Do you not say, “There are still four months and then comes the harvest’? Behold, I say to you, lift up your eyes and look at the fields, for they are already white for harvest! And he who reaps receives wages, and gathers fruit for eternal life, that both he who sows and he who reaps may rejoice together. For in this the saying is true: ‘One sows and another reaps.’ I sent you to reap that for which you have not labored; others have labored, and you have entered into their labors.”(John 4:35-38)

God has left a witness in the earth. He has sent a multitude of prophets to testify of the grace that would come in the new covenant. He sent His own Son who came preaching “the kingdom of heaven is at hand.” Jesus sent apostles and more to preach the gospel into every creature. And now a multitude which no man can number has participated and entered into this ministry of reconciliation. So, take this good word and beseech any hearers to be reconciled to God. Today is the day of salvation and the day of harvest is coming. 

Revelation 14:15-16 

And another angel came out of the temple, crying with a loud voice to Him who sat on the cloud, “Thrust in Your sickle and reap, for the time has come for You to reap, for the harvest of the earth is ripe.” So He who sat on the cloud thrust in His sickle on the earth, and the earth was reaped.
