But probably the main reason for the exceptional commandment to go and publish abroad what the Lord had done was to be found in the simple fact that this man's malady and his disposition were such that external work of some sort was the best thing to prevent him from relapsing into his former condition. His declaration to everybody of his cure would help to confirm his cure; and whilst he was speaking about being healed, he would more and more realise to himself that he was healed. Having work to do would take him out of himself, which no doubt was a great security against the recurrence of the evil from which he had been delivered. But however that may be, look at the plain lesson that lies here. Every healed man should be a witness to his Healer; and there is no better way of witnessing than by our lives, by the elevation manifested in our aims, by our aversion from all low, earthly, gross things, by the conspicuous--not made conspicuous by us, conspicuous because it cannot be hid--concentration and devotion, and unselfishness and Christlikeness of our daily lives to show that we are really healed. If we manifest these things in our conduct, then, when we say 'it was Jesus Christ that healed me,' people will be apt to believe us. But if this man had gone away into the mountains and amongst the tombs as he used to do, and had continued all the former characteristics of his devil-ridden life, who would have believed him when he talked about being healed? And who ought to believe you when you say, 'Christ is my Saviour,' if your lives are, to all outward seeming, exactly what they were before? The sphere in which the healed man's witness was to be borne tested the reality of his healing. 'Go home to thy friends, and tell _them_.' I wonder how many Christian professors there are who would be least easily believed by those who live in the same house with them, if they said that Jesus had cast their devils out of them. It is a great mistake to take recent converts, especially if they have been very profligate beforehand, and to hawk them about the country as trophies of God's converting power. Let them stop at home, and bethink themselves, and get sober and confirmed, and let their changed lives prove the reality of Christ's healing power. They can speak to some purpose after that. Further, remember that there is no better way for keeping out devils than working for Jesus Christ. Many a man finds that the true cure--say, for instance, of doubts that buzz about him and disturb him, is to go away and talk to some one about his Saviour. Work for Jesus amongst people that do not know Him is a wonderful sieve for sifting out the fundamental articles of the Christian faith. And when we go to other people, and tell them of that Lord, and see how the message is sometimes received, and what it sometimes does, we come away with confirmed faith.
