Who will have all men to be saved, and to come unto the knowledge of the truth. – ! Timothy 2:4

I have known men, when first they have come to a knowledge of this truth, become unable to sleep. They have started up in the night. They have asked those who were with them to help them to pray. The next day they have been scarcely able to mind their business, for a dreadful sound has been in their ears. They feared lest they should stumble into the grave and into hell. Thus they were saved from carelessness. They could not go back to be the mere brute beasts they were before. Their eyes had been opened to futurity and eternity. Their spirits had been quickened-at least so much that they could not rest in that doltish, dull, dead carelessness in which they had formerly been found. They were shaken out of their deadly lethargy by a knowledge of the truth…Often when men are awakened to know something about the wrath of God they begin to plunge about to discover divers methods by which they may escape from that wrath…Under such untruthful notions we have known people who were somewhat aroused sit down again in a false peace. They have done all that they judged right and attended to all that they were told. Suddenly, by God’s grace, they come to a knowledge of another truth, and that is that by the deeds of the law there shall no flesh be justified in the sight of God. They discover that salvation is not by works of the law or by ceremonies, and that if any man be under the law he is also under the curse. Such a text as the following comes home, “Not of blood, nor of the will of the flesh, nor of the will of man, but of God,” and such another text as this, “Ye must be born again,” and then this at the back of it-“that which is born of the flesh is flesh, and that which is born of the Spirit is spirit.” When they also find out that there is necessary a righteousness better than their own, a perfect righteousness to justify them before God, and when they discover that they must be made new creatures in Christ Jesus, or else they must utterly perish, then they are saved from false confidences, saved from crying, “Peace, peace,” when there is no peace. It is a grand thing when a knowledge of the truth stops us from trusting in a lie. ~ C.H. Spurgeon
