But how was this lamb to be eaten? "With unleavened bread and bitter herbs." Leaven is invariably used, throughout Scripture, as emblematical of evil. Neither in the Old nor in the New Testament is it ever used to set forth anything pure, holy, or good. Thus, in this chapter, "the feast of unleavened bread" is the type of that practical separation from evil which is the proper result of being washed from our sins in the blood of the Lamb, and the proper accompaniment of communion with His sufferings. Naught but unleavened bread could at all comport with a roasted lamb. A single particle of that which was the marked type of evil, would have destroyed the moral character of the entire ordinance. How could we connect any species of evil with our fellowship with a suffering Christ? Impossible. All who enter, by the power of the Holy Ghost, into the meaning of the cross will assuredly, by the same power, put away leaven from all their borders. "For even Christ our passover is sacrificed for us: _therefore_ let us keep the feast, not with old leaven, neither with the leaven of malice and wickedness; but with the unleavened bread of sincerity and truth." (1 Cor. v. 7, 8.) The feast spoken of in this passage is that which, in the life and conduct of the Church, corresponds with the feast of unleavened bread. This latter lasted "seven days;" and the Church collectively, and the believer individually, are called to walk in practical holiness, during the seven days, or entire period, of their course here below; and this, moreover, as the direct result of being washed in the blood, and having communion with the sufferings of Christ.
The Israelite did not put away leaven in order to be saved, but because he was saved; and if he failed to put away leaven, it did not raise the question of security through the blood, but simply of fellowship with the assembly. "Seven days shall there be no leaven found in your houses: for whosoever eateth that which is leavened, even that soul shall be cut off from the congregation of Israel, whether he be a stranger, or born in the land." (Ver. 19.) The cutting off of an Israelite from the congregation answers precisely to the suspension of a Christian's fellowship, if he be indulging in that which is contrary to the holiness of the divine presence. God cannot tolerate evil. A single unholy thought will interrupt the soul's communion; and until the soil contracted by any such thought is got rid of by confession, founded on the advocacy of Christ, the communion cannot possibly be restored. (See 1 John i. 5-10.) The true-hearted Christian rejoices in this. He can ever "give thanks at the remembrance of God's holiness." He would not, if he could, lower the standard a single hair's breadth. It is his exceeding joy to walk in company with One who will not go on, for a moment, with a single jot or tittle of "leaven."
Blessed be God, we know that nothing can ever snap asunder the link which binds the true believer to Him. We are "saved in the Lord," not with a temporary or conditional, but "with an everlasting salvation." But then salvation and communion are not the same thing. Many are saved who do not know it; and many, also, who do not enjoy it. It is quite impossible that I can enjoy a blood-stained lintel if I have leavened borders. This is an axiom in the divine life. May it be written on our hearts! Practical holiness, though not the basis of our _salvation_, is intimately connected with our _enjoyment_ thereof. An Israelite was not saved by unleavened bread, but by the blood; and yet leaven would have cut him off from communion. And as to the Christian, he is not saved by his practical holiness, but by the blood; but if he indulges in evil, in thought, word, or deed, he will have no true enjoyment of salvation, and no true communion with the Person of the Lamb.
