Are you growing in grace? If not, you are graceless. If there is no movement, there is no life. If you are a Christian, there is in you a spiritual power of locomotion which will not let you rest. A Christian goes forth like the sun. Once indeed the sun paused at the command of Israel's leader; but there is no Gideon in the world mighty enough to stop the sunlike course of the Christian in the path of grace; nor is there a mount Gibeon to be found where you can bid him stand still. III. The Voice of Blood. AND TO THE BLOOD OF SPRINKLING, THAT SPEAKETH BETTER THINGS THAN THAT OF ABEL. HEB. 12:24. This is the last entry made in the rich inventory of spiritual blessings which Christians enjoy under the gospel economy. The blood of Christ shed upon the cross is called "the blood of sprinkling," in allusion to the blood of the paschal lamb; or more generally, to the blood of the burnt-offerings which was sprinkled upon and around the altar. The sprinkling of blood was, under the Levitical economy, the symbol of purification, as we are told by the apostle that "almost all things are, by the law, purged with blood." The text declares that the blood of Christ, shed for sinners, speaks better things than the blood of Abel, which was shed by the murderous hand of his brother, and called for vengeance. There has always seemed to be a strange, mysterious influence in blood shed by violence. It has a voice mightier than all other voices, which thrills the human soul with awful terror. Once the Almighty spoke in thunder from the blackened brow of Sinai; but generations before and after that, he spoke to men through the medium of blood. This was the language of all the divine sacrifices offered in the remotest times. The instructions of the whole Levitical economy were written in blood--blood upon the altar, upon the four horns of the altar, upon its sides, around it--ever speaking in language of deep and awful meaning to the worshipper. Man's blood shed by violence cannot be silenced. It has a cry which rings in the ears, a voice at which all living men start back aghast. It wails like an avenging fiend in the track of murder. It will not keep still. It summons the world to find out the guilty. The text introduces a contrast between the blood of Christ and that of Abel, or rather, between their utterances. Both spoke, and spoke with mighty power; but their language was far different. In the one it was _terror_, in the other _peace_.
