Recently, while posting messages to the "Super User" and "Server Fault" Stack Exchange sites, the moderators summarily edited out the phrases "Thank you ( see Colossians 3:15, for example )" and "Sincerely in Christ," which were included in my posts. Will that happen here?
All manner of "thank you" and "sincerely"s are edited away all throughout the Stack Exchange network as they are not seen as necessary or useful here.
But if you'd like to encourage people to read a particular Bible verse or two, you could put it in your profile description (the "about me" box.)
In addition to what curiousdannii answered which is spot on as far as tag lines of all sorts being generally rejected in SE sites across the board, it also bears noting specifically that this is not a forum. I see you've used that word in some removed tag-lines (including from the above question in reference to this site). SE sites are not forums, they are not for discussion or social back and forth. As such the feature set and site "norms" specifically avoid anything that encourages or feels like that sort of interaction. The sites are question and answer sites, and each post is question with direct answers, not a forum with discussion threads.
Thoroughly groking this difference will make it a lot easier to use the site appropriately. Anything that doesn't make questions clearer or answers more direct probably doesn't belong. You can use your profile to say a bit about yourself or even forward an agenda, but if your purpose in writing posts is to get people to visit your personal sites or read a verse or change their minds about some issue then this is probably not the site for you.
