I serve (latreuw). Old verb from latron, hire, and latri, hireling, so to serve for hire, then to serve in general gods or men, whether sacred services ( Hebrews 9:9 ; Hebrews 10:2 ) or spiritual service as here. Cf. Romans 12:1 ; Philippians 3:3 . Unceasingly (adialeiptw). Late adverb for which see 1 Thessalonians 1:2 ; 1 Thessalonians 2:13 ; 1 Thessalonians 5:17 , only other N.T. examples. Always (pantote). One might think that Paul prayed for no others, but he uses both adverbs in 1 Thessalonians 1:2 . He seems to have had prayer lists. He never omitted the Romans.
