Augustine of Hippo

(Tr. xlv. 15) But He Himself explains it more satisfactorily to me in what follows: The thief cometh not, but for to steal, and for to kill: I am come that they might have life, and that they might have it more abundantly. By going in they have life; i. e. by faith, which worketh by love; by which faith they go into the fold. The just liveth1 by faith. And by going out they will have it more abundantly: (Heb. 10:38) i. e. when true believers die, they have life more abundantly, even a life which never ends. Though in this fold there is not wanting pasture, then they will find pasture, such as will satisfy them. To-day shalt thou be with Me in paradise. (Luke 23:43)
