There are 3 destinies among the saved....but only one is concerning the saints who rule with Christ
Zech. 13:8 And it shall come to pass in all the land,”
Says the Lord,
“That two-thirds in it shall be cut off and die,
But one-third shall be left in it:
9 I will bring the one-third through the fire,
Will refine them as silver is refined,
And test them as gold is tested.
They will call on My name,
And I will answer them.
I will say, ‘This is My people’;
And each one will say, ‘The Lord is my God.’ ”
Paul was afraid of being cut-off...but cut-off from what..or Whom? From the presence of the Lord. Without holiness none shall see the Lord.
The word in Hebrew for "die" in v.8 is to "breathe out". Sort of sounds like being spit out of the mouth of Jesus. But the death is separation from God....not a lack of life.
