it's a complicated answer: faith is at the heart of it, of course. In Christianity there's the idea of vocation, which applies to all, not just the clergy. A simple way to think about it is to consider the things you're good at, the things you can do that will serve others, and what you enjoy: imagine that as a Venn diagram, and try to discern what lies in the middle for you.

My software skills still play a part in what I do. But seven or eight years ago now I felt drawn to explore a vocation in ordained ministry – after study, a formation programme, completing a Masters degree in Divinity, and a lot of thought and prayer, here I am. It's the happiest I've ever been. Which isn't to say that it hasn't been difficult: being a cleric is not easy work.

Intentional discernment about vocation really has made my life a lot happier, and it's something I talk about a little because it's of value to other people as well.

(I'm in the Anglican [in the states, Episcopalian] tradition, but the process of ministerial formation is very broadly similar between the various mainline protestant denominations and Roman Catholicism.)

Software engineer turned priest, perfect story for HN on Christmas Day, do tell!

Yes, don't leave us hanging (on Christmas, no less!).
