The surest way to know our gold, is to look upon it and examine it in God's furnace, where he tries it that we may see what it is. If we have a mind to know whether a building stands strong or not, we must look upon it when the wind blows. If we would know whether a staff be strong, or a rotten, broken reed, we must observe it when it is leaned on and weight is borne upon it. If we would weigh ourselves justly we must weigh ourselves in God's scales that he makes use of to weigh us.
Jonathan EdwardsAll the fruits of the Spirit which we are to lay weight upon as evidential of grace, are summed up in charity, or Christian love; because this is the sum of all grace. And the only way, therefore, in which any can know their good estate, is by discerning the exercises of this divine charity in their hearts; for without charity, let men have what gifts you please, they are nothing.
Jonathan EdwardsHow can you expect to dwell with God forever, if you so neglect and forsake him here?
Jonathan EdwardsSo that it must be only by the imagination that Satan has access to the soul, to tempt and delude it, or suggest anything to it. And this seems to be the reason why persons that are under the disease of melancholy are commonly so visibly and remarkably subject to the suggestions and temptations of Satan... Innumerable are the ways by which the mind may be led on to all kind of evil thoughts, by the exciting of external ideas in the imagination.
