A.T. Robertson Commentary Romans 6:23

"For the wages of sin is death; but the free gift of God is eternal life in Christ Jesus our Lord." — Romans 6:23 (ASV)

Wages (οψωνια). Late Greek for wages of soldier, here of sin. See on Lu 3:14; 1 Corinthians 9:7; 2 Corinthians 11:8. Sin pays its wages in full with no cut. But eternal life is God's gift (χαρισμα), not wages. Both θανατος and ζωην are

eternal (αιωνιον).
