Between professionals and amateurs, it is obvious who will do a better job.
Professionals are paid to do the job, they are trained, they have the knowledge, the skills and the tools.
On the other hand, amateurs may have some knowledge and skills, but they do things as a hobby and not as a professional job.
In the gospel, Simon Peter and his companions were fisherman, and they make a living out of it.
But on that occasion, they worked hard all night and caught nothing.
Jesus was preaching to the crowds, and then He got into Simon Peter’s boat and continued to preach from there.
When He had finished, Jesus told Simon Peter to put out into deep water for a catch.
Peter may know that Jesus was not a fisherman, and he could have ignored what Jesus said, but for whatever reason, he decided to do as Jesus says.
That miraculous catch of fish made Peter realise that there are some things that are beyond his understanding or his expertise, and he was humbled by it.
And he also came to see that Jesus has more to reveal to him, and so he decided to follow Jesus.
As the first reading tells us, there is nothing to boast about in anything human, be it knowledge, or wisdom, or expertise, or professionalism.
When we realise how limited, or even foolish, human knowledge or wisdom can be, then let us be humble and follow the ways of God.
With humility and trust, God will show us how wonderful and fruitful it can be in following His ways.
