1. _Who are to believe_? 2. _When are they to believe_? 3. _How are they to believe_? I. Who are to believe? To whom does the Holy Spirit say, "Believe on the Lord Jesus Christ, and thou shalt be saved?" Now mark, I answer, _not_ to all sinners indiscriminately. And here is a grand mistake in a great deal of the teaching of this age--that these words are wrested from their explanatory connexion, and from numbers of other texts bearing on the same subject, and held up independently of all the conditions which must ever, and did ever, in the mind and practice of the Apostles, accompany them; indeed, it has only been within the last sixty or seventy years that this new gospel has sprung into existence, preaching indiscriminately to unawakened, unconverted, unrepentant sinners--"Believe on the Lord Jesus Christ." It seems to me, that great injury has been done to the cause of Christ by thus wrongly dividing the Word of truth, to say nothing of the unphilosophical character of such a course, for how can an unawakened, unconvicted, unrepentant sinner, believe? As soon might Satan believe. It is an utter impossibility. Thousands of these people say, "I do believe." My dear son, only a little time ago, on the top of an omnibus, was speaking to a man who was the worse for liquor, and using very improper language; trying to show him the danger of his evil, wicked course, as a transgressor of the law of God. "Oh!" said the man, "it is not by works, it is by faith, and I believe as much as you do." "Yes," said my son, "but what do you believe?" "Oh," he said, "I believe in Jesus Christ, and of course I shall be saved." That is a sample of thousands. I am meeting with them daily. They believe there was such a man as Jesus, and that He died for sinners, and for them, but as to the exercise of saving faith, they know no more about it than Agrippa or Felix, as is manifest when they come to die, for then, these very people are wringing their hands, tearing their hair, and sending for Christians to come and pray with them. If they had believed, why all this alarm and concern on the approach of death? They were only believers of the head, and not of the heart; that is, they were but theoretical believers in the facts recorded in this book, but not believers in the Scriptural sense, or their faith would have saved them. Now, we maintain that it is useless, and as unphilosophical as it is unscriptural, to preach "only believe" to such characters; and Christians have not done their duty, and have not discharged their responsibility to these souls, when they have told them that Jesus died for them, and that they are to believe in Him! They have a much harder work to do, and that is, "to open their eyes" to a sense of their danger, and make them, by the power of the Spirit, realize the dreadful truth that they are sinners, that they are sick, and then they will run to the Physician.
