There are many stories of people who changed their professions somewhere along in life.
And the change to a new profession is a totally different and unrelated to the previous profession.
Some changed from a white-collar job to a blue-collar job. Some changed from engineering to the arts. Some changed from management posts to being hawkers.
Some of these stories are amusing and even inspiring.
But for St. Matthew, the change from being a tax-collector to a disciple of Jesus was quite astonishing.
Yes, St. Matthew responded to the call of Jesus, but he had to make that difficult decision to walk away from a comfortable income, although it comes with an un-respectable and despicable reputation.
To make the change was not possible until Jesus came along.
So change for the better is possible only when Jesus is calling and it is also in God's time.
Let us, like St. Matthew, be prepared to listen to the voice of Jesus.
When He calls, let us also be willing to respond.
