'Pouring out the vials upon the earth, which contained the plagues,' in Revelation 16:1, signifies influx of the reformed into the church, or into people who study and receive the doctrine of justification by faith alone.

(Odkazy: Apocalypse Explained 16; Apocalypse Revealed 676)

891. 21:8 "But the fearful, faithless, and abominable." This symbolizes people who have no faith and no charity, and are consequently caught up in evils of every kind.

The fearful symbolize people who have no faith, as will be seen next. The faithless symbolize people who have no charity toward the neighbor, for they are dishonest and deceitful, thus faithless. The abominable symbolize people who are caught up in evils of every kind, for abominations in the Word symbolize in general the evils listed in the last six of the Ten Commandments, as can be seen in Jeremiah:

Do not trust in lying words, saying, "The temple of Jehovah, the temple of Jehovah, the temple of Jehovah are they... Will you steal, murder, commit adultery, and swear falsely..., and then come and stand before Me in this house...(while you) do... these abominations?" (Jeremiah 7:2-4, 9-11)

And so also everywhere else.

That the fearful symbolize people who have no faith is clear from the following:

(Jesus said to His disciples,) "Why are you fearful, O you of little faith?" (Matthew 8:26, cf. Mark 4:39-40, Luke 8:25)

(Jesus said to the ruler of the synagogue,) "Do not be afraid; only believe, then (your daughter) will be made well." (Luke 8:49-50, cf. Mark 5:36)

Do not fear, little flock, for it is your Father's good pleasure to give you the kingdom. (Luke 12:32)

The same are meant by those told not to be afraid in Matthew 17:6-7; 28:3-5, 10; and elsewhere.

It can be seen from all these passages that the fearful, faithless, and abominable symbolize people who have no faith and no charity, and who are consequently caught up in evils of every kind.
