2. To exhort us, so to carry our selves as it becommeth those, that are called to partake of the life of Christ. Doctrine 17. _By that union which all the faithfull have with Christ, they are made spirituall temples, Priests, and sacrifices acceptable to God._ This is gathered from the 5 verse. _Reason_ 1. Because God is in an especiall manner present with them, and dwels in them by his Spirit and grace, as in his Temple, _2 Corinthians 6.16._ 2. Because By the same spirit he makes them fit and ready to performe those duties, that are more acceptable unto him, then were ever any externall sacrifices, _Psalme 51.18,19._ _Hebrews 13.16._ 3. Because in performing these duties before God they do offer and dedicate themselves wholly unto God. _Vse_ 1. This may serve to admonish us, to have a care accordingly not to defile the Temple of God, _1 Corinthians 3.16,17._ that our Priesthood doth not dishonour God, and that our Sacrifices be not lame, and maimed, and such as are not acceptable unto God. 2. To exhort us, to addict our selves wholly to Gods glory and his worship; for God will be sanctified in those that draw neere him, _Leviticus 10.3._ 3. To refute the Papists, that rob Christians of this honour, and obtrude carnall Temples, priesthoods, and sacrifices upon God and men in stead of spirituall. Doctrine 18. _Those duties which we performe in Christ are acceptable unto God by Christ._ This is gathered from the 5 verse, at the end. But they are acceptable not as merits, but as sacrifices of praise and thanksgiving, as it is intimated in the Text. _Reason_ 1. Because by Christ our persons are reconciled unto God, and received into the number of those whom God approves and by whom he delights to be worshipped. 2. Because Christ covers our infirmities. 3. Because by his intercession our duties are commended unto God. _Use_ 1. This may serve to comfort us, even when we looke upon our owne infirmities, and the unworthinesse of all our performances. 2. To exhort us, to go cheerefully about the duties of piety, because our worke shall not be in vaine in the Lord, _1 Corinthians 15.58._ Doctrine 19. _The same Christ was after the same manner a Saviour in the Old Testament, as he is in the New._ This is gathered from the sixth Verse. _Reason_ 1. Because he was a Lambe slaine from the foundation of the world; according to the decree, promise, and acceptance of God, and according to the faith and hope of the godly, _Apocalypse 13.8._ 2. Because the Catholick Church is but one, consisting of all the faithfull from the beginning of the world, _Hebrews 12.23._ _Use_ 1. This may serve to refute those, that make the people of Israel either to have beene altogether carnall, or to have beene saved by the observation of the Law. 2. To exhort us to flye unto Christ, and to put our confidence in him, in whom all the faithfull from the creation of the world did put their trust, and by whom they were saved.
