Jesus explains in detail the events that took place at the beginning and will transpire at the end, saying:
“He that soweth the good seed is the Son of man; the field is the world; the good seed are the children of the kingdom; but the tares are the children of the wicked one; the enemy that sowed them is the Devil; the harvest is the end of the world; and the reapers are the angels. As therefore the tares are gathered and burned in the fire; so shall it be in the end of this world. The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; and shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. Then shall the righteous shine forth as the sun in the kingdom of their Father” (Matthew 13:37–43).
“I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty. Behold, he cometh with clouds; and every eye shall see him, and they also which pierced him: and all kindreds of the earth shall wail because of him. Even so, Amen” (Revelation 1:8-9).
