But what is this sin, the consciousness of which is thus forced upon all--this determined, persistent, active evil? It is not the mere absence of good-a negative gain--but it is the love of, and the actual striving after that which is flatly condemned by God, and is in open rebellion against Him. The centreing of the corrupt heart upon its own corruption. Opposition to the pure will of God. Pride, falseness, unscrupulous ambition. Self-seeking, regardless of the means by which its object is obtained. Luxury, effeminacy, and sensuality. The lusts and fleshly passions. Malice, cruelty, and envy. The greed of gain. The love and thraldom of the world. There it is--the running sore of a suffering race. The outflow of the carnal mind, which is not subject to the law of God, neither indeed can be. There is no getting away from it. "Against this immovable barrier--the existence of sin--the waves of philosophy have dashed themselves unceasingly since the birth of human thought, and have retired broken and powerless, without displacing the minutest fragment of the stubborn rock, without softening one feature of its dark, rugged surface." And the worst of all is that sin is a wrong against God. _Man sins, of course, against himself._ That is written large on human affairs, so that no fool, however great a fool, may miss it. Well may the prophet say, "O Israel, thou hast destroyed thyself!" Men mix the hemlock for themselves! The sinner is a moral suicide! _Man sins against his fellow._ Nothing is more evident to us than that men tempt and corrupt one another. They hold one another back from righteousness. They break down virtue, and extinguish faith, and silence conscience in their neighbours. They act as decoys and trappers for each other's souls. They play the Devil's cat's-paws, and procure for him the rum of their fellows, which could not be compassed without their aid. In short, the sinner is a moral murderer! But, after all--and it is a hideous all--_the crowning wrong, and the crowning misery, is that sin is sin against God_. Unless the Bible be a myth, and the prophets a disagreeable fraud, and the whole lesson of Jesus Christ's life and death an illusion, God is deeply concerned with man. That concern extends to man's whole nature, his whole existence, his whole environment; and most of all it is manifest with regard to his sin. God puts Himself forward in the whole history of His dealings with men as an intimate, responsible, and observing Party in the presence of wrong-doing. He watches. He sees. He knows. He will consider. He will remember or He will forget. He will in no wise acquit the guilty, or He will pardon. Justice and vengeance are His, and so is forgiveness. He will weigh in the balances. He will testify against the evil-doer, or He will make an atonement for him. He will cut off and destroy, or He will have mercy. He will repay, or He will blot out.
