can you translate the following for me? it is apparently from an old tombstone and according to my friend, the language has changed enough that online translators do not work.....
the following is the facebook post of the words:

'du warst so gut so bieder voll glauben allezeit; drum schau'ich einst dich wieder in himmels sel'ger freud ---- I think it might be part of a Robert Burns poem. His name keeps coming up.'


much thanx for any help you can be!
