In his
defence of amillennialism (what he calls “non-millennialism”), W.J.
Grier, an Irish Presbyterian theologian, wrote the following about the problems with postmillennial views:
It may be objected to this view, and we feel
there is some force in the objection, that the Bible does not hold forth the
prospect of a converted world before the Lord comes; are not the wheat and the
tares to grow together till the harvest at the end of the world Moreover, it
does not quite seem to harmonise with the idea of a millennium of prevailing
righteousness that, at its close, Satan will be found leading a host to battle from the four quarters of the earth,
whose number is as the sand of the sea (Rev. 20:8). Where are they to come from,
if righteousness prevails in a converted world (Cp. Luke 18:8; II Thes.
2:1-12)? (W.J. Grier, The Momentous
Event: A Discussion of Scripture Teaching on the Second Advent [Edinburgh:
The Banner of Truth Trust, 1970], 13)
