Simon and Andrew have no idea what was about to happen to them,… in this text where we are first introduced to them, they are merely fisherman going about their routine duties of mending nets and catching fish. How glorious is the change that Jesus can bring to a human life! And change is His purpose. Jesus tells Simon and Andrew that He is going to make them something that they currently are not. At the moment they fish for fish. Jesus is going to make them fishers of men.
