In verse 13 of the seventh of Leviticus we read, "He shall offer for his offering _leavened_ bread;" and yet at verse 20 we read, "But the soul that eateth of the flesh of the sacrifice of peace-offerings, that pertain unto the Lord, having his uncleanness _upon_ him, even that soul shall be cut off from his people." Here, we have the two things clearly set before us, namely, sin _in_ us and sin _on_ us. "Leaven" was permitted, because there was sin in the worshiper's nature: "uncleanness" was forbidden, because there should be no sin on the worshiper's conscience. If sin be in question, communion must be out of the question. God has met and provided for the sin, which He knows to be in us, by the blood of atonement; and hence, of the leavened bread in the peace-offering, we read, "Of it he shall offer one out of the whole oblation for a heave offering unto the Lord, and it shall be _the priest's that sprinkleth the blood of the peace-offerings_." (Ver. 14.) In other words, the "leaven" in the worshiper's nature was perfectly met by the "blood" of the sacrifice. The priest who gets the leavened bread must be the sprinkler of the blood. God has put our sin out of His sight forever. Though it be in us, it is not the object on which His eye rests. He sees only the blood, and therefore He can go on with us, and allow us the most unhindered fellowship with Him. But if we allow the "_sin_" which is in us to develop itself in the shape of "_sins_," there must be confession, forgiveness, and cleansing ere we can again eat of the flesh of the Peace-offering. The cutting off of the worshiper because of ceremonial uncleanness, answers to the suspension of the believer's communion now because of unconfessed sin. To attempt to have fellowship with God in our sins would involve the blasphemous insinuation that He could walk in companionship with sin. "If we say that we have fellowship with Him, and walk in darkness, we lie, and do not the truth." (1 John i. 6.)
