Quer 17. Can outward blood cleanſe the Conſcience? ye that are ſpiritual conſider, (Can outward water waſh the Soul clean?) Ye that have ever felt the blood of fprinkling from the Lord upon your Conſciences, and your Conſciences cleanſed thereby; did ye ever feel it to be outward? It is one thing what a man apprehends (in the way of notion ) from the Letter concerning the things of God, and another thing what a man feels in Spirit.
Quer. 18. Seeing the Apoſte ſpeaks of purifying the Heavenly things themſelves, Ebr. 9. 23. It would ſerouſly be inquired into, and the Lord waited on to know, what nature theſe Sacrifices muſt be of, which cleanſe the Heavenly things? Whether they muſt not of neceſſity be Heavenly? If ſo, then whether was it the fleſh and blood of the Vail, or the fleſh and blood within the, Vail? Whether was it the fleſh and blood of the outward earthly Nature, or the fleſh and blood of the inward ſpiritual Nature? Whether was it the fleſh and blood of the ſecond AdamsNature?
