Augustine of Hippo
Beloved, take note of the psalm I am about to expound, through God’s grace, our expectation in the Lord Jesus Christ. Take heart, for He who has made promises will bring them to pass, just as He has already done much. Our assurance stems not from our own merits but from His grace. The name "Ethan" in this context refers to the Israelite who gives this psalm its title. Clearly, Ethan signifies strength, underscoring that no one in this world is truly strong except in the hope of God's promises; apart from His mercy, we are weak. Thus, the psalmist begins, "I will sing of Your mercies, O Lord, forever; with my mouth, I will proclaim Your truth to all generations" (Psalms 88:1).
He continues, "Let my words serve the Lord." What I express are Your words. I declare Your truth; without obedience to You, I am not Your servant. Speaking from You and from myself represents two different things: one pertains to me, the other to You; Your truth is in my tongue. Let us examine the faithfulness He exhibits and the graces He sings of.
You have declared, "Grace shall be established forever" (Psalm 87:2). This is the truth I sing: this is Your message for me to proclaim. You say, "I build not to destroy," for while some are destroyed, others are not rebuilt; yet, some whom You do destroy, You reconstruct. If there were no destruction followed by rebuilding, Jeremiah would not have written, "Behold, I have appointed you today to uproot and to build" (Jeremiah 1:10). Those who previously worshipped idols could not find stability in Christ and perished in their former errors. If some were not destroyed so that they might not be built up again, it would not have been recorded, "He will destroy them and not restore them."
Thus, these terms—mercy and truth—are intertwined. You have stated, "Mercy shall be established forever; Your truth shall be confirmed in the heavens," where mercy and truth are reiterated, for the Lord’s ways are filled with mercy and truth. The reality of truth in fulfilling promises cannot come to light without mercy in forgiving sins. Alongside this, many prophecies were made to the people of Israel, who descended from Abraham, promising that God’s promises would manifest within them. Yet, God did not withhold His goodness from the Gentiles, whom He entrusted to angelic beings while preserving Israel as His chosen people. The apostle refers to the Lord’s mercy and truth regarding these two groups and identifies Christ as the minister to the Jews, affirming the promises made to the fathers (Romans 15:8).
Observe that God has not misled or abandoned His foreknown people. While the apostle speaks of the fall of the Jews, he emphasizes that God has not cast away the people He knew beforehand, for "I also am an Israelite" (Romans 11:1-2). Even if all Israel were thorns, what can I say about the wheat? The truth of God is fulfilled among the Israelites who believe, where one wall of circumcision is built upon the cornerstone. Yet, this stone could not stand as the cornerstone without receiving a different wall from the Gentiles; the first wall pertains specifically to truth, while the second relates to God’s grace. The apostle thus asserts that Jesus Christ was a minister for truth to confirm the promises made to the fathers, enabling the Gentiles to glorify God for His mercy (Romans 15:8-9).
It is rightly added, "You will confirm Your truth in the heavens," for all the Israelites who were called to be apostles became representatives of heaven, proclaiming God's glory, as it is written, "The heavens declare the glory of God, and the firmament shows His handiwork." Even though they were taken before the Church spread globally, their words reached the ends of the earth, thus confirming, "You will establish Your truth in the heavens that are within them."
You have declared, "I have made a covenant with My chosen" (Psalm 88:3). What covenant other than a new covenant that renews us for a fresh inheritance, instilling longing and love, inspiring us to sing a new song? The psalmist notes this covenant—“I have sworn to David my servant.” How boldly he speaks, understanding and articulating the truth! I speak without trepidation, for You have declared. If Your words make me fearless, how much more secure am I because You have sworn! God's oath is the surety of promise fulfillment. Humans are justly cautioned against swearing (Matthew 5:34) to avoid the pitfalls of perjury; only God, who is infallible, swears safely.
Let us examine what God has sworn. He states, "I have sworn to David my servant; I will establish your offspring forever" (Psalm 87:4). But what is David’s offspring if not Abraham’s? As it is written, "To your offspring," referring to Christ (Galatians 3:16). Christ, the Head of the Church and the Savior of the body (Ephesians 5:23), is indeed Abraham’s seed. Yet are we not also the seed of Abraham? Certainly, as the apostle says, "If you are Christ’s, then you are Abraham’s offspring and heirs according to the promise" (Galatians 3:29).
Hence, we should grasp the words, dear brethren: "I will establish your offspring forever," not just through the flesh of Christ born of the Virgin Mary but also through all of us who believe in Him. For we are members of this Head, which cannot be separated from its Body; if the Head resides in eternal glory, so do the members, assuring that Christ remains whole forever. "I will establish your offspring forever, and I will maintain your throne from generation to generation." This notion of “forever” corresponds to the generations and kinship established previously, as stated: "With my mouth I will always display Your truth to every generation."
What is meant by “generation to generation”? It refers to every generation; thus, the repeated phrase highlights the ongoing line of generations. We can understand two generations in this context, my beloved brethren, as I've previously indicated: there exists the current generation of flesh and blood and a future resurrection of the dead. Christ is proclaimed here and will be proclaimed there, believed in here, and glorified there. "I will establish your throne from generation to generation." Christ currently reigns in us; if He were not enthroned within us, He would not govern us. If we were not under His reign, we would fall into ruin. Therefore, He takes His rightful place within us, governing us, and also awaits another generation to arise from the resurrection. Christ shall reign over His saints forever. God has assured it; He has declared it—if this does not suffice, God has also sworn it.
Thus, since the promise is credible—not owing to our merit but to His mercy—no one should fear to proclaim what cannot be doubted. May this power fill our hearts, reminiscent of Ethan's name, meaning “strong in heart.” Let us declare the truth of God, His proclamations, promises, and oaths, and thus strengthened on all sides, glorify God and, by bringing Him with us, become heavenly.
"O Lord, even the heavens will praise Your marvelous works" (Psalm 88:5). It is not on their own merits that the heavens offer praise, but for Your wondrous deeds, O Lord. In every act of mercy towards the lost, in justifying the unjust, what are we celebrating but the extraordinary works of God? You exalt Him for raising the dead; commend Him even more for redeeming the lost. What grace, what mercy of God! You witness a man, once mired in drunkenness, transformed into a beacon of sobriety; a man, previously characterized by excess, now exemplifying temperance; a man, once a blasphemer, now proclaiming God's praise; a slave to sin, now a worshipper of the Creator. Through these drastic transformations, let them not rely on their own merits; let them ascend to the heavens and extol the marvelous works of the One who made them anew.
"Who among the clouds can be compared to You, O Lord?" (Psalm 88:6). Will it be the praise of the heavens or their rain? Is there certainty that none among the clouds measures up to the Lord? Does it seem to you, brethren, it's a grand commendation that the clouds cannot match their Creator? Taken literally, isn't this perspective skewed? Can the stars above the clouds compare to the Lord? Can the sun, moon, angels, or heavens measure up to Him? Thus, why does the psalmist ask, "Who is He among the clouds?" We grasp, dear brethren, that these clouds, like heaven, serve as conveyors of truth—prophets and apostles heralding God's Word.
If clouds are preachers of truth, we must first inquire why they are referred to as clouds. They represent both heaven and clouds: heaven emerging from the brilliance of truth, while clouds symbolize obscurities tied to mortality, marked by the transient nature of flesh. It is of these mortal obscurities that the apostle says, "Therefore do not judge anything before the time, until the Lord comes, who will illuminate the hidden things of darkness" (1 Corinthians 4:5). You may discern a man's spoken words; however, the depths of his heart remain unrevealed. What pours from the cloud is seen, yet what remains hidden within it is unnoticed. Who possesses the sight to pierce through the cloud? Thus, clouds serve as fleshly messengers of truth. The Creator came down, embracing flesh.
We are styled clouds because of our flesh, and we convey truth through the outpouring of clouds. Yet, our flesh arrives one way, while His comes another. We are called children of God, yet He is the Son of God in a unique manner. His cloud came from the Virgin; He is the eternal Son, consubstantial with the Father. Who is among the clouds that may be compared to the Lord? Who among the children of God can equal Him? Let the Lord Himself reveal if He can find someone like Him. "Who do people say that I, the Son of Man, am?" This inquiry arises because I am seen among you and perhaps appear commonplace; tell me, who do men believe I am? Truly, when they observe the Son of Man, they see a cloud; however, they respond, "Some say You are John the Baptist; others believe You are Elijah, or Jeremiah, or one of the prophets." A multitude of clouds representing sons of God is noted since Jeremiah, Elijah, and John are called sons of God due to their righteousness and holiness. Their nature as God’s messengers likens them to clouds.
"You've asked what clouds represent Me; so I ask you, who do you say that I am?" Peter, speaking on behalf of them all, boldly proclaimed, "You are the Christ, the Son of the living God" (Matthew 16:13-16). Not as those children of God, who cannot measure up to You: You came in flesh, not as clouds lacking Your stature.
"God is greatly to be revered in the assembly of the righteous; reverence surrounds Him" (Psalm 88:7). God is omnipresent; thus, who is with Him, who is everywhere? If God possesses those around Him, He would appear limited. His supreme greatness is boundless; who lingers around Him, except He, who exists everywhere, chose to be born in the flesh in one location, dwell among a singular people, be crucified and resurrected in one place, and ascend to heaven? In each of these acts, He had Gentiles in attendance. Had He remained in the same location to perform these deeds, He may not have been great or feared universally; yet, because He preached earnestly, sending forth heralds of His name across the globe and performing miracles through them, He became mighty and instilled awe.
