Discerning a vocation is a big deal and one that should be taken seriously by young people. That isn't always (or even frequently?) the case, however. For the past year or so, when we say the rosary at night, I pray with my big boys that they choose the right vocation in life and be the people God wants them to be. I don't know what God has in mind for my children. I know where their strengths and weaknesses lie, but what they are supposed to do with them is still a mystery to me and to them. Neither one of them has an interest in becoming a priest, but they don't show much interest in marriage either. Of course, puberty may change that! Whatever they do or become, I want them to be the men God created them to be.
On the other hand, the young man who wrote the following blog post: Vocation Discernment may very well have a vocation to the priesthood. I know him and in my humble estimation, he has the intelligence and personality to make a good one, if that is what God is calling him to do. And that's the thing - he's really working to figure that out - whether God is calling. Maybe you could say a prayer for him as he works through this process?
I wish all young people, my own children included, would take discerning who and what they are supposed to be in life as seriously.
