Probably Paul's opposition to Christianity was from the first very specially opposition to Christ Himself. When he struck at the disciples, he was really striking at the Master through them. It is easy to conceive what an affront the pretensions of Jesus must have been felt to be by Paul. Jesus had been a man of about his own age--a young man; he had sprung from the lowest of the people, being a villager and mechanic; he had never sat in the schools of learning; the men of ability and authority had had no hesitation in condemning Him. That such a one should be esteemed the Messiah of the Jews and worshipped as if He were Divine, raised a storm of indignation in the heart of Paul.
Probably nothing could have converted him except the miraculous occurrence which God employed. Christ had to come to him in person and in a visible shape--in the shape of the glorified humanity which He wears somewhere in that empire of God which we call Heaven. Paul knew the light in which he was enveloped to be a Divine light; the sound of the voice calling him was the thunder which from of old had been recognised by the race to which he belonged as the voice of God; he was looking straight up to the place of God; and in that place he saw Jesus, whom he was persecuting. Most Divine of all, however, were the sweetness, the clemency and the respect of the words in which he was addressed. This Jesus, against whom he was raging, came to him, not with corresponding rage, to take vengeance and destroy him, but with winning words of truth and with the call to a high and blessed vocation. It was this which broke the heart of Paul and attached him to Christ forever.
He always afterwards believed that what took place on this occasion was what I have said--that Jesus of Nazareth descended from the right hand of God to prove to him who He was and to claim him as His servant and apostle--and never afterwards did he for a moment doubt that the man whom his fellow-countrymen had crucified, and whom he himself had persecuted, was seated on the throne of heaven, clothed with Divine blessedness and omnipotence.
Of course others have doubted this. It may be said that what Paul saw was only a vision, and that therefore his new life was founded on a mistake. I believe his own account to be the correct one; but perhaps we need not dogmatize too much about what he saw; because it was not in reality on any theory of this vision that his faith was founded. It was not because he saw Christ that day with the bodily eye, or believed he did so, that he became or continued a Christian; it was because, trusting Christ, thus revealed, he obtained that for which he had all his life been longing: he was no longer banished or kept at a distance, but brought nigh to God; he was reconciled, and the love of God was shed abroad in his heart. He had all his lifetime been asking in despair, "What must I do to be saved?" but now he was saved. The humiliating bondage in which his spiritual nature had been held was dissolved, and, following Christ, he advanced from victory to victory.
This is the test of all conversions; it is the best evidence of Christianity; and it is the power of preaching. We believe in Christ not only because there is sufficient historical evidence that He existed eighteen hundred years ago and did such acts as proved that He was sent from God, but because He proves Himself to be living now by the transformation which He brings to pass in those who put their trust in Him. We are certain that there is a Saviour, because He has saved ourselves. I am happy to see that this evidence of our religion is at present coming again to the front. One of your younger scholars, Dr. Stearns of Bangor, Maine, has developed it, in a book just published, with great breadth of theological knowledge; and a former Yale lecturer, Dr. Dale of Birmingham, has given a telling exposition of it at the same time.[49] This is the vital force of preaching. We are witnesses to Christ--not merely to a Christ who lived long ago and did wonders, but to a Christ who is alive now and is still doing moral miracles. And the virtue of any man's testimony lies in his being able to say that he has himself seen the Christ whom he preaches to others, and himself experienced the power which he recommends others to seek.
