I'm a little bit behind in keeping up to date with our Sunday mornings, so here's the beginnings of an attempt to catch up.
At the end of John 6 Jesus has been saying things that many of his followers are finding difficult - not necessarily difficult to understand, but difficult to put into practice or accept. As a result many of them leave and no longer follow Jesus.
Jesus is offering them life - but they want to settle for something a little easier.
How do we respond when we are challenged by Jesus' teaching? Do we take the bits we like and ignore some of the harder challenges that require sacrifice?
Jim Elliot was killed, aged just 28, in 1956 as he was seeking to take the gospel into the jungles of South America.
One of his most well known quotes is, 'He is no fool who gives what he cannot keep to gain that which he cannot lose'.
Those followers of Jesus who walked away that day took the easier option but they gave up the promise of eternal life.
Peter knew that only Jesus had the words of eternal life and therefore he was prepared to follow Jesus whatever the cost - although he still continued to make mistakes along the way.
When the going gets tough - what do we do?
