For the law, having a shadow of the good things to come, and not the very image of the things, can never with these same sacrifices, which they offer continually year by year, make those who approach perfect. – Hebrews 10:1

Christ is substance, and not shadow, fullness, and not foretaste. This is good news for us, for nothing but realities will meet our case. Types may instruct, but they cannot actually save. The patterns of the things in the heavens are too weak to serve our turn, we need the heavenly things themselves. No bleeding bird nor slaughtered bullock, nor running stream, nor scarlet wool and hyssop, can take away our sins.

“No outward forms can make me clean,
The leprosy lies deep within.”

Ceremonies under the old dispensation were precious because they set forth the realities yet to be revealed, but in Christ Jesus we deal with the realities themselves, and this is a happy circumstance for us; for both our sins and our sorrows are real, and only substantial mercies can counteract them. In Jesus, we have the substance of all that the symbols set forth. He is our sacrifice, our altar, our priest, our incense, our tabernacle, our all in all. The law had “the shadow of good things to come,” but in Christ we have “the very image of the things.” Hebrews 10:1. What transport is this to those who so much feel their emptiness that they could not be comforted by the mere representation of a truth, or the pattern of a truth, or the symbol of a truth, but must have the very substance itself! “The law was given by Moses, but grace and truth came by Jesus Christ.” ~ C.H. Spurgeon
