1. There is such a Confusion and darkness in the Soul of man, especially of an unregenerate man, that he can scarcely tell what he doth, or what is in him. As one can hardly finde any thing in a house where nothing keeps his place, but all is cast on a heap together; so is it in the heart where all things are in disorder, ••∣specially when darkness is added to this disorder; so that the heart is like an obscure Cave or Dungeon, where there is but a little crevise of light, and a man must rather grope then see.

The first common excellency that they meet with in themselves, doth so dazle their eyes, that they are presently satisfied that all is well, and look no further.
5. Besides, most men do search but by the halves. If it will not easily & quickly be done, they are discouraged, and leaveoff. Few set to it and follow it, as beseems them in a work of such moment. He must give all diligence that means to make sure.
6. Also men try themselves by false Marks and Rules; not knowing wherein the truth of Christianity doth consist; some
