<p>1:19 <em>And going on a little further, he saw James the son of Zebedee and John his brother, who also were in the boat</em>- The reference to a specific boat suggests that they had been in the boat from which Simon and Andrew had been casting their nets (:16).</p><p><em>Mending the nets</em>- Which were presumably damaged. The implication was that the Lord would give them nets which would not break- the work of the Gospel will always succeed, ultimately. Hence the later acted parable of the nets which did not break despite the 153 fishes caught (Jn. 21). We can assume that they had just had a good catch, hence the need to mend their nets. It was at the peak of their career success, as it were, when they were feeling good about their work... that the Lord asked them to leave it all for Him.</p>
