Not only did Christ reveal himself to these disciples while at their lowly work, but he helped them in it.
He told them where to cast their net, and turned their failure to success.

We think of Christ as helping us to endure temptation, to bear trial, to overcome sin, to do spiritual duties, but we sometimes forget that he is just as ready to help us in our common work.

That morning he helped the disciples in their fishing.

He will help us in our trade or business, or in whatever work we have to do.
We all have our discouraged days, when things do not go well.

The young people fail in their lessons at school, although they have studied hard, and really have done their best.
