own image, but, since the first man, Adam, sinned before God, all people have to die once. "And as it is appointed for men to die once, but after this the judgment" (Hebrews 9:27).
The death of our flesh is the passageway to eternal life. Those who are without sin shall enter the eternal world of Heaven and everlastingly enjoy being the children of God, while sinners will be thrown into "the lake of fire and brimstone" (Revelation 20:10) and be tormented day and night for all eternity.
