It all started when Jesus asked Peter if he could borrow his boat. Jesus told him to push the boat a short way out from the shore to give him a safe place to speak.
Then Jesus told him to push out into the deep water. What happened next would change Peter's life forever.
A few years later Peter would stand before a huge crowd and announce the resurrection of Jesus. Thousands of people believed. Peter had become a 'fisher of people'* just as Jesus said he would.
Jesus sometimes asks us to do things that seem small. My advice is that you do them. You never know when Jesus will want to do something big. You never know how Jesus wants to teach you or shape you. A little obedience can lead to big things.
Practice doing small acts of obedience today: hoover the carpet, pick up some litter, lay out the chairs. You never know where it will lead. Peter didn't start by preaching to thousands; he started by letting Jesus borrow his boat, and pushing it a short way out from the shore. It was this small act of obedience that led to the encounter that changed his life.
* or 'fisher of men' but the Greek word isn't gender specific
