Since holiness is the main thing that excites, draws, and governs all gracious affections, it is no wonder that all such affections tend to holiness. That which men love, they desire to have and to be united to, and possessed of. That beauty which men delight in, they desire to be adorned with. Those acts which men delight in, they necessarily incline to do.

So 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.

Almost all men, and those that seem to be very miserable, love life, because they cannot bear to lose sight of such a beautiful and lovely world. The ideas, that every moment whilst we live have a beauty that we take not distinct notice of, brings a pleasure that, when we come to the trial, we had rather live in much pain and misery than lose.

A truly humble man is sensible of his natural distance from God; of his dependence on Him; of the insufficiency of his own power and wisdom; and that it is by God's power that he is upheld and provided for, and that he needs God's wisdom to lead and guide him, and His might to enable him to do what he ought to do for Him.

God is the highest good of the reasonable creature. The enjoyment of him is our proper; and is the only happiness with which our souls can be satisfied. To go to heaven, fully to enjoy God, is infinitely better than the most pleasant accommodations here. Better than fathers and mothers, husbands, wives, or children, or the company of any, or all earthly friends. These are but shadows; but the enjoyment of God is the substance. These are but scattered beams; but God is the sun. These are but streams; but God is the fountain. These are but drops, but God is the ocean.
