Passage
For no prophecy ever came by the will of man: but holy men of God spoke, being moved by the Holy Spirit.
For no prophecy ever came by the will of man: but holy men of God spoke, being moved by the Holy Spirit.
2 Peter 1:19 We have the more sure word of prophecy; and you do well that you heed it, as to a lamp shining in a dark place, until the day dawns, and the morning star arises in your hearts:
2 Peter 1:20 knowing this first, that no prophecy of Scripture is of private interpretation.
2 Peter 1:21 For no prophecy ever came by the will of man: but holy men of God spoke, being moved by the Holy Spirit.
The verse centers on "Spirit", "prophecy", "ever", "came", "holy", "spoke", and "moved". It is saying that the verse draws attention to "Spirit" and "prophecy", so its meaning should be read from those terms before moving to application.
The prior verse says "knowing this first that no prophecy of...", giving immediate footing for "Spirit" and "prophecy". In 2 Peter context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "Spirit" and "prophecy" with trust shaped by these words, not by a vague optimism outside the passage.
