Note, 1. God is the God of nature, and all the powers and faculties of
nature are derived from him and depend upon him, and therefore are to
be employed for him. It was he that formed the eye and planted the ear
(Ps. xciv. 9), and the structure of both is admirable; and it is he
that preserves to us the use of both; to his providence we owe it that
our eyes are seeing eyes and our ears hearing ears. Hearing and seeing
are the learning senses, and must particularly own God's goodness in
them. 2. God is the God of grace. It is he that gives the ear that
hears God's voice, the eye that sees his beauty, for it is he that
opens the understanding.
