In a small group study of the apostle Peter, we brainstormed whatever words and phrases came to mind when thinking of Peter, and the first one that came up for multiple people was “impulsive.”  We covered one example of Peter’s impulsiveness in the second part of the study, which comes from the use of the word “immediately” near the end of Matthew 4:18-20:

“While walking by the Sea of Galilee, [Jesus] saw two brothers, Simon (who is called Peter) and Andrew his brother, casting a net into the sea, for they were fishermen.  And he said to them, “Follow me, and I will make you fishers of men.”  Immediately they left their nets and followed him.”

Taken on their own, these verses make it look like Peter dropped everything “immediately” the first time he met Jesus.  Very impulsive!  However, there is some important background found earlier in John 1:35-41:

“The next day again John was standing with two of his disciples, and he looked at Jesus as he walked by and said, “Behold, the Lamb of God!”  The two disciples heard him say this, and they followed Jesus.  Jesus turned and saw them following and said to them, “What are you seeking?” And they said to him, “Rabbi” (which means Teacher), “where are you staying?”  He said to them, “Come and you will see.” So they came and saw where he was staying, and they stayed with him that day, for it was about the tenth hour.  One of the two who heard John speak and followed Jesus was Andrew, Simon Peter’s brother.  He first found his own brother Simon and said to him, “We have found the Messiah” (which means Christ).”

From this we know that Andrew was Peter’s brother, and that Andrew was a disciple of John the Baptist.  Andrew began to follow Jesus, partly based on John’s testimony then, believing that Jesus was the Messiah, testified to his brother Simon, who is soon re-named, in John 1:42 –

“[Andrew] brought [Peter] to Jesus. Jesus looked at him and said, “You are Simon the son of John? You shall be called Cephas” (which means Peter).”

Another bit of important context is the verse leading up to Peter’s call in Matthew, chapter 4, verse 17: “From that time Jesus began to preach, saying, ‘Repent, for the kingdom of heaven is at hand.’”  Mark also prefaces the story of Peter’s call by Jesus with a call to repentance (Mark 1:15).  Both gospel writers are implying that Peter’s response to Jesus is an example of repentance for us to learn from.

But what is repentance and how does Peter’s call illustrate it?  The word repent means to think differently about something.  I’ve heard repentance defined as “a U-turn on the road of life” which includes both a turning away from sin, and a turning toward God in thankful obedience.  Peter, in following Jesus, was thinking differently about the best way to live his life.  He turned to Jesus as the best answer to his life’s meaning and purpose.

This decision is not one to be taken lightly, and while Peter followed “immediately,” he was not as impulsive as we might think.

“For which of you, desiring to build a tower, does not first sit down and count the cost, whether he has enough to complete it?” – Luke 14:28
