4. Having acquainted you with man's ultimate end and happiness in the life to come, the next thing to be taught you by the ministers of Christ, is, that Christ as our Saviour, and faith, and repentance, and sincere obedience to be performed by us through his grace, is the way to heaven, or the means by which we must attain this end. Though the knowledge of the preacher's wisdom, piety, and credibility remove some impediments which would make the receiving of this the more difficult to you, yet you are not to take it barely on his word, as a point of human faith; but you are to call for his proof of it, that you may see better reasons than his affirmations for the entertainment of it. [Sidenote: To know that this is true because God hath revealed it; or it is his word.] 5. The proof that he will give you is in these two propositions: 1. God's revelations are all true. 2. This is one of God's revelations: this is an argument, Whatsoever God saith is true: but this God saith, therefore this is true. The first proposition you are not to take upon the trust of his word, but to learn of him as a teacher to know it in its proper evidence; for it is the formal object of your faith: the veracity of God is first known to you, by the same evidence and means as you know that there is a God; and then it is by the force of this that you believe the particular truths which are the material object of faith. And the second proposition, that God hath revealed this, is orderly to be first proved, and so received upon its proper evidence; and not taken merely upon your teacher's word: yet if you do believe him by a human faith as a man that is likely to know what he saith, and this in order to a divine faith, it will not hinder, but help your divine faith and salvation; and is indeed no more than is your duty.
