Huldah and Anna!
Two old woman Prophetesses are mentioned in the Bible in relation to warns a king that the people were not with him in relation to worshipping God, they were only giving lip service, a warning today to the many so called Church goers?
Anna on the other hand lived most of her life in the Temple area in Jerusalem and was granted those extra years to see the birth of the Messiah into human flesh!
God does not give up on age, in fact older people have more experience of life, we are not always good as yet with the tech, but the next generation will be better?
2 Kings 22:14-20, 1 Chronicles 34:22-28, Luke 2:36-37.
