In today's Gospel reading from Luke 5, before Jesus taught his disciples to catch men, he showed them how to catch fish. Jesus told Peter to put the boat out into deep water and pay out the nets for a catch. Peter and his companions had worked hard all night long and caught nothing, but they obeyed. They netted an unbelievably huge number of fish and were completely overwhelmed by the catch. Peter fell at the knees of Jesus saying, "Leave me, Lord; I am a sinful man."
This is how the Lord teaches and draws us ~ he lets us have a personal experience and we are overwhelmed. Then we know that he is Lord and we are won over. As Peter showed, the winning-over itself is a sweet experience.
