I do not know that I need say more concerning believing. I have often tried to explain it, I am afraid that I have not always made it as plain as I have intended. Only let me warn you not to say, “I understand the plan of salvation very well. Dear Sir, I am sure I do; I do not need it explained to me, I understand it perfectly.” My dear friend, it is one thing to understand the plan of salvation, and quite another thing to believe in Jesus Christ to the salvation of your soul. It is a pitiless night, the rain is pouring down, and hero is a man, Sitting out in the street, exposed to the ill weather, and he has got a plan of a house down there on the wet pavement, and he says, “I am all right; I understand the plan of a house quite well.” You see, he is looking at the plan; he has a view of the front of the house, he knows where the windows and doors should be; and he has a ground plan, too; he can see where the kitchen is, and the passage to the kitchen, and he knows the arrangement of all the rooms. But, my dear fellow, you are getting wet through; the storm is raging, why do you not go into the house for shelter? “Do not talk to me,” says he, “I understand the plan of a house very well.” The man is a fool if he talks like that; everybody concludes that he is out of his mind; and what is he who is satisfied with understanding the plan of salvation, but who does not come to Christ, and put his trust in him? Come to him now, I beseech you. You who do not know so much about the plan of salvation, come to Jesus, come and trust him; trust him now.
