1 Thessalonians 3
3remembering before our God and Father your work of faith and labor of love and steadfastness of hope in our Lord Jesus Christ.
"Your work of faith"--is better translated, "their work produced by faith." "Work" is the Greek ergon, which refers to "a work, a deed, action, or accomplishment." It is "work" (singular) not "works" (plural) and seems to look at a specific work or deed performed.
The Thessalonians were acting out their faith in works of compassion and mercy. But here Paul is probably referring to their bold preaching of the gospel in the midst of persecution (1:8).
"Your labor of love"--is better translated, "their labor prompted by love.""Labor" is the Greek kopos, which refers to "laborious toil, trouble, difficulty." The labor of love is a present labor and is explained in verse 9, "to serve the living and true God." The objects of this love were the other members of the Christian community. -Berean Bible Church
