Now as he walked by the sea of Galilee, he saw Simon and Andrew his brother casting a net into the sea: for they were fishers.…
1. Their calling had inured them to hardship and danger — the lake on which they exercised their craft being exposed to sudden and violent storms.
2. Their calling, demanding a constant exercise of patience and watchfulness, and being very precarious besides, had made them familiar with disappointment, so that they would not be discouraged by it. Thus their worldly calling would be the best discipline for their spiritual work. They must be prepared to endure hardness, for they had no settled incomes; they must be ready to face death, for at any moment a storm of bloody persecution might arise; they must be patient, both towards churches and souls; and they must be content at times with taking a few converts in their nets, where they might have expected abundant draughts.
(M. F. Sadler, M. A.)
