How many times did the door shut? (P3, Pg. 213)

On the other hand, the closing of the "door," in the parable of Matt. xxv., marks the full end of all opportunity for any, even of the "called" ones, thereafter to attain the prize of the high calling. It marks the end of all opportunity to prove worthy of the prize by faithfulness in the service: all opportunity for service will there terminate, in the "night" wherein no man can work ( John 9: 4). It is manifest, therefore, that the door, or opportunity, thus to make our calling and election sure, does not necessarily close when the call, or general invitation to all believers to enter, ceases to go forth. And, while the door stands open, it indicates that any believer who is anxious to enter and ready to comply with the conditions may yet do so, even though the general "call" or invitation to enter is no longer sent out. As a matter of fact, the door or opportunity to labor and sacrifice has not yet closed, though the general call ceased in 1881.
