Question:
What is the Scripture referring to when it speaks of “the harvest?” Is it something Christians do now or it is something that will happen later?

Answer:
It seems that the word “harvest” is used in two ways in the New Testament.

 

One way is preaching the Gospel to the lost. Now is the opportune moment. The fields are white unto harvest and laborers are needed. See Matthew 9 and John 4, among others.

The second way is to depict God’s judgment of the lost. Matthew 13; Mark 4; and Revelation 14 speak of this.
