I'm looking for a Manga/Manwha I started reading a while ago, but forgot the name of.

It was a reincarnation story, but there was a plot point that children born in the new timeline that hadn't existed in the original would reflect holy blessings. First time it happened, the priest looked freaked out, but pretended everything was fine. I think the first such child was a result of curing some old soldier's war wound that had left him impotent.
