He that goeth forth and weepeth, bearing precious seed, shall doubtless come again with rejoicing, bringing his sheaves with him Psalm 126:6
God planted the best seed He had (His Son), and He is not going to quit on earth until He reaps a great harvest of precious souls. There’s a joy in the harvest we’ll not find anywhere else. There is joy of leading someone to Christ that is a joy like nothing else. Jesus told a parable in Luke 15 about a lost sheep, lost coin, and lost son. In each instance of finding what was lost it caused joy (Luke 15:7,10,32). I’ve never met a Christian discouraged because he had just led a person to the Lord! It gives rejoicing and joy unspeakable and full of glory.
