"Sirs, what must I do to be saved?"--Acts xvi. 30. I do not know of any more important truth to bring out than the answer to this question, because that is the beginning of everything with regard to the divine life. A man must know he is saved before there is any peace, or joy, or comfort. The answer to the question is, "Believe on the Lord Jesus Christ, and thou shalt be saved"; and the question that comes right after that from almost every one is, "What is it to believe?" I believe that Jesus Christ is the Son of God; I believe that He came into the world to save sinners. Well, and so do the devils. The devils not only believe, but they tremble. I can believe intellectually that Jesus Christ is able and willing to save, and yet be as far from the kingdom of God as any man who never heard about Jesus Christ. To believe that He can and is willing to save you, won't save you. I will now take up the word "faith," which means believing. THE BIBLE DEFINITION OF FAITH. People say, "What is faith?" Now the Bible definition of faith is perhaps as good as any one that we know of. We are told in Hebrews xi., "Now faith is the substance of things hoped for, the evidence of things not seen." Now faith is--what? The substance, or, as you have it in the margin, "ground" or "confidence." In other words, faith is dependence upon the veracity of another. Why, all business is carried on on this principle of faith. Let men lose confidence one in another, and see how quick business could cease here in London. Let men withdraw their confidence, and see what would take place in the commercial world to-morrow. It was faith that brought you here. If you had not faith to believe that there would be a meeting in this hall, you would not have come. Somebody said there are three things about faith--knowledge, assent, and laying hold, and it is the last clause that is safe. Not the knowledge. A great many people say, "I believe Christ is able to save." They give their assent, and say, "I believe" but that does not save. It is the last clause, the laying hold, that saves, and that is what we want to press upon you. Faith has an outward look, not an inward one. Hundreds of people spend time in looking at their own hearts, but FAITH IS AN OUTWARD LOOK.
