“ If he has heard it in its simplicity and purity, the weight of testimony which it bears along with it, carries conviction to his mind that it may be true, although, through the influence of the world, of evil associations in life, or the instigations of the enemy of all righteousness, those convictions and impressions may be swept away, which, if exercised at the time, in sincerity, with full purpose of heart to know the truth, would have substantiated the matter to his entire satisfaction. A weight of testimony always accompanies the promulgation of the Gospel of Salvation. ”
