And when he had finished speaking, he said to Simon, “Put out into the deep and let down your nets for a catch.” Luke 5:4
The builder and sustainer of the Church, the Body of Christ is the Lord Jesus, not any man (Matt. 16:18). The building of the true Church is accomplished as God works through the foolishness of preaching to draw people from the darkness into the light and life that is found in Christ alone. It is built up in Christ through the means of grace, which are ordained by God not men. While we see that it is God who actually is doing the building, He has chosen to work through His servants to accomplish that which will bring Him glory. These servants that He uses as fishers of men are symbolically like the fishermen in their boats on the Sea of Galilee who cast their nets to catch fish to sell as their business.
