Rev Wilson's weight couldn't be supported by a single balloon but when he used a table to rest on all of our balloons, not only did they support his weight - he invited us all to join him on the table and bounce - and we survived to tell the tale!
Jesus called His disciples to be "fishers of men". It might be argued that Jesus wasn't the best judge of character, given the sort of people He chose. But He knew what He was doing.
They were ordinary people just like you and me. Crucially, the sort of individuals who could related to all sorts of different people - and bring them "on board" too. Ordinary people to do extraordinary things.
Rev Wilson went on to indicate that that's where each of us comes in. The work of the church, the extension of God's kingdom, the fishing for men is too much of one person to carry the load.
Jesus doesn't ask about our backgrounds, or education, our beliefs, or anything else about us. He welcomes us just as He did the disciples. He knew that Peter, Simon, Judas and Thomas would let Him down.
He knows that we will find it difficult, at times, to be strong, and to overcome our fear at others, but encourages us, as He did them:
“Don’t be afraid; from now on you will fish for people.” So they pulled their boats up on shore, left everything and followed him. Luke 5:10, 11
