The Greek adverb allōs means 'otherwise,' 'in another way,' or 'differently.' Derived from allos (G243, 'another'), it appears once in the New Testament — in 1 Timothy 5:25 — where it qualifies the eventual visibility of good and bad works.
The single New Testament use of allōs in 1 Timothy 5:25 carries quiet pastoral wisdom: 'good deeds are obvious, and even those that are not obvious cannot remain hidden' (allōs). What is done truly, even when unnoticed by others, will be rewarded.
This adverb points to the accountability structure of the Christian life. The judgment seat of Christ (2 Corinthians 5:10) is the ultimate context: what is hidden now will be made manifest. The reverse is also true — hidden sin will also be exposed.
