Two aspects of the return of Jesus are really beyond question. His advent will involve the personal presence of one now absent, the visible presence of one now unseen.  Beyond this we shall be wise to exercise caution. The actual manner of his personal, visible return will no doubt transcend both the categories in which the prophecy has been made and the measure of our own understanding. It will be a dramatic, cataclysmic event terminating the whole process of history. But, although we may not wish to dogmatize beyond this point, we cannot stop short of it if we would be true to the New Testament revelation. The return of Jesus may indeed be more glorious, but it cannot be less than fully personal and visible.
