Yes, cherry juice is sweet. As for your sister, do you remember Jesus saying that a prophet will not be respected by members of his own family? I'm afraid that you CAN'T do anything about Althea having CHOSEN to be evil at heart. She knows you just well enough to be able to LIE TO HERSELF that she "has you all figured out," and you have nothing to tell her. It will be up to God to find some other way of taking her down from her high-and-mighty self-delusions.
