Remember this well-known exchange from John 21? 
  
"Jesus said to Simon Peter, "Simon, son of John, do you love 
Me more than these?" He said to Him, "Yes, Lord; You know that I love 
You." He said to him, "Tend My lambs."
 
          
          He said to him again a second 
time, "Simon, son of John, do you love Me?" He said to Him, "Yes, Lord; 
You know that I love You." He said to him, "Shepherd My sheep."
 
          
          He said to him the third time,
 "Simon, son of John, do you love Me?" Peter was grieved because He said
 to him the third time, "Do you love Me?" And he said to Him, "Lord, You
 know all things; You know that I love You." Jesus said to him, "Tend My
 sheep." 
When Jesus said 
love, he used the Greek word 
agape, meaning selfless, sacrificial, unconditional love.  When Peter said 
love, he used the Greek word 
phileo, meaning benevolent, kindly love that is found in friendship.
Peter may have started as a 
phileo lover of Jesus, but he eventually became an
 agape lover of Jesus.  Tradition tells us that he was crucified upside down as a martyr for Jesus Christ.
Likewise, one may start out as a 
phileo and 
eros (physical) lover of one's spouse, but can grow to be an 
agape lover.  Christ brings about that change as we stay in close communion with Him.  He did it for Peter.  He can do it for us.
