Herbert Kane well summarized:
The Bible clearly teaches that there are two destinies open to man. One involves everlasting happiness in the presence of God and the holy angels (Lk 15:10; Rev 22:3–5; 1 Thess 4:17), the other involves everlasting misery in the company of the devil and his angels (Mt 25:41).
The New Testament speaks of two gates—one strait and the other wide; two ways—one broad and the other narrow; two destinies—one life and the other destruction (Mt 7:13–14).
In the day of judgment the sheep will be separated from the goats (Mt 25:31–46), and the wheat from the tares (Mt 13:36–43), the good from the evil (Jn 5:29). And in the resurrection there will be a separation between the just and the unjust (Acts 24:15)
