Study Lenses
The verse centers on "fear", "love", "perfect", "casts", and "punishment". It is saying that the verse draws attention to "fear" and "love", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 17's "In this love has been made perfect..." into verse 19's "We love him because he first loved...", so "fear" and "love" belong inside that flow. In 1 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "fear" and "love" with trust shaped by these words, not by a vague optimism outside the passage.
