The Greek word for laborers here is ἐργάτης (ergatēs). ἐργάτης means “someone who does something” (Mounce’s Complete Expository Dictionary) With this reasoning, what this passage is really saying is “The harvest is plentiful – there are a lot of people out there ready to receive Christ. But there’s hardly anyone out there who is doing something to reap that harvest.” Ouch. Am I a worker? Am I doing something? Am I doing something to reap this huge harvest? Am I doing something to advance the kingdom of God?
2 Timothy 2:15 uses this same word ἐργάτης when he writes “Be diligent to present yourself approved to God as a workman who does not need to be ashamed, accurately handling the word of truth.” This is the kind of worker we are called to be as missionaries, as Bible translators, as mothers, as daughters, as a Church. This is the kind of ἐργάτης I am called to be right here, right now, by the power of the Holy Spirit Who lives in me.
Father, make us a ἐργάτης who does not need to be ashamed. Make us workers who accurately handle Your truth, and make us workers who do something for Your kingdom and glory. Open our eyes to see Your harvest and then move us to reap it. Fill us with Your Spirit so that we may do the work You have called us to do and make us faithful in prayer and faithful in fulfilling Your command to be diligent to do. We praise You because You are so faithful to fill us with the power to do the things which You have asked of us. We praise You because You are very near and are powerful beyond our comprehension. Amen.
