The Believer's Responsibility

Leaving the sad case of mere professors, let us ask to what extent we represent the view here presented of the believer's responsibility. How many true Christians think: "I am here for Christ, in charge of His interest in the scene where He has been rejected"? How would the world appear to one who had this thought about the place he was called upon to occupy?
The cross as the means by which sins were put away is, of course, valued by all real believers. In this sense they can, and do glory in it.
But Paul gloried in it for another reason and saw in the death of Christ another aspect. To him, that death was not only deliverance from sins, but deliverance "from this present evil world." To him that cross was not only the place where sin had been judged, but the means by which "the world is crucified unto me, and I unto the world." He saw in the death of Christ the death of all. "And that He died for all, that they which live should not henceforth live unto themselves, but unto Him which died for them, and rose again." 2 Cor. 5:15. What complete separation from the world and what devotedness to Christ we see here.
