Now it happened that while Jesus was standing by the Lake of Gennesaret (Sea of Galilee), with the people crowding all around Him and listening to the word of God; that He saw two boats lying at the edge of the lake, but the fishermen had gotten out of them and were washing their nets. He got into one of the boats, which was Simon’s, and asked him to put out a little distance from the shore. And He sat down and began teaching the crowds from the boat. When He had finished speaking, He said to Simon [Peter], “Put out into the deep water and lower your nets for a catch [of fish].” Simon replied, “Master, we worked hard all night [to the point of exhaustion] and caught nothing [in our nets], but at Your word I will [do as you say and] lower the nets [again].” When they had done this, they caught a great number of fish, and their nets were [at the point of] breaking; so they signaled to their partners in the other boat to come and help them. And they came and filled both of the boats [with fish], so that they began to sink. But when Simon Peter saw this, he fell down at Jesus’ knees, saying, “Go away from me, for I am a sinful man, O Lord!” For he and all his companions were completely astounded at the catch of fish which they had taken; and so were James and John, sons of Zebedee, who were partners with Simon [Peter]. Jesus said to Simon, “Have no fear; from now on you will be catching men!” After they had brought their boats to land, they left everything and[a]followed Him [becoming His disciples, believing and trusting in Him and following His example]. – Luke 5:1-11
Peter thought of himself as an expert at fishing. Using their finest skills the night before, Peter and his partners caught nothing. Fishing Jesus’ way, which involved a violation of all of the principles of fishing Peter knew, brought great success. Following Jesus, in my estimation, means leaving behind many of the “proven methods” of our past. This statement may trouble many, but there is much truth in it, I believe. In the early chapters of the book of First Corinthians, the apostle Paul made a point to show how his methods were seemingly silly, and diametrically opposed to the methods of successful speakers of his day. But in doing things this way, in doing things God’s way, the Spirit of God produces the fruit and God receives the glory. Let us be careful about what it is we try to bring with us when we seek to follow Jesus. Not only did Peter and his partners leave behind their boats and their nets, they left their proven fishing methods behind as well. – Bob Deffinbaugh
Keep in mind that Jesus, though He is God, is living and functioning as a man during those 33 years He spent on earth. As far as we know, Jesus knew nothing about fishing. But so long as He was being led by the Spirit of God, He could speak authoritatively into situations that He had no natural knowledge about. The same is true for us. We don’t limit our sphere of ministry to those places that we are naturally familiar with and feel comfortable in. We follow wherever the Lord leads and speak whenever He gives us prompting.
