'End of This Age' in the Bible

'As, then, the darnel is gathered up, and is burned with fire, so shall it be in the full end of this age,

And when he was upon the mount of Olives, the disciples came to him in private, and said, tell us when shall these things be? and what shall be the sign of thy coming, and of the end of this age?

Children, it is the last hour [the end of this age]; and just as you heard that the antichrist is coming [the one who will oppose Christ and attempt to replace Him], even now many antichrists (false teachers) have appeared, which confirms our belief that it is the last hour.
