The Book of Habakkuk is a classic example of what we would call a theodicy. It serves as a defense of the goodness of God in the midst of evil. A theodicy aims to solve the paradox of His general providence in a world of pain and misery. How could an all-loving, all-knowing, all-powerful God allow us to go through bad things? Why do evil people seem to prosper while the righteous suffer, being continually trampled on? Why is perfect justice not always inflicted on evildoers in this world? Questions of this nature undoubtedly plagued the mind of Habakkuk. Countless people through history have pondered and debated at length about such issues. Habakkuk was troubled deeply by the corrupt society in which he lived. The laws of the prophet's own nation were not being enforced. Justice was nowhere to be found in the land. Rebellion toward God abounded. Habakkuk wondered how a righteous God could be silent and allow these things to come to pass. Why does He stand by and do nothing? The prophet raised such questions not in a state of doubt, but faith. While God did not specifically answer the why behind that man's questions, the response given aroused a greater sense of perplexity than he originally had. How could a righteous God use Babylon, a nation more wicked than Judah itself, as an instrument of divine judgment?
The underlying theme of the Book of Habakkuk is that we can place our trust in God because of His sovereignty. This sovereignty is not merely a distant, impersonal force, but an active, personal involvement in the lives of those who love Him. God is working things out for the good of those who love Him, directing events in ways that we may not immediately understand but are always under His divine control. Whether things seem impossible to us is irrelevant to God. His omnipotence transcends human limitations and comprehension. He will right the wrongs of evildoers in His own perfect timing. That means justice, although delayed in our eyes, is inevitable under His watchful gaze. His plan, while it may seem convoluted and slow from our finite perspective, will prove satisfactory to us in the grand scheme or complete picture of all events when they are brought to a close. This assurance invites us to adopt a posture of patience and faith. Habakkuk contains a passage that is quoted twice by the Apostle Paul in the context of our justification before God, particularly Romans 1:17 and Galatians 3:11. The text being discussed is cited in its entirety as follows:
"Behold, as for the impudent one, His soul is not right within him; But the righteous one will live by his faith." (Habakkuk 2:4)
Habakkuk was told by God to write down a message of the ruination of the Babylonian Empire and the restoration of Judah. The king of Babylon would die as a result of being conceited. God would preserve a small remnant of Jews who were obedient to His commandments. The Babylonian army was brutal in conquest. Captured leaders were humiliated. A series of woes is pronounced on Nebuchadnezzar for his greed, covetousness, and cruelty. It is a truth that God judges people who are arrogant and presumptuous. He brings down people who presumptuously esteem their might and capabilities (Numbers 14:44). Habakkuk 2:4 contains a description true of human nature in that we fail to properly honor God. The Babylonian Empire was stooped in moral corruption. It used threats and force to enrich itself monetarily (Habakkuk 2:6). Babylon pillaged and plundered other nations. It slaughtered innocent people and destroyed their homes (Habakkuk 2:8). These actions are denounced by God as being cruel. The Babylonians would pay by their own self-destruction.
What did the Apostle Paul see in this passage that made it relevant to his teaching of justification by faith in Romans and Galatians? Did he misunderstand the words of Habakkuk? Paul sees in this passage the foundation of the message of the gospel in which man is declared righteous by God apart from the merit of good deeds. He projects the scope of the prophet's words from an ethnic group whose existence is in peril and infuses them with a new meaning that relates to our common humanity. Certainly, Habakkuk's words are broad enough to fit with Paul's application of them. The apostle's message could be paraphrased in this manner: "the one justified by faith shall live." He concerns himself with the reception of spiritual life. Habakkuk 2:4 is the only text besides Genesis 15:6 that brings together faith and righteousness in the Old Testament. Thus, we see the reason for Paul appealing to them in his argumentation against Law observance for justification before God in Romans and Galatians. A righteousness that comes by faith is antithetical to a Law righteousness.
The Apostle Paul's point of emphasis in Romans 1:17 is that the person who has been justified by faith is to live a life of faith. We receive a righteousness from God that does not belong to us and is based on Christ's propitiatory work on the cross. The Hebrew-Greek Key Word Study Bible, edited by Spiros Zodhiates, has this excerpt on Romans 1:17, "The expression "from faith to faith" is merely an intensive form meaning faith alone." Paul was a Hebrew who used expressions in the manner of that found in the Old Testament. Phrases comparable to "from faith to faith" in Romans 1:17 would include "vanity of vanities" (Ecclesiastes 1:2), "holy of holies" (Exodus 26:34), and "heaven of heavens" (Deuteronomy 10:14). Another occurrence of this form occurs when Paul described himself as "Hebrew of Hebrews" (Philippians 3:5). He interpreted the Prophet Habakkuk's words about a faithful Jewish remnant that appeared to be on the brink of utter destruction as being words of hope for lost humanity. Faith initiates the process of salvation and is its goal. God continually saves believers from the grasp of sin. The condition for Jews to receive blessings and protection from God under the Old Covenant is the same for Christians under the New Covenant: faith. A man cannot obtain a just standing before Him without it. Faith, righteousness, and life are intertwined. God's comfort and security are for all believers.
Paul in Galatians 3:11 gives weight to Habakkuk 2:4 with the intent of making the point that one is justified in the sight of God on the basis of faith. He uses something other than the Law to make us right with Him. It is a life of faith that glorifies God. It is that kind of a life which brings honor to Him. The Apostle Paul's teaching of living by faith is to be contrasted with the Law's requirement of "doing" in order to have life (Deuteronomy 27:26; Leviticus 18:5). The latter way brings about death and is, therefore, of no avail to us in getting a righteous standing before God. Within the context of Leviticus, the decrees, statutes, and issued judicial rulings were the means of every aspect of Jewish life. They covered the physical, moral, and spiritual aspects of society. The Law brought death when violated, and the death of David and Bathsheba's son out of wedlock is an active illustration of this point. The Law points to life because it lays out the path of righteousness. However, it brings death to us because sin controls our nature. In the Greek text of Galatians 3:11, the word "by" means to be under the control or according to the nature of. We obtain a righteous standing before God by faith. We are freed from the guilt of sin by grace through faith. That is the newness of life we have in Christ.
Hebrews 10:38 is the third and final place of the New Testament that contains a citation of Habakkuk 2:4. While the author of the Epistle to the Hebrews is unknown, the text bears mentioning here because it addresses the enduring nature of faith. The context of Hebrews 10 is not justification before God, but persevering in doing the will of God. Hebrews 10 stresses the continuity that exists between one's profession of faith and faith outwardly being lived out. There is also a contrast in verse 38 between two types of people. The people whom God considers as righteous are those who long for the fulfillment of His eternal promises, which as of yet cannot be seen. They endure persecution and so secure for themselves an inheritance that cannot perish. The anonymous author in the next chapter proceeds to give examples of such people from the Old Testament who rejected worldly comfort and pleasure in favor of eternal blessings. Their focus was on the future, not there and then. All of the faithful will be richly rewarded by God in the life to come. The person who succumbs to persecution is regarded as one in whom He "takes no pleasure." He is not invested in such people or showcasing divine favor to them. That course of action is called apostasy, of which is clearly frowned upon.
Some translations of the Bible use the word "faith" in Habakkuk 2:4 (New King James Version, English Standard Version, New American Standard Bible, etc.), while others have "faithfulness" (New International Version, New English Translation, etc.). Either choice of wording is acceptable in this context. The Hebrew word "emunah," used in this verse, can be translated as "faith," "faithfulness," "steadfastness," or "trustworthiness," capturing both an inward belief and outward demonstration. The LXX Septuagint translation says, "the just shall live by my faith," as if God's faithfulness is in view. However, that reading of the text is not taken into consideration here. A man who has faith is one who trusts in God. Such a man's character is honorable and reliable. His ways are morally upright. Those who have faith in God will also believe His promises. They are loyal to His covenant. The Apostle Paul would have derived his understanding of faith from the Old Testament Scriptures. By rooting our understanding in that same source, we can gain a fuller appreciation of this profound interplay between belief, action, and divine reliability. David W. Kerr, in the Wycliffe Bible Commentary, p. 876, writes concerning the nature of faith and faithfulness:
"...In most places in the OT where it [faith] is used it has the second meaning [faithfulness rather than faith], for example, in II Kgs 12:15; Jer 5:1. It is, however, worth noticing that the root of this word [Hebrew emunah] has already been used in Hab 1:5 in the sense of giving credence to God's word or promise. Moreover, faithfulness, even as an aspect of a man's character, does not occur in the void. Faithfulness must be exercised in relation to someone or something. In this case the individual is to be faithful to God, to God's word and covenant. He must rely firmly upon, or have a deep-rooted trust in God himself. The NT use is in complete agreement with this."
The same author cited before reflects on Paul's usage of Habakkuk 2:4 and his spiritualization of the concept of life:
"...Paul, in comparison with Habakkuk, enlarges infinitely the scope of the word "live," for he applies it to life to come, to the sphere of salvation or eternal well-being in distinction from merely temporal well-being. That the apostle is justified in doing so will readily be granted by Christians, since the NT writers employ many forms and figures of the OT with a fullness of meaning far transcending that which they had for believers under the older dispensation. Finally, the antithesis between the principle of active faith and that of meritorious law-works as a means of salvation is, of course, a part of the apostle's own argument. It is a logical development from the nature of faith itself."
Martin Franzmann and Walter H. Roehrs, in the Concordia Self-Study Commentary, p. 639, say about the nature of faith as it relates to Habakkuk's prophecy and Paul's conceptualization of it:
"The word faith occurs only once in Habakkuk (2:4); but his whole prophecy is a word of faith, faith agonized, questioning, seeking, finding repose in God, and jubilant, finally, in assurance of God's love, and all this in the face of the obstacle to faith posed by God's scandalously mysterious governance of history. When Paul quotes 2:4 in his thematic statement of justification by faith in Ro 1:17, it is only fair to assume that he is quoting with a consciousness of this original context of faith in Habakkuk. For Paul, as for Habakkuk, faith is confronted by an action of God which is offensively enigmatic, namely, the weakness and foolishness of the Cross; for both Paul and Habakkuk faith is faith without works, for both it is "quietly waiting" for God to do His saving work. For both, faith is not one aspect of man's existence before God but the whole of his relationship to Him."
