It is the A B C of God's alphabet. If a man is unsound on regeneration, he is unsound on everything. That is really the foundation-stone; and he must get the foundation right. If he don't, what is the good of trying to build a house? Now, Christ says plainly, "Except a man be born again, he cannot see the kingdom of God." But although regeneration or the new birth is taught so plainly in the third chapter of John, I don't believe there is any truth in the whole Bible that there is such great darkness about as this great truth. There are a great many like the man that saw men as trees walking. Many Christians do not seem to be clear about this new birth. BORN A CHRISTIAN. Only this afternoon, as I was in the inquiry-room, a person came in, and I said, "Are you a Christian?" "Why," she says, "of course I am." "Well," I said, "how long have you been one?" "Oh, sir, I was born one!" "Oh! indeed, then I am very glad to take you by the hand; I congratulate you; you are the first woman I ever met who was born a Christian; you are more fortunate than others; they are born children of Adam." She hesitated a little, and then tried to make out that, because she was born in England, she was a Christian. There are many who have the idea, that because they are born in a Christian country, they have been born of the Spirit. Now, in this third chapter of John, the new birth is brought out so plain, that if any one will read it carefully and prayerfully, I think his eyes will soon be opened. That which is born of the flesh is flesh; it remains flesh; and that which is born of the Spirit is spirit, and remains spirit. So, when a man is born of God, he has God's nature. When a man is born of his parents, he receives their nature, and they received the nature of their parents, and you can trace it back to Adam. But when a man is born of God, or born from above, or born of the Spirit--that is the way the Holy Ghost puts it in that third verse--he receives God's nature, and then it is he leaves the life of the flesh for the life of the spirit. Before I go on I want to say one thing, and that is, what this new birth, or being born of the Spirit, is not. A great many think they have been born again because they go to church. A great many say, "Oh, yes, I am a Christian; I go to church every Sabbath!" Let me say here that there is no one that goes to church so regularly in all London as Satan. He is always there before the minister, and he is the last one out of the church. There is not a church in London, or a chapel, but that he is a regular attendant of it. The idea that he is only down in the slums and lanes and alleys of London is a false idea. He is wherever the Word is preached; it is his business to be there, and catch away the seed. He is here to-night. Some of you may go to sleep, but he won't. Some of you may not listen to the sermon, but he will. He will be watching, and when the seed is just entering into some heart he will go and catch it away.
