Grace not only saves the soul with an everlasting salvation, but also imparts a nature which delights in everything that belongs to God, because it is divine. We are made partakers of the divine nature, which cannot sin, because it is born of God. To walk in the energy of this nature is, in reality, to "keep" the feast of unleavened bread. There is no "old leaven" nor "leaven of malice and wickedness" in the new nature, because it is of God, and God is holy, and "God is love." Hence it is evident that we do not put away evil from us in order to better our old nature, which is irremediable; nor yet to obtain the new nature, but because we have it. We have life, and, in the power of that life, we put away evil. It is only when we are delivered from the guilt of sin that we can understand or exhibit the true power of holiness. To attempt it in any other way is hopeless labor. The feast of unleavened bread can only be kept beneath the perfect shelter of the blood.
We may perceive equal significancy and moral propriety in that which was to accompany the unleavened bread, namely, the "bitter herbs." We cannot enjoy communion with the sufferings of Christ without remembering what it was which rendered those sufferings needful, and this remembrance must necessarily produce a chastened and subdued tone of spirit, which is aptly expressed by the bitter herbs in the paschal feast. If the roasted lamb expressed Christ's endurance of the wrath of God in His own Person, on the cross, the bitter herbs express the believer's recognition of the truth that He "suffered _for us_." "The chastisement of our peace was upon Him, and with His stripes we are healed." (Isaiah liii. 5.) It is well, owing to the excessive levity of our hearts, to understand the deep meaning of the bitter herbs. Who can read such psalms as the sixth, twenty-second, thirty-eighth, sixty-ninth, eighty-eighth, and one hundred and ninth, and not enter, in some measure, into the meaning of the unleavened bread with bitter herbs? Practical holiness of life, with deep subduedness of soul, must flow from real communion with Christ's sufferings; for it is quite impossible that moral evil and levity of spirit can exist in view of those sufferings.
