“[a St. Luke 14:26.] Of course, the term 'hate' does not imply hatred of parents or relatives, or of life, in the ordinary sense. But it points to this, that, as outward separation, consequent upon men's antagonism to Christ, was before them in the near future, so, in the present, inward separation, a renunciation in mind and heart, preparatory to that outwardly, was absolutely necessary. And this immediate call was illustrated in twofold manner. A man who was about to begin building a tower, must count the cost of his undertaking. [b vv. 28-30.] It was not enough that he was prepared to defray the expense of the foundations; he must look to the cost of the whole. So must they, in becoming disciples, look not on what was involved in the present following of Christ, but remember the cost of the final acknowledgement of Jesus. Again, if a king went to war, common prudence would lead him to consider whether his forces were equal to the great contest before him; else it were far better to withdraw in time, even though it involved humiliation, from what, in view of his weakness, would end in miserable defeat. [c vv. 31, 32.] So, and much more, must the intending disciple make complete inward surrender of all, deliberately counting the cost, and, in view of the coming trial, ask himself whether he had, indeed, sufficient inward strength, the force of love to Christ, to conquer. And thus discipleship, then, and, in measure, to all time, involves the necessity of complete inward surrender of everything for the love of Christ, so that if, and when, the time of outward trial comes, we may be prepared to conquer in the fight. [d ver. 33.] He fights well, who has first fought and conquered within.”
