10. The believer likewise would act faith upon the promises of the new covenant, of grace, strength, life, &c, whereby they shall walk in his ways, have God’s laws put into their minds, and wrote in their hearts, Heb. viii. 10. Jer. xxxi. 33; and of the new heart, and new spirit, and the heart of flesh, and the Spirit within them, to cause them walk in his ways or statutes, and keep his judgments, and do them, Ezek. xxxvi. 26, 27, and the like, wherewith the Scripture aboundeth; because these are all given over to the believer by way of testament and legacy, Christ becoming the Mediator of the New Testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance, Heb. ix. 15. Now, Christ, by his death, hath confirmed this testament; “for where a testament is, there must also of necessity be the death of the testator; for a testament is of force after men are dead,” vers. 16, 17. Christ, then, dying to make the testament of force, hath made the legacy of the promises sure unto the believer; so that now all the “promises are yea and amen in Christ,” 2 Cor. i. 20. “He was made a minister of circumcision to confirm the promises made to the fathers,” Rom. xv. 8. That the eyeing of these promises by faith is a noble mean to sanctification, is clear, by what the apostle saith, 2 Cor. vii. 1, “Having therefore these promises, let us cleanse ourselves; perfecting holiness in the fear of God.” And it is by faith that those promises must be received, Heb. xi. 33: So that the believer that would grow in grace, would eye Christ, the fundamental promise, the testator establishing the testament, and the executor or dispensator of the covenant, and expect the good things through him, and from him, through the conduit and channel of the promises.
11. Yet further, believers would eye Christ in his resurrection, as a public person, and so look on themselves, and reckon themselves as rising virtually in and with him, and take the resurrection of Christ as a certain pawn and pledge of their sanctification; for so reasoneth the apostle, Rom. vi. 4, 5, 11, 13. “We are buried,” says he, “with him by baptism unto death; that like as Christ was raised up from the dead by the glory of the Father, even
