And going on from there, He saw another two brothers, James the son of Zebedee and John his brother, in the boat with Zebedee their father, mending their nets; and He called them.
When they were called by the Lord, they were mending their nets in the boat. When the Lord called them, they left the boat and their father and followed Him. John and his brother, like Peter and Andrew, were attracted by the Lord and followed Him. Eventually, John became a real mender, mending the breakages in the church by his ministry of life. (See his three Epistles and Revelation chapters two and three.)
