"It is experience of ourselves, and finding what we are, that God commonly makes use of as the means of bringing us off from all dependence on ourselves. But men never get acquaintance with themselves so fast, as in the most earnest way of seeking [salvation]. They that are in this way have more to engage them to think of their sins, and strictly to observe themselves, and have much more to do with their own hearts, than others. Such a one has much more experience of his own weakness, than another that does not put forth and try his strength; and will therefore sooner see himself dead in sin. Such a one, though he hath a disposition continually to be flying to his own righteousness, yet finds rest in nothing; he wanders about from one thing to another, seeking something to ease his disquieted conscience; he is driven from one refuge to another, goes from mountain to hill, seeking rest and finding none; and therefore will the sooner prove that there is no rest to be found, nor trust to be put, in any creature whatsoever.

"It is therefore quite a wrong notion that some entertain, that the more they do, the more they shall depend on it. Whereas the reverse is true; the more they do, or the more thorough they are in seeking, the less will they be likely to rest in their doings, and the sooner will they see the vanity of all that they do.

[from "Pressing into the Kingdom of God"]

I believe we shall never learn to know ourselves except by endeavouring to know God, for, beholding His greatness we are struck by our own baseness, His purity shows our foulness, and by meditating on His humility we find how very far we are from being humble. 11.

When a man reflects on these things, studies all these created beings, from the angels and spheres down to human beings and so on, and realizes the divine wisdom manifested in them all, his love for God will increase, his soul will thirst, his very flesh will yearn to love God. He will be filled with fear and trembling, as he becomes conscious of his lowly condition, poverty, and insignificance, and compares himself with any of the great and holy bodies; still more when he compares himself with any one of the pure forms that are incorporeal and have never had association with any corporeal substance. He will then realize that he is a vessel full of shame, dishonor, and reproach, empty and deficient.

Knowing God without knowing our wretchedness leads to pride. Knowing our wretchedness without knowing God leads to despair. Knowing Jesus Christ is the middle course, because in him we find both God and our wretchedness.
