My former desire to give myself to missionary service returned, and I went at last to my father to obtain his permission, without which I could not be received into any of the German missionary institutions. My father was greatly displeased, and particularly reproached me, saying that he had expended so much money on my education, in hope that he might comfortably spend his last days with me in a parsonage, and that he now saw all these prospects come to nothing. He was angry, and told me he would no longer consider me as his son. But the Lord gave me grace to remain steadfast. He then entreated me, and wept before me; yet even this by far harder trial the Lord enabled me to bear. After I had left my father, though I wanted more money than at any previous period of my life, as I had to remain two years longer in the university, I determined never to take any more from him; for it seemed to me wrong, so far as I remember, to suffer myself to be supported by him, when he had no prospect that I should become what he would wish me to be, namely, a clergyman with a good living. This resolution I was enabled to keep.
Shortly after this had occurred, several American gentlemen, three of whom were professors in American colleges, came to Halle for literary purposes, and, as they did not understand German, I was recommended by Dr. Tholuck to teach them. These gentlemen, some of whom were believers, paid so handsomely for the instruction which I gave them, and for the lectures of certain professors which I wrote out for them, that I had enough and to spare. Thus did the Lord richly make up to me the little which I had relinquished for his sake. "_O fear the Lord, ye his saints; for there is no want to them that fear him._"
Whitsuntide, and the two days following, I spent in the house of a pious clergyman in the country; for all the ministers at Halle, a town of more than twenty thousand inhabitants, were unenlightened men. God greatly refreshed me through this visit. Dear Beta was with me. On our return we related to two of our former friends, whose society we had not quite given up, though we did not any longer live with them in sin, how happy we had been on our visit. I then told them how I wished they were as happy as ourselves. They answered, We do not feel that we are sinners. After this I fell on my knees, and asked God to show them that they were sinners. Having done so, I went into my bedroom, where I continued to pray for them. After a little while, I returned to my sitting-room and found them both in tears, and both told me that they now felt themselves to be sinners. From that time a work of grace commenced in their hearts.
Though very weak and ignorant, yet I had now, by the grace of God, some desire to benefit others, and he who so faithfully had once served Satan, sought now to win souls for Christ. I circulated every month about three hundred missionary papers. I also distributed a considerable number of tracts, and often took my pockets full in my walks, and distributed them, and spoke to poor people whom I met. I also wrote letters to some of my former companions in sin. I visited, for thirteen weeks, a sick man, who, when I first began to speak to him about the things of God, was completely ignorant of his state as a sinner, trusting for salvation in his upright and moral life. After some weeks, however, the Lord allowed me to see a decided change in him, and he afterwards repeatedly expressed his gratitude that I had been sent to him by God to be the means of opening his blind eyes.
Having heard that there was a schoolmaster living in a village about six miles from Halle, who was in the habit of holding a prayer meeting at four o'clock every morning, with the miners, before they went into the pit, giving them also an address, I thought he was a believer; and as I knew so very few brethren, I went to see him, in order, if it might be, to strengthen his hands. About two years afterwards, he told me that when I came to him first he knew not the Lord, but that he had held these prayer meetings merely out of kindness to a relative, whose office it was, but who had gone on a journey; and that those addresses which he had read were not his own, but copied out of a book. He also told me that he was much impressed with my kindness, and what he considered condescension on my part in coming to see him, and this, together with my conversation, had been instrumental in leading him to care about the things of God, and I knew him ever afterwards as a true brother.
