If ye walk in my statutes. We have now to deal with two remarkable passages, in which he professedly treats of the rewards which the servants of God may expect, and of the punishments which await the transgressors. I have indeed already observed, that whatever God promises us on the condition of our walking in His commandments would be ineffectual if He should be extreme in examining our works. Hence it arises that we must renounce all the compacts of the Law, if we desire to obtain favor with God. But since, however defective the works of believers may be, they are nevertheless pleasing to God through the intervention of pardon, hence also the efficacy of the promises depends, viz., when the strict condition of the law is moderated. Whilst, therefore, they reach forward and strive, reward is given to their efforts although imperfect, exactly as if they had fully discharged their duty; for, since their deficiencies are put out of sight by faith, God honors with the title of reward what He gratuitously bestows upon them. Consequently, "to walk in the commandments of God," is not precisely equivalent to performing whatever the Law demands; but in this expression is included the indulgence with which God regards His children and pardons their faults. The promise, therefore, is not without fruit as respects believers, whilst they endeavor to consecrate themselves to God, although they are still far from perfection; according to the teaching of the Prophet, "I will spare them as a man spareth his own son that serveth him," (Malachi 3:17;) as much as to say, that their obedience would not be acceptable to Him because it was deserving, but because He visits it with His paternal favor. Whence it appears how foolish is the pride of those who imagine that they make God their debtor, as if according to His agreement. The restriction of the recompense, which is here mentioned, to this earthly and transitory life, is a part of the elementary instruction of the Law; for, just as the spiritual grace of God was represented to the ancient people by shadows and images, so also the same principle applied also both to rewards and punishments. Reconciliation with God was represented to them by the blood of cattle; there were various forms of expiation, but all outward and visible, because their substance had not yet appeared in Christ. For the same reason, therefore, because so clear and familiar an acquaintance with eternal life, and the final resurrection, had not yet been attained by the Fathers, as now shines forth in the Gospel, God for the most part shewed forth by external proofs that He was favorably disposed to His people or offended with them. Because now-a-days God does not openly take vengeance on sins as of old, fanatics infer that He has almost changed His nature; nay, on this pretense, the Manicheans [1] imagined that the God of Israel was different from ours. But this error springs from gross and disgraceful ignorance; for, by not distinguishing His different modes of dealing, they do not hesitate impiously to cut God Himself in two. The earth does not now cleave asunder to swallow up the rebellious: God does not now thunder from heaven as against Sodom: He does not now send fire upon wicked cities as He did in the Israelitish camp: fiery serpents are not sent forth to inflict deadly bites: in a word, such manifest instances of punishment are not daily presented before our eyes to make God terrible to us; and for this reason, because the voice of the Gospel sounds much more clearly in our ears, like the sound of a trumpet, whereby we are summoned to the heavenly tribunal of Christ. Let us then learn to tremble at that sentence, which banishes all the wicked from the kingdom of God. So, on the other hand, God does not appear, as of old, as the rewarder of His people by earthly blessings; and this because we "are dead, and our life is hid with Christ in God;" because it becomes us to be conformed to our Head, and through many tribulations to enter the kingdom of heaven. Thus, the greater are the adversities that oppress us, the more cheerfully it behooves us to lift up our heads, until Christ shall gather us into the fellowship of His glory, and to pursue the course of our calling for the hope which is set before us in heaven; in a word, "denying ungodliness and worldly lusts, to live soberly, righteously, and godly in this present world, looking for that blessed hope, and the glorious appearing of the great God, and our Savior Jesus Christ." (Titus 2:12, 13.) I admit, indeed, the truth of what Paul teaches, that "godliness" even now has "the promise of the life that now is, as well as of that which is to come," (1-Timothy 4:8;) and assuredly believers already taste on earth of that blessedness which they shall hereafter enjoy in its fullness. God also inflicts His judgments on the ungodly in order to remind us of the last judgment; but still the distinction to which I have adverted is obvious, that since God has opened to us the heavenly life in the Gospel, He now calls us directly to it, whereas He led the Fathers to it as it were by steps. For this reason Paul elsewhere teaches, that believers are afflicted in this world as "a manifest token of the righteous judgment of God, that they may be counted worthy of the kingdom of God for which they also suffer, seeing it is a righteous thing with God to recompense," etc. (2-Thessalonians 1:5, 6.) In short, let us no more wonder that the Israelites were only attracted and alarmed by temporal rewards and punishments, than that the land of Canaan was to them a symbol of their eternal inheritance, in which, nevertheless, they confessed themselves strangers and pilgrims; from whence the Apostle correctly concludes, that they desired a better country. (Genesis 47:9; Psalm 39:12; Hebrews 11:16.) And thus the wild absurdity of those is refuted, who suppose that the Fathers were contented with perishable felicity, as if God merely gorged them in a tavern. [2] Still the distinction which I have noted remains, that God manifested Himself more fully as a Father and Judge by temporal blessings and punishments than since the promulgation of the Gospel.
1 - "Through him (Manes) Christianity was to be set free from all connection with Judaism." -- Neander's Church Hist., (Rose's Transl.,) vol. 2, p. 145. "The theological error which naturally and immediately flowed from these principles, (i.e., the principles of Dualism,) was the entire rejection of the authority of the Old Testament. In respect to this question, Manes was compelled by his adoption of the oriental philosophy to reject the theosophy of the Jews." -- Waddington's Hist. of the Church, vol. 1 p. 154.
2 - "This discussion, which would have been most useful at any rate, has been rendered necessary by that monstrous miscreant Servetus, and some madmen of the sect of the Anabaptists, who think of the people of Israel as they would do of some herd of swine, absurdly imagining that the Lord gorged them with temporal blessings here, and gave them no hope of a blessed immortality." -- Institutes, B. 2. ch. 10. sect. 1. Cal. Soc. Trans., vol. 1, p. 501.
As "the book of the covenant" Exodus. 20:22-23:33 concludes with promises and warnings Exodus 23:20-33, so does this collection of laws contained in the Book of Leviticus. But the former passage relates to the conquest of the land of promise, this one to the subsequent history of the nation. The longer similar passage in Deuteronomy Deut. 27-30 is marked by broader and deeper promises and denunciations having immediate reference not only to outward consequences, but to the spiritual death incurred by transgressing the divine will.
If ye walk in my statutes - For the meaning of this and similar words used in the law, See the note on Leviticus 26:15.
If ye walk in my statutes, and keep my commandments, and do them. Both moral, ceremonial, and judicial, which had been delivered unto them, and now completely recorded in this and the preceding book; for what follow in the two next are chiefly repetitions of what are contained in these.
A BLESSING TO THE OBEDIENT. (Leviticus 26:3-13)
If ye walk in my statutes--In that covenant into which God graciously entered with the people of Israel, He promised to bestow upon them a variety of blessings, so long as they continued obedient to Him as their Almighty Ruler; and in their subsequent history that people found every promise amply fulfilled, in the enjoyment of plenty, peace, a populous country, and victory over all enemies.
The Blessing of Fidelity to the Law. - Leviticus 26:3-5. If the Israelites walked in the commandments of the Lord (for the expression see Leviticus 18:3.), the Lord would give fruitfulness to their land, that they should have bread to the full. "I will give you rain-showers in season." The allusion here is to the showers which fall at the two rainy seasons, and upon which the fruitfulness of Palestine depends, viz., the early and latter rain (Deuteronomy 11:14). The former of these occurs after the autumnal equinox, at the time of the winter-sowing of wheat and barley, in the latter half of October or beginning of November. It generally falls in heavy showers in November and December, and then after that only at long intervals, and not so heavily. The latter, or so-called latter rain, fall sin March before the beginning of the harvest of the winter crops, at the time of sowing the summer seed, and lasts only a few days, in some years only a few hours (see Robinson, Pal. ii. pp. 97ff.). - On Leviticus 26:5, Leviticus 26:6, see Leviticus 25:18-19.
