Matthew 4:18 says,  And Jesus, walking by the sea of Galilee, saw two brethren, Simon called Peter, and Andrew his brother, casting a net into the sea: for they were fishers. When Jesus began His ministry, the first thing He did was begin to call disciples.  We might have thought that He would have gone to the priests and religious leaders to call His disciples.  Instead, Jesus called two brothers, Simon called Peter, and his brother Andrew, who were fishermen.  They were not the elite of the world, but were simply fishermen, and likely looked down on by those who were rich and powerful.  Jesus, for whatever reason, saw not what they were, but  what they would become.  However a person is viewed by the world, when that person encounters Christ, He sees not what they are, but what they can become if they answer His call to follow Him.   Verse nineteen says, And he saith unto them, Follow me, and I will make you fishers of men.  Jesus called them to follow Him and He gave them a new occupation.  They were to become fishers of men.  Since they made their living as fishermen, they were basically asked to give up everything they depended on to meet their needs and to simply put their faith in Jesus.  We are called to do the same, and to put following Jesus above all else in this world.  Verse twenty states, And they straightway left their nets, and followed him.  There was no hesitancy on the part of Simon Peter and Andrew.  They straightway, or immediately, left their nets, there source of livelihood and followed Jesus.  If we are to be effective followers of Christ, that means that following Him must come above all else.  This does not mean that when we accept Christ as our Savior and Lord that we are to immediately quit our job, but it does mean that if we feel God calling us to do something that requires quitting our job we must be willing to do so.  As followers of Christ, we must be willing to immediately follow the leadership of the Holy Spirit.  As Christians, we are all called to be fishers of men.  Verse twenty-one says, And going on from thence, he saw other two brethren, James the son of Zebedee, and John his brother, in a ship with Zebedee their father, mending their nets; and he called them.  James and John, two more brothers who were fishermen, were the next two disciples to follow Jesus.  This does not make them to be under Simon Peter and Andrew in their relationship to Jesus.  No matter when we accept Christ as our Savior and Lord, we are no higher in our standing with God than any other Christian, no matter if they have just accepted His gift of salvation.  Verse twenty-two states, And they immediately left the ship and their father, and followed him.  We are not told that Jesus called them verbally to follow Him, but they had to have felt His call.  We are not all called to Christ the same way, but we must answer His call whenever and however it comes.  James and John not only left their job, but they left their father as well.  We cannot allow anything, whether job or family, to come between Christ and us.  Verse twenty-three says, And Jesus went about all Galilee, teaching in their synagogues, and preaching the gospel of the kingdom, and healing all manner of sickness and all manner of disease among the people.  Jesus began His ministry in Galilee, teaching in synagogues, Jewish places to worship, and preaching the gospel.  Jesus also healed people of physical sickness and disease.  God will always meet our needs if we put our faith in Him.  This does not mean that all physical sickness and disease will be cured, but God does often heal people when even doctors cannot explain the person's recovery.  Whether in this life or not, God will ultimately heal all sickness.  Verse twenty-four states, And his fame went throughout all Syria: and they brought unto him all sick people that were taken with divers diseases and torments, and those which were possessed with devils, and those which were lunatick, and those that had the palsy; and he healed them. As Jesus healed people, His fame grew.  Multitudes brought people to Jesus with all kinds of illnesses, from physical to mental.  Still, Jesus did not come simply to heal physical illnesses, and we must not put the emphasis on physical healing.  Jesus came first and foremost to heal people spiritually, and that should be the focus when anyone comes to Christ.  Physical healing is temporary, whereas spiritual healing, or salvation, is everlasting.  Verse twenty-five declares, And there followed him great multitudes of people from Galilee, and from Decapolis, and from Jerusalem, and from Judaea, and from beyond Jordan.  Great multitudes followed Jesus, but I believe most followed Him for the wrong reason.  They were following Jesus to see what He would do next to meet physical needs, and not to accept Him as the Messiah, or Savior.  We must accept Jesus as our Savior and Lord, Who will meet all our spiritual needs, and not as Someone that we only want material things from.
