Charles Spurgeon Commentary John 21:1-3

"After these things Jesus manifested himself again to the disciples at the sea of Tiberias; and he manifested [himself] on this wise. There was together Simon Peter, and Thomas called Didymus, and Nathanael of Cana in Galilee, and the [sons] of Zebedee, and two other of his disciples. Simon Peter saith unto them, I go a fishing. They say unto him, We also come with thee. They went forth, and entered into the boat; and that night they took nothing." — John 21:1-3 (ASV)

After these things Jesus shewed himself again to the disciples at the sea of Tiberias; and on this wise shewed he himself. There were together Simon Peter, and Thomas called Didymus, and Nathanael of Cana in Galilee, and the sons of Zebedee, and two other of his disciples. Simon Peter saith unto them, I go a fishing. They say unto him, We also go with thee.

They could not do better. Idleness is the most injurious condition in which a man can be found. A preacher is much better occupied fishing than doing nothing.
