'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)

If we turn ourselves toward the Lord, we can get the full inflowing of His wisdom and love; if we turn away from Him we cast ourselves into cold and shadow -- we turn ourselves toward hell. In the Bible, "turning" generally refers to a change in spiritual state, as people turn themselves toward the Lord or away from the Lord.
