We don't know much about St Joseph. But what we do know is pretty much all we need to know. St Joseph was a just man, a righteous man. He was humble, hard working, and the man chosen to be a father figure to the Lord Jesus, and spouse to the Blessed Virgin Mary.
For my confirmation, I get to choose a Saint who inspires me, a role model whose values and virtues I can try to live by. There are many wonderful Saints, but over time I have become close to St Joseph. I am a Dad, to two wonderful children, in difficult circumstances. A remnant of the way my life used to be, a painful reminder of the mistakes I made. I draw inspiration from St Joseph, as a Father, and if I could be just a tenth of the man St Joseph is, I would be fortunate indeed.
