When should a minister share about their past?

I’ve had an abortion.
I’ve been sexually assaulted.
I’m married to someone who has mental health challenges.
I’ve been addicted to porn.
My wife and I have endured multiple miscarriages.
I used to be an alcoholic.
One of my children died of SIDS.

Any minister who has gone through any of the above things, and a number of other examples, would be a powerful witness and advocate for those they minister to.

Except... these are the types of things we keep private.

So, when should a minister disclose things from their past which could be powerfully used? Additionally, how should they do so?

I ask because at least one of the things listed above are a part of my past. And, they have been helpful in helping others. I got through them. I can empathise with with someone going through them.

Should a minister bring their past to the surface fairly early on in their ministry placement, in a public setting, so others will be aware and can come forward if they want?

Or, does a minister keep their past close to their chest, only revealing once someone has an event which they can then disclose their connection with?

I don’t know the answer, but disclosure of some of a minister’s skeletons would help remove the ministerial veneer and open up new avenues of ministry.
