Epitaph in stone

Many years ago, my sister was doing research on the variation in Welsh dialects, and focussed on many stones that had a verse something like 'you who pass by, as you are, so I was, as I am, you will be, remember that you too willl die.' I don't think they were intended to be morbid, but an encouragement as you say to use life and also preparae for death by receiving Christ's grace.

My sister isn't a believer, and chose the verse as it was common on stones but varying across part of Wales because of the effect of dialect and that on rhyme etc I think! Rhiannon
