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." 5 "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." 6 And this time their nets were so full of fish they began to tear! 7 A shout for help brought their partners in the other boat, and soon both boats were filled with fish and on the verge of sinking. 8 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." 9 For he was awestruck by the number of fish they had caught, as were the others with him.

Commentary on Luke 5:1-11
(Read Luke 5:1-11)
When Christ had done preaching, he told Peter to apply to the business of his calling. Time spent on week days in public exercises of religion, need be but little hinderance in time, and may be great furtherance to us in temper of mind, as to our worldly business. With what cheerfulness may we go about the duties of our calling, when we have been with God, and thus have our worldly employments sanctified to us by the word and prayer! Though they had taken nothing, yet Christ told them to let down their nets again. We must not abruptly quit our callings because we have not the success in them we desire. We are likely to speed well, when we follow the guidance of Christ's word. The draught of fishes was by a miracle. We must all, like Peter, own ourselves to be sinful men, therefore Jesus Christ might justly depart from us. But we must beseech him that he would not depart; for woe unto us if the Saviour depart from sinners! Rather let us entreat him to come and dwell in our hearts by faith, that he may transform and cleanse them. These fishermen forsook all, and followed Jesus, when their calling prospered. When riches increase, and we are tempted to set our hearts upon them, then to quit them for Christ is thankworthy.
