In John 6, Jesus has fed thousands of people with a sack lunch and then walked on water during the night to head to Capernaum. The next day some people show up on the side of the lake where Jesus had been and realize that He is not there. Scripture tells us that they then got back in their boats and went to the other side of the lake to look for Jesus and the disciples.
The persistence of these people in searching for Jesus is significant. They had heard about Him, the miracles He was performing and the truth He was teaching and were desperate to experience it. When they arrived where they thought He was and found that He was gone they didn't give up. They continued to search in the next place in hopes of finding Him.
I admire their tenacity and willingness to make an effort to find Christ. It is an example for us to do the same today. We can't simply show up on a Sunday/Wednesday and then walk away disappointed that it wasn't a mountain-top experience. I think we too often sit back with an attitude of "show me Jesus" and then criticize when it doesn't happen. The responsibility lies with each of us to search for Him with fervor and passion and to be committed to searching with all our hearts to find Him.
Maybe we don't seek for Him with all our hearts because unlike the crowd in Scripture, we don't really want to find Him.
