Personally, I find it better to give over discussing tricky details of theology unless one finds a conversational partner willing to engage quite deeply, in a forum that suits such discussion. FaceBook, thou art not it.
Indeed, it is an eternal temptation to substitute Pharisaical arrogance in one’s doctrinal understanding for the humility of one loved by God, not for any works which she has done (for God loved her before she possessed any works at all; such works are a sign of her love, not the causes of His). I’m also fairly sure that anyone discussing Calvinism self-selects for enjoyment of controversy. 😉
H/t to my mother on FaceBook 🙂
