Millennium
Throoughout the Scriptures, Satan is said to exert great power not only against the
world but also against Christians (Acts 5:3; 1 Cor. 5:5; 7:5; 2 Cor. 2:11; 11:14; 12:7;
1 Tim. 1:20). If there is still any question whether this is so, it should be settled
by the exhortation of 1 Peter 5:8: "Be self-controlled and alert. Your enemy the devil prowls
around like a roaring lion looking for someone to devour.
(The Bible Knowledge Commentary, p. 979 )
The millennial age is to be the age in which divine righteousness is to be displayed
(Isa. 11:5; 32:1; Jer. 23:6; Dan. 9:24). It is also to be God's final test of fallen
humanity under the most ideal circumstances. All outward sources of temptation must
be removed so that man will demonstarte what he is apart from Satanic influence. So
that there can be the full manifestation of righteousness and a test of
humanity apart from external temptation, Satan must be removed from the sphere. Therefore,
at the second advent (coming) [of Christ] he (Satan) will be bound and removed from
the scene for the entirety of that millennial period. (Things to Come, p. 477)
The millennium is not a timeperiod to test mankind in order to find out the goodness of
humanity. The goal is not to prove ourselves worthy of salvation. To the contrary,
by the time the 1000 years are over, it will be plain that mankind cannot altogether blame
our sinful acts of rebellion upon the devil. "The devil made me do it" is sometimes heard
today and usually by those who wish not to take any part of the responsibility for their
own sinful thoughts and desires. During the millennium, it will be plain to all: humanity
has a fallen nature, and apart from becoming a new creature (i.e., born again), we cannot
do what is good in the eyes of God.
The millennial age is designed by God to be the final test of fallen humanity under the
most ideal circumstances, surrounded by every enablement to obey the rule of the king,
from whom the outward sources of temptation have been removed, so that man may be found
and proved to be a failure in even this last testing of fallen humanity. (Things to Come, p. 538)
