Good morning @actsinmotion,
If you look at the lower portion of each message, it lists all of the tags. See the lower portion of the above message? There are five tags listed, one is "christian-trail."
Here is an article that explains what Steemit witness's do. It's older but very informative.
idnit is the Christian-Trail's own member, and would make an outstanding witness. I hope that everyone is able to take the time to vote.
Here's a link to where anyone can vote for a witness:

Just scroll down on the page, to make your vote.
