Service is also one of the surest preventives from wandering. It is when the brain is idle that evil thoughts master it; when the heart is given up to impure imaginations that we find it easy to fall. And it is when we are busy lifting others' burdens; making the way easier for others to travel; comforting those who are in distress; speaking a word of cheer to the cheerless, and above all, when we are seeking to lead others to Christ, that we ourselves grow in grace and in the knowledge of our Lord and Saviour Jesus Christ. If these things are true, and we know they are, then it is the duty of every Christian not only to seek to win another to Christ, but by all means to seek to hold him when once he is won, and that which we know holds us will keep others from stumbling. The suggestions made above are for the young as well as the more mature. Young people will be interested in spiritual things if we have sufficient interest in them ourselves to make them attractive. If we would show as great interest in helping to keep those whom we may have won for Christ, as we revealed when we were seeking them, fewer of them would drift. CHAPTER VIII _A Practical Illustration_ It will be a great day when the Church is aroused to the responsibility and privilege of personal work. In Swansea, Wales, with Mr Charles M. Alexander, I had the satisfaction of conducting a mission in which I preached for an entire week on Soul Winning. I then urged the people to go forth and labour, and asked them to come back with their reports. These reports were thrilling. Often ten or twelve people would be standing at the one time waiting to speak. The following are only a few testimonies taken from the many:-- A minister said: "I spoke to a bright young fellow, under the influence of drink, as I was going home in the car last night. He got off the car when I did, so I stood at the street corner and talked with him for a few minutes. He told me that he had been a follower of the Lord Jesus many years ago, but had fallen away through bad company. I asked him to pray for himself. He said he could not, but asked me to pray for him. And there on that street corner I put my arm around his shoulder and we prayed together, and he has promised to come to the meeting to-night." "About three years ago," said another, "I came in touch with a man who has been the biggest and most hardened scoffer I have had to contend with. He had such a sarcastic way of ridiculing the Lord Jesus Christ. But this last fortnight I have seen a distinct change in that young man's life. Last week, as we were working near to one another, I spoke to him and his eyes filled with tears. He said, 'I have decided to come out and accept Christ.' I could hardly credit it, but it has proved to be real, and when I see God moving in such a hard case as this, I have hope for every sinner in this city."
