There was a third case. Another man, overhearing what had been said, proposed also to become a disciple--but not yet. "I will follow thee; but first suffer me to bid farewell to them that are at my house." That, too, appeared only a fit thing to do; but again the answer seems stern and severe. "No man, having put his hand to the plough, and looking back, is fit for the kingdom of God." Even the privilege of running home to say "Good-by" must be denied to him who follows Jesus.
These incidents show, not that Jesus would make it hard and costly for men to be his disciples, but that discipleship must be unconditional, whatever the cost, and that even the holiest duties of human love must be made secondary to the work of Christ's kingdom. Another marked instance of like teaching was in the case of the young ruler who wanted to know the way of life. We try to make it easy for inquirers to begin to follow Christ, but Jesus set a hard task for this rich young man. He must give up all his wealth, and come empty-handed with the new Master. Why did he so discourage this earnest seeker? He saw into his heart, and perceived that he could not be a true disciple unless he first won a victory over himself. The issue was his money or Jesus--which? The way was made so hard that for that day, at least, the young man turned away, clutching his money, leaving Jesus.
Really, a like test was made in every discipleship. Those who followed him left all, and went empty-handed with him. They were required to give up father and mother, and wife and children, and lands, and to take up their cross and follow him.
Why were the broad invitations of the heart of Jesus so narrowed in their practical application? The answer is very simple. Jesus was the revealing of God--God manifest in the flesh. He had come into this world not merely to heal a few sick people, to bring back joy to a few darkened homes by the restoring of their dead, to formulate a system of moral and ethical teachings, to start a wave of kindliness and a ministry of mercy and love; he had come to save a lost world, to lift men up out of sinfulness into holiness.
There was only one way to do this,--men must be brought back into loyalty to God. Jesus astonishes us by the tremendous claims and demands he makes. He says that men must come unto him if they would find rest; that they must believe on him if they would have everlasting life; that they must love him more than any human friend; that they must obey him with absolute, unquestioning obedience; that they must follow him as the supreme and only guide of their life, committing all their present and eternal interests into his hands. In a word, he puts himself deliberately into the place of God, demanding for himself all that God demands, and then promising to those who accept him all the blessings that God promises to his children.
This was the way Jesus sought to save men. As the human revealing of God, coming down close to humanity, and thus bringing God within their reach, he said, "Believe on me, love me, trust me, and follow me, and I will lift you up to eternal blessedness." While the invitation was universal, the blessings it offered could be given only to those who would truly receive Christ as the Son of God. If Jesus seemed to demand hard things of those who would follow him, it was because in no other way could men be saved. No slight and easy bond would bind them to him, and only by their attachment to him could they be led into the kingdom of God. If he sometimes seemed to discourage discipleship, it was that no one might be deceived as to the meaning of the new life to which Jesus was inviting men. He would have no followers who did not first count the cost, and know whether they were ready to go with him. Men could be lifted up into a heavenly life only by a friendship with Jesus which would prove stronger than all other ties.
