This is gathered from these words: _Ye do well that ye take heed_. By _taking heed_ is meant, 1. A search and inquiry after the sense of the Scriptures, or the truths that are contained in them. 2. An applying of those truths unto the ends and uses whereunto they serve. 3. A religious affection of the minde, whereby the conscience is subdued unto those truths as unto the rules of faith and manners: how they do well, that do thus give heed unto the Scriptures. _Reason_ 1. Because this obedience pleaseth God. 2. Because they provide well for themselves, to be directed unto eternall happinesse. _Vse_ 1. This may serve to refute the Papists, and some other foolish men, who deny that they do well, which give heed unto the Scriptures. 2. To reprove all profane and worldly men, who take great care about their worldly profits, or their carnall pleasures, but give little or no heed at all unto the Scriptures. 3. To exhort us, to stirre up in our selves daily this care of attention. Doctrine 4. _The Scripture is a light shining unto those that religiously give heed unto it._ This is gathered from these words, _Take heed as unto a light that shineth_. Now it is called a light, _Reason_ 1. Because it is cleare and manifest in it selfe. 2. Because it makes all other things cleare and manifest. 3. Because it enlightens also the eyes of our minde, so that we are able to behold the heavenly mysteries of the kingdome of God. _Vse_ 1. This may serve to refute the Papists, who tax the Scriptures of obscurity. 2. To reprove and condemne those, that walk in the midst of this light, and yet perceive no more of the things of God, then as if they were in darknesse. 3. To exhort us, 1. To give God thanks for so great a benefit. For God now deales with us, as he did heretofore with the Israelites, in whose dwellings there was light, when in all the land of the Egyptians there was thick darknesse, _Exodus 10.22,23._ 2. To walke in this light, not to sleepe or have fellowship with the workes of darknesse, as it is _Ephesians 5.8,11,14._ Doctrine 5. _The whole condition of this our life hath much darknesse in it._ This is gathered from these words; _A light shining in a darke place._ We may see the explication of these words in _Calvin_. _Reason._ Because without the light of the Scriptures and faith we are nothing but darknesse; seeing therefore this light is communicated unto us but imperfectly in this life, there must needs be as yet much darknesse. _Use_ 1. This may serve to admonish us, not to puffe up our selves with the opinion of knowledge, but humbly to acknowledge our imperfections. 2. To exhort us, so much the more diligently to give heed unto the light. Doctrine 6. _We must give heed unto the Scriptures, untill a greater light be communicated unto us, then we can have out of the Scriptures, that is, untill the last end of this life._
