Luke 5:4
When he had finished speaking, he said to Simon, "Now go out where it is deeper and let down your nets to catch some fish." "master," Simon replied, "we worked hard all last night and didn't catch a thing. But if you say so, I'll let the nets down again." And this time their nets were so full of fish they began to tear!... When Simon Peter realized what had happened, he fell to his knees before Jesus and said, "Oh, Lord, please leave me---I'm too much of a sinner to be around you." For he was awestruck by the number of fish they had caught, as were the others with him... Jesus replied to Simon, "Don't be afraid! From now on you'll be fishing for people!" And as soon as they landed, they left everything and followed Jesus.
Past - Your future is not determined by your past
Problems - Our biggest problem is not taking our problems to the Problem Solver - Jesus!
Preference - Some of us will only serve God to the extent of our comfort.
Performance - We do not feel good enough because of how we have performed in the past. God loves us too much to keep us where we are at. He want us to go further.
